TFT champion pool size, roll odds, and draw chances in Set 13

ArticlesVincenzo "Skulz" MilellaNovember 20, 2024Guides, Champions6 Comments

The chances to draw a specific champion in TFT depend on their gold cost, the number of the same units in play, and your level.

Teamfight Tactics has RNG elements, so your success in the game is also influenced by your luck. There is no way to know in advance which unit you will find the most during a match, neither their synergy or class.

Generally, you can build a strategy based on the following factors.

If there are already several two or three-star units of a particular champion, your chances to find additional units of the same kind are drastically reduced.
Your level is also crucial because according to it you will find a distinct amount of units with a certain gold cost. For example, if you have tier 1-2 champions that are close to reaching three stars, you should avoid leveling past 4 or 5 as the chance to find them will decrease.

Set 13: Into the Arcane

Unit roll odds by level

The following table shows the champion pool size and the chance to draw a specific tier unit.

The table is responsive. If you are using a phone, you may have to turn it sideways for a full view. Otherwise, zoom in or press on the grey area to swipe it.

Note: the table will always be updated to the latest Set 13 patch.

Champion pool size

There is a fixed champion pool size for each tier which is shared among all players:

Tier 1: 30
Tier 2: 25
Tier 3: 18
Tier 4: 10
Tier 5: 9

These numbers represent the total copies of tier X champions that exist in the store, not the unique champions. For example, there are 30 copies of each tier 1 champion, etc.

If a player is defeated or if some units are sold, the champions go back into the common pool. Rioter Adam Cohen also clarified that champions available during the Carousel round are pulled from the pool.

You must reach at least level 5 to find tier 4 champions and level 7 for tier 5 ones. Considering the data above, upgrading a tier 4 or 5 unit to three stars is quite difficult, particularly the latter as you need nine out of the ten copies available for each champion.

Set 12: Magic n’ Mayhem

Unit roll odds by level

Patch 14.18

We’re making hitting 4-costs a little more consistent at level 8. Currently, rolling down on level 8 to power spike is higher risk than a lot of reroll strategies that have already spiked, especially when you have to seek out specific 4-costs to button up your comp.

Level 8: 18/27/32/20/3 ⇒ 18/25/32/22/3

Set 11: Inkborn Fables

Unit roll odds by level

Patch 14.12

We’re doing a revert of the shop odds changes we made back in 14.8 that aimed at reducing the power of 3-cost reroll comps. Those changes, combined with powerful 4 and 5-cost buffs went too far. The odds revert, and a few power adjustments for our overperforming 4-costs over the last few patches should have us in a new meta where reroll, fast 9, and everything in between can live together in harmony. Alongside this change, we’re also giving a little love to the reroll carries that haven’t been able to do much carrying as of late.

Level 7: 20/33/36/10/1% ⇒ 19/30/40/10/1%

Patch 14.9

Less gold, and lowered odds should help combat the dominance of three-star 4-costs as the most prevalent win condition in lobbies.

Level 8: 18/25/32/22/3 ⇒ 18/27/32/20/3
Level 9: 10/20/25/35/10 ⇒ 15/20/25/30/10

Patch 14.8

We’re seeing 3-star 3-costs dominate the meta due to the consistency with which players can hit them (when uncontested) and the power level of 4-costs being lower than we’d like (see Tier 4 later). Aside from a couple of outliers, we are happy with 3-costs being as powerful as they are, so we’re making some leveling changes here to make them slightly harder to hit while also lifting the power level of 4-costs.

Level 7: 19/30/40/10/1% ⇒ 20/33/36/10/1%

Champion pool size

There is a fixed champion pool size for each tier which is shared among all players:

Set 6: Gizmos & Gadgets

Updated to Neon Nights!

Unit roll odds by level

Patch 12.2

5-costs have been strong throughout Gizmos & Gadgets, and they should be, cause they’re Legendary units. But by hitting Level 8, players are able to get a game dominating 2-star 5-cost a bit too often. We’re making it slightly less consistent to hit a 5-cost at Level 8, but adjusting Level 9 to be slightly more consistent.
As a general reminder, these percentages are for each individual unit card that appears in your shop, so the total chance of seeing a 5-cost in your shop at level 8 went down from 22.7% to 19.5%, and the total chance of seeing a 5-cost at level 9 went up from 55.7% to 58.2%.

Level 8: 15/20/35/25/5% ⇒ 16/20/35/25/4%

Patch 11.11

Shop Rates (Standard and Hyper Roll)

TLDR: Reroll for your 2-cost three stars at Level 6 and your 3-cost three stars at Level 7.
Giving clearer and stronger windows to hit 2 and 3 cost champions by differentiating shop rates at Level 6 and 7.

Level 6: 35/35/25/5/0% ⇒ 25/40/30/5/0%
Level 7: 19/35/30/15/1% ⇒ 19/30/35/15/1%

Patch 11.9 - Reckoning

During Fates, hitting a 3 star 4-cost was made easier with the Chosen system. With it’s removal, we’re rebalancing some of the Shop odds changes we had to make in order to balance the Chosen system.

Level 7: 22/35/30/12/1% ⇒ 19/35/30/15/1%

Set 4: Fates

Updated to Festival of Beasts!

Unit roll odds by level

Note: the table will always be updated to the latest Set 4 patch.

Patch 10.25

"10.24 had lots of changes to roll odds that made the dreaded 4-1 roll down less of a nat 20 or bust moment. We’re honestly shocked with how well those changes went, so we have a minor tweak today to see slightly more four cost champs."

