In short
- Masteries are permanent upgrades you unlock on each champion. There are three trees (Offense, Defense, Support) with 22 masteries each, 66 in all, arranged in six tiers.
- You unlock them with mastery scrolls from the Minotaur's Labyrinth dungeon, or pay gems to open a champion's masteries in one go. Guides report about 1,650 scrolls in total per champion.
- Some masteries are plain stats (+50 ACC, +3,000 HP...). Others change a fight: bonus damage, turn meter, extra debuff duration, counterattacks.
- A few picks are close to standard: Warmaster or Giant Slayer for damage dealers, Eagle-Eye for debuffers, Lore of Steel for champions that wear plain stat sets.
- Spend scrolls on champions you really use first. A mastery you can reset is cheap to fix; a champion you later bench is not.
How the trees are laid out
Each tree is a column of six tiers. Tier 1 offers two masteries and tiers 2 to 6 offer four each. Higher tiers are stronger and, in the game, are opened by working up from the tiers below.
| Tree | Theme | Typical user |
|---|---|---|
| Offense | Crit stats, bonus damage, damage when the target is low or weak. | Damage dealers. |
| Defense | DEF and RES, less damage taken, counterattacks, resisting crowd control. | Tanks, and anyone who must survive. |
| Support | ACC, healing and shield strength, turn meter, longer buffs and debuffs, set bonuses. | Healers, buffers and debuffers. |
Note Guides disagree on how many masteries one champion can hold in total and how many trees you can use at once (one reports a limit of 15 masteries over two trees, which fits the three scroll sizes below). Check the Masteries screen on any champion in your own game for the current rule. Checked 2026-10-15.
Getting them: scrolls and gems
- Scrolls come in three sizes: Basic, Advanced and Divine. Several guides give 100 Basic, 600 Advanced and 950 Divine, so about 1,650 for one champion, and say they must be spent in that order. They drop from the Minotaur's Labyrinth; higher stages give more.
- Gems can open a champion's masteries at once. The price reported by guides is 800 gems.
- Resets are reported as one free reset per champion and then 150 gems each.
Careful The gem and reset prices come from fan guides and may have changed. Look at the price in the game before you pay.
A common plan is to buy the masteries on one or two champions you are sure about, then farm the Labyrinth for the rest. More on where scrolls fit in your week in the daily routine and resources.

Stats that masteries give
Twelve masteries are plain stats. They add to the champion's stat sheet just like gear does, so they stack with the rest as described in where your champion's stats come from.
| Stat | Masteries |
|---|---|
| ATK | Blade Disciple +75 |
| C.RATE | Deadly Precision +5 |
| C.DMG | Keen Strike +10, Flawless Execution +20 |
| DEF | Tough Skin +75, Iron Skin +200 |
| RES | Defiant +10, Unshakeable +50 |
| HP | Steadfast +810, Elixir of Life +3,000 |
| ACC | Pinpoint Accuracy +10, Eagle-Eye +50 |
These are flat additions (C.RATE and C.DMG are percentage points, see every stat explained). Lore of Steel is different: it does not add a stat itself but makes the basic stat sets you wear slightly stronger, so it is worth most on a champion with several of them. See gear sets.
What usually goes where
The champion pages on this site suggest a mastery path for each champion, worked out from what its skills do. The patterns behind them:
- Damage dealers
- Offense tree: Deadly Precision, Keen Strike, a cooldown or damage pick at tier 4 (Cycle of Violence if the champion has big cooldown skills), then Warmaster, or Giant Slayer when the A1 hits many times. Against bosses these two bonus-damage masteries are capped by the boss's MAX HP, so the number of hits matters more than the boss's size. Skip kill-based masteries (Kill Streak, Whirlwind of Death) for boss fights where nothing dies.
- Debuffers
- Support tree: Pinpoint Accuracy, Charged Focus, Arcane Celerity, Master Hexer, Eagle-Eye. Longer debuffs and more ACC both make debuffs stay on the target more of the time; see Accuracy and Resistance.
- Healers and buffers
- Support tree: Lay On Hands or Shieldbearer, Healing Savior or Rapid Response, Lasting Gifts, then Timely Intervention or Elixir of Life.
- Tanks
- Defense tree: Tough Skin, Blastproof, Resurgent, Delay Death, Selfless Defender, and Iron Skin if the skills scale from DEF.
- Arena champions
- Arena rewards other picks: Ruthless Ambush and Kill Streak on attackers, Retribution, Wisdom of Battle, Harvest Despair and Unshakeable on defenders, and Evil Eye or Fearsome Presence on turn-meter and crowd-control champions.
Tip If a champion's best use is unclear, put the stat masteries first and leave the situational ones open until you have used it for a while. Scrolls are the slow resource; a reset costs gems.
