Dota Auto Chess: Patch Notes List 2019

This list contains all the Dota Auto Chess patch notes released in 2019. All the changes that affected the game have been gathered and explained.

The Auto Chess developers seldom release a full list of all the updates, so understanding what actually changed in a particular patch is really troublesome.

Luckily, in the Auto Chess community there are several fans and players ready to lend a hand. I sincerely thank Nostrademous: he analyzes the game code changes after every update, and granted me the permission to use his reports to compile these patch notes.

I have included all the changes from February onwards, and will keep updating this list over time as soon as proper info for each patch is provided.

• These patch notes contain also code and file changes, and a few personal comments from the author.

• When a detailed analysis was not available, I have just summarized the content of the patch.

• The DAC developers requested to not disclose unreleased content to not spoil the future patches, so any info on new heroes, ability changes, special units, etc. won’t be presented until they make it to the live client.

Abilities

• Lina's Fiery Soul (obtained on successful Laguna Blade cast) - grants 40/60/80 attack speed bonus for 30 seconds.

• Warlock Buff - OnAttackLanded effect has been removed (this is what healed units for 20% damage previously)

  • This is now triggered when calculating damage to a unit by an attacker instead (seems to work in a similar manner as before but with 10% / 20% buff from Warlock synergy applying to all damage sources (includes spells) but post damage mitigation)

  • The lifesteal now applies to the casting unit of the damage source and returns 10% / 20% (3, 6 warlocks) of the post-mitigated damage value. So it works with spells, but only heals the damage source caster, meaning, it would not heal techies as the "mine" is a separate unit that is created on the chess board and originates the damage separately from techies. However, for Razor or Zeus, it would heal for appropriate % damage of each target hit as they are the caster of the AoE spell

  • I did not have a chance to test this in-game yet, so apologies in advanced if my understanding is incorrect or flawed

Units

• Shadow Shaman 3* got all new cosmetics

• Bounty Hunter 3* got new cosmetics

• Witch Doctor 2* and 3* got new cosmetics

• Triple Kill and Rampage Banners Added

• Auto Combining Units on Bench available now

  • You can choose to enable or disable this

  • Looks like if you have 2 on your bench, no space left, and a 3rd available to buy, it will auto combine with a temporary extra bench slot

  • Does not benefit / take-account-of Druid Racial

    • Be weary here ... if you have 2 Druids that are not combined, you buy a 3rd one, and the auto-combine is enabled, you will have a "/forehead" moment

• AI action selection has a larger variability (Random Number between 0.5 and 2.0 :: Used to Be Random Number between 0.2 and 1.0) so things are slightly more staggered (possibly - remember it's random). When a round start each chess will now require from 0.5 to 2.0 seconds to do their action.

  • local damage = min_damage + ((max_damage - min_damage)*(distance / max_distance)) or min_damage

Note: Mirana's Arrow works in a new and unique way - whenever your team plays against an enemy, a Mirror Copy of your team is also attacking another (potentially the same) enemy player on another board.

Mirana's arrow is coded to aim at the team you are fighting against on the other board (in order to gain the necessary distance to max out damage and stun). So the Mirana on your board will target enemies of the Mirror Mirana's board enemies and vice versa. This is why the range of the Arrow is set at 6,000. From SW cell of the Board in SW corner to the NE cell of the NE Board in game is a distance of 5,611 units. The Arrow Speed is 800 units per second.

The closer the enemy board you are targeting the higher the chance the unit you are aiming for won't move before arrow gets there, but the lower the damage and stun length and vice-versa. Also, The Arrow will "stop" on the first target it hits that belongs to that enemy. During PvE rounds (or if only 1 player is in game - aka "Lobby") it just picks an unlucky target on the board.

Death Prophet - DP - Cost 5 Undead Warlock

Ability changes

Nothing important - the added a Texture to the "outofgame" ability.