Level 7: 24/35/30/10/1 ⇒ 22/35/30/12/1

Patch 10.24

Unit odds updated.

Patch 10.21

Removed the Fates change to the shop that prohibited unbought champions from repeating in consecutive shops.

Patch 10.20

Champion probability by Tier at level 8: 14/20/35/25/6% ⇒ 14/25/35/20/6%

Aided by the Chosen mechanic, we're seeing 3-star Tier 4 champions too frequently for their power level. We're dialing down their frequency of showing up at level 8 to make sure that their rarity is more appropriate.

Patch 10.19

Consecutive shops will not repeat unbought champions.
Bag odds for Level 5: 40/35/20/5/0 ⇒ 45/30/20/5/0
Bag odds for Level 6: 25/35/30/10/0 ⇒ 30/35/25/10/0

Chosen champions odds

In TFT Fates, some champions can be marked as “Chosen”, which means that one of their traits counts as two of that trait.

These champions are already at 2-star level, so they cost three times their normal 1-star price and come with some extra power

Chosen Bonus Spell Power: 30⇒15

Chosen Bonus Health: 400⇒300 (The bonus 200 health baseline that Chosens receive just for being Chosen is not affected here)

Patch 11.2

Chosen Shop Odds

Consistency Buff.

Level 6: 15/45/40/0/0 ⇒ 0/60/40/0/0
Level 8: 0/15/45/40/0 ⇒ 0/0/60/40/0
Level 9: 0/0/15/45/40 ⇒ 0/0/0/60/40
Reduced the chances of rolling a Chosen slightly, as in you probably wouldn’t have noticed if you didn’t read what you’re reading right now. This outta make it just a tad more difficult to force comps.

Patch 10.24

Increased the base odds of rolling a chosen slightly.
Chosen Bonus Attack Damage: 30 ⇒ 20
- This affects Yasuo, Aphelios, Zed, Xin Zhao, Ashe, Jhin, Talon, and Warwick.
Cultist: A Chosen Cultist now only provides +1 star level to Galio instead of double the Chosen’s star level.

Patch 10.22

There are a couple of traits that have an unintentional anti-synergy with the chosen mechanic as they lose value with less units on the board. We're changing the rules of those chosen to count as two units for the sake of their traits.

Cultist Chosen now count as 2 Cultists and will grant Galio double the amount of star levels (e.g., a two-star Elise will grant Galio four star levels instead of two).
Keeper Chosen now count as 2 Keepers and grant double the amount of shields

Patch 10.21

Modified the Chosen appearance rate to reduce some of the worst luck cases and streakiness.
You are now guaranteed to see at least one Chosen by 2-2.

Neeko's Help

Currently Neeko's Help pulls a unit from the pool. If all the units are out of the pool (very rare but can happen), Neeko will actually bounce off and not work. So you will still be able to count the number of active units correctly.
— Riot Mort

Patch 10.12

Neeko’s help now always works, even if there are no more copies in the bag.The extra champ generated is extra, and when sold or the player is defeated does not go back into the bag.

We're decreasing the number of each champion in the pool. It will be much more difficult for multiple players to build similar teams. Keep an eye on what your opponents are building and find the open synergies for maximum success.

Note that Teamfight Tactics is constantly evolving, so it is hard to predict for how long this data will be correct. I will update this page as soon as new info is available.

Patch 9.18

We’ve made some minor adjustments to how likely which tier champions will appear at a few different levels. We’re hoping these make clearer early, mid, and late game phases.

Level 3 by Tier: 65%/ 30%/ 5%/ 0%/ 0% ⇒ 70%/ 25%/ 5%/ 0%/ 0%
Level 5 by Tier: 37%/ 35%/ 25%/ 3%/ 0% ⇒ 35%/ 35%/ 25%/ 5%/ 0%
Level 6 by Tier: 24.5%/ 35%/ 30%/ 10%/ 0.5% ⇒ 25%/ 35%/ 30%/ 10%/ 0%

Patch 9.18: Tier 3 champions in pool reduced from 21 to 18.

Average gold needed to find a specific champion

The following table, provided by reddit user ereklo, shows how much gold you must spend on average to find a specific champion via rerolls.

For example, if you are level 6 and you are looking for a tier 4 champion such as Brand, you will spend 36.8 gold on average to drop him.

Note: this table is not updated to patch 9.18

if a specific unit is already in the hands of many players, you might need to roll more, and thus spend more gold than expected to acquire it.
if a specific unit is held by just a few players, your chances increase, so you will require less gold to find it.

This is the math formula used for the chart: 2*(1-(1-X/N)^5)^(-1)

X is the champion drop rate by level shared by Riot dev Ed “SapMagic” Altorfer in July.
N is equal to the number of different champions available at each tier: 12 for tier 1, 12 for tier 2, 12 for tier 3, 9 for tier 4, and 6 for tier 5.
X/N is the chance of picking the right champion out of one time.
1-X/N is the chance of picking the wrong champion out of one time.
(1-X/N)^5 is the chance of picking the wrong champion out of five times (one reroll).
1-(1-X/N)^5 is the chance of picking the right champion at least one out of five times.
(1-(1-X/N)^5)^(-1) is the average amount of rerolls you have to do before finding the champion.
2*(1-(1-X/N)^5)^(-1) is the average amount of gold you have to spend before finding the champion.

The chart also assumes that champions of equal cost are being held in equal amount.