Game changes

• An attempt to fix a bug where the heroes are unattackable, invisibile, etc. They tried to prevent the recall of a chess piece that is being removed (through fast clicking of several commands).

• A fix for bench targets - they did this by adding the 'outofgame' ability to all chess pieces "in you hand" (which is their version of saying "on the bench").

  • It adds the INVULNERABLE modifier for those units.

Code analysis

Unit/Ability changes

• [CLASS BUFF] Knights - Probability of Divine Protection changed from 25,35,30 to 30,30,30.

• [RACIAL BUFF] Elementals - Bug fixed for Stone/Stun being only 2 seconds, should now be 4 sec.

Tooltip changes

• Knights’ Tooltips have been adjusted to indicate the above mentioned CLASS CHANGE

  • probably in all languages... I have only checked English..

• [TOOLTIP ERROR] There still is an error regarding the tooltip that tells you the cost/draw probabilities with a Level 9 Courier

CURRENTLY: "DOTA_Tooltip_modifier_hero_level9_Description"	"<font color=\"#bbbbbb\">($1)Chess: 22%%</font><br><font color=\"#bbbbff\">($2)Chess: 30%%</font><br><font color=\"#6666ff\">($3)Chess: 35%%</font><br><font color=\"#ff00ff\">($4)Chess: 20%%</font><br><font color=\"#ff8800\">($5)Chess: 3%%\n</font>"

As you can see, the ($3) is listed as 35%, while it should be 25%. The code does that correctly; just the tooltip is wrong.

SIDE NOTES

Knights

Shield Probabilities are now:

• (2) 30%

• (4) 51% <math: (1 - (.7 * .7))>

• (6) 65.7% rounded to 66% <math: (1 - (.7 * .7 * .7))>

Tiny

I looked at Tiny's stun duration and it's interesting.

The duration of the stun is 1.5, 2.5, 3.5 (1*, 2*, 3* respectively) + <the distance of the throw divided by 1000>

I believe each chess cell is 100 x 100 units. So it would be: sqrt(700^2 + 700^2)/1000 = 0.989949... I use 700 as you are already in cell 100,100 when you start and can max throw to 800,800.

At max range throw, corner to corner, this would be a stun of 2.5, 3.5, 4.5 (per * tier)

As you can see, we have 3 new Translations: German, Portuguese, and Swedish.

Item changes

• [CHANGE] SheepStick - It has a 30 second cooldown.

• [NEW ITEM] Blink Dagger - It allows you to blink to back rank of a Column (not Row or Diagonal) similar to how assassins work. 15 second cooldown. Drops as early as Round 10.

Unit/Ability changes

• [UNIT] Terrorblade - Increased minimum right-click damage (and thus average damage) by 10, 20, 40.

• [RACIAL] Troll Buff changed from 35/35 to 35/30.

• [RACIAL] Elemental Buff duration increased from 3 to 4. (Note: there might be a bug leaving this value to 2)

• [RACIAL] Human Buff changed from Persuasion (DISARM for 3 seconds) to Silence (SILENCE for 4 seconds) (small bug where the modifier displays for 5 seconds at the 1st tier, but silences for 4 seconds in reality - it should be 4 sec at all tiers).

• [UNIT] Crystal Maiden - Aura code cleaned up - still affects all units in a 800 radius.

• [UNIT] Tiny - I don't see a fix for Tiny Bug they claim they fixed... I just see the timer associated with the stun duration increased by 0.3 (if that fixes it, great, but I'm not sure how).

Game changes

• Team Colorized Health Bars (then reverted back to original).

• One Courier Model got bigger by 10%.

• More Detailed Stats being uploaded to the servers.

• Better functionalized code for Win, Loss, and Draw conditions of a Round (used to be all one function with conditional logic, now they are 3 separate functions).

• Enemy Couriers will now fly in your Game Arena if the enemy is on a 10-win streak.

• Structure of URL tokenizers for communicating with web-server modified.

• [UPDATE #3] Fixes placing things outside of map grid.

• [UPDATE #4] They increased the allowed Think function of all Timers from 0.01 to 0.02 seconds. Not sure what impact this will have.

• [UPDATE #4] They attempted to fix server crashes with item combining at round completion (again).

• [UPDATE #4] They removed code that could declare a chess entity "out of game" (somehow).

• [UPDATE #4] They added code to remove entities on board that didn't have a health bar from staying around indefinitely across all rounds (these are mostly graphical... an no it's not Slark's constant ult).

Item use note

The way Items will fire in game follows this hard-coded order: Refresher > Blink Dagger > SheepStick > Dagon > FrogGua (no idea what that is) > Check for Unit being Doomed or Hexxed or Voodoo'ed or Turned to Stone.

Tooltip inconsistencies (nothing new)

There are Ability Tooltips (when you hover over the ability of an unit), Modifier Tooltips (when you hover over a modifier when it is applied) and then Source Code actual values

• Assassins - Ability tooltip says: (3) 10% for 4x, (6) +20% for 4x :: code does: (3) 10% for 3.5x, (6) +20% for 4.5x :: Modifier Tooltip is correct.

• Mages - Modifier tooltip for (6) says -10% Magic Resistance (it's (3) -40% and (6) -40%), ability tooltip is correct.

• Knights - Ability & Modifier tooltip says: (2) 25% chance, (4) 35% chance, (6) 45% chance :: code does: (2) 25% chance, (4) 35% chance, (6) *30%* chance .

• Knights Note - Divine Protection gives a shield to knights that provide a +30 armor and +75 magic resistance buff for 3 seconds.

• Hunters - Ability tooltip says: (3) +25% damage increase, (6) +35% damage increase :: code does: (3) +30% damage increase, (6) +30% damage increase.

• Goblin - Ability tooltip says: +15 Armor and HP Regen :: code does: +15 Armor, +10 HP Regen :: Modifier tooltip is correct.

• Elves - Modifier tooltip says: +20% evasion at Tier 1, Ability Tooltip and Code are correct at 25% for Tier 1.

• [INFO] - Undead: there is an Undead (6) buff (-9 armor to enemies) coded - just not enough Undeads in game to ever reach it (tooltip only gives 2 & 4).

• [INFO] - Orc: there is an Orc (6) buff (+450 HP) coded - just not enough Orcs in game to ever reach it (tooltip only gives 2 & 4).

• [UPDATE] - tooltip updated correctly for changes to Troll, Elemental, and Human changes noted above.

Looks like there are no real changes other than two timers adjusted slightly for game-related changes.

This is the only thing of consequence, and it's really a minor one:

AddPickAndRemoveAbility - You will get an extra 0.5 seconds to have your pick and recall chess pieces capability enabled during round preparation. Perhaps this helps people with a bad latency, but I am unsure.

The bug they fixed must be related to a layout or style

February 3

Update 1

Files changed

Changed Files: maps ['normal.vpk']
Changed Files: scripts\vscripts ['addon_game_mode.lua']

Changes

This is a very minor patch.

1. A check for a null-pointer on some conditional code was added to prevent a possible crash/error.

2. Added a Timer to a `AddPickAndRemoveAbility` function.

3. Removed some commented out code.

Code analyzed

1. Lots of new courier models available.

2. Reverted some of the new data that moved from scrolling text to corner message box and supposedly made it configurable (I don't really track the style & layout script files).

3. Fix to SSR model probability (to address the float issue where they could never be picked). New chance prediction below.

local ran1 = RandomInt(1,10000)
	local ran2 = RandomInt(1,10000)
	if h:GetLevel() >= 7 and ran1 <= 1 and ran2 <= 1 then
		this_chess = GameRules:GetGameModeEntity().chess_list_ssr[RandomInt(1,table.maxn(GameRule

Unit changes

Keeper of the Light - Illuminate

• Cast Point changed from 0.5 to 0.1 (makes it able to release much faster now if interrupted or dies mid cast prep -- the channel time charge up for max damage is still 3.0 seconds - 0.1 - 1.0 seconds = 100 damage, 1.1 - 2.0 seconds = 150 damage, 2.1 - 3.0 seconds = 200 damage).

  Cast Point is the amount of time between the hero deciding to use an ability and the ability being considered actually cast (goes back to Dota2 and animation cancelling), put on cooldown, and consuming mana.

• Ability Cooldown reduced from 12, 10, 8 to 10, 8, 6

Kunkka

• Ghostship

  • Stun Duration changed from 1.4, 1.4, 1.4 to 1.4, 1.7, 2.0

  • Damage reduced from 200, 300, 400 to 150, 250, 350

• New Cosmetic Item (shark)

Necrophose

• Death Pulse

  • Heal values changed from 100, 150, 200 to 100, 175, 250

Disruptor

• Static Storm

  • Duration decreased from 3, 4, 5 to 2, 3, 4

Medusa

• 2* and 3* skin and wearable updates for everything

Queen of Pain

• Sonic Scream

  • Damage reduced from 250, 350, 450 to 200, 300, 400

Dragon Knight

• Elder Dragon

  • Splash Damage fixes

Morphling

• Waveform

  • Speed of ability execution increased by 50% (less likely they die before it goes off once animation starts)

Phantom Assassin

• No longer starts with 100 mana, but rather 0

Sand King

• Burrowstrike

  • Speed of ability execution increased by 50% (less likely they die before it goes off once animation starts)

Templar Assassin

• Attack Rate changed from 1.0 to 1.2 at all tiers (Attack Rate is not Attack Speed - it is the amount of time between attacks ... makes TA 20% slower)

Timbersaw

• Armor reduction from 10, 10, 10 to 6, 8, 10

Tiny

• Max Default Damage changed from 70, 140, 280 to 100, 200, 400

Enchantress

• 2* and 3* Enchantress gets some skin updates/wearables

Witch Doctor

• Attack rate updated from 1.5 to 1.4

Warrior synergy buff

• Changed from 6, 8, 10 to 7, 8, 9

Assassin synergy buff

• Crit Multiplier changed from 400% (4x) at both Tiers to 350% (3.5x) at first Tier, and 450% (4.5x) at second Tier -- note this is not the same as it used to be. Having more assassins used to only increase the chance to crit for 4x (10% at first tier, +20% at 2nd tier buff for total of 30% chance to crit). Now it uses the same chance as I just described but at first tier the crit is for 3.5x and at 2nd tier at 4.5x.

Neutral units

• PVE Hellbears (Round 20 - Furbolgs) - damaged lowered by 10%

• PVE Wildwing (Round 25) - attack speed increased by 33%

Game changes

• Ban Wave incoming for cheaters

• VIP Tester Status

• Change to better inform folks when other players combine units (rather than the text scrolling)

• Same new format used for informing of player PvE results during a round

• Same new format used for informing of player PvP results during a round

• Same new format used for text messages sent by players via `say`

• Text appears at round start stating it's PvE or PvP

• Attempt at fixing server errors due to item movement near end of round

• Fix to some cheats people were using to buy chesses for free

• Fix for PvE fights above Round 50 (currently at any modulo of 5 == 0 round above 5 it thinks it's PvE -- fixed to lookup a round array instead of using pure math)

• Added a timer when loading the mirror team of the player you are facing off against so combat doesn't start immediately (doesn't look like you can reposition yet in reponse, but it's a start in that direction)

• RandomUnitSelection (FindUnluckyDogRandom) changed to be random rather than last unit on the field

• Fix to mana gain calculation to be attacker and not caster based on Dagon (all levels) and Crown items

New URL messaging:

At the end of every round data about each players hero composition, MMR, level, gold, etc. gets sent to one of their sites so they can start tracking stats about hero balances and possibly cheaters.
