Mastery Guide
Mastery is the per-ability EXP track. Every zombie kill funnels EXP into the ability you currently have slotted, climbing through four milestones up to Lv100 — the only way to unlock that ability's V-skill (its ultimate). This page covers per-kill yields by difficulty, the milestone breakpoints, and which Gravewalker map gives you the fastest path to Lv100. Updated .
Why Mastery Matters
- Lv75: +35% DMG — the highest single-stat power spike in the game outside of rebirth.
- Lv100: unlocks the V-skill (ultimate ability). This is permanent and unique per ability.
- Per-ability: mastery tracks each ability independently. Swapping slots does not transfer EXP.
- Total EXP to Lv100: 257,400 — calculated from the formula
(150 + 5050) / 2 × 99.

Mastery Milestones
| Level | Bonus | Why it matters |
|---|---|---|
| Lv25 | +2 Walkspeed | Minor mobility for early-game farming. |
| Lv50 | +2 DMG | Flat damage — small but stacks with multipliers. |
| Lv75 | +35% DMG | Major DPS spike — the most efficient mastery breakpoint. |
| Lv100 | Unlock V-skill | The ability's ultimate becomes usable. Lv100 is the only way to unlock it. |
EXP per Zombie Kill (by difficulty)
| Difficulty | EXP / kill | Notes |
|---|---|---|
| Normal | 5 | Standard zombie waves. |
| Hard | 7.5 | +50% over Normal. |
| Nightmare | 10 | +100% over Normal. |
| Gravewalker | 20 | +300% — the recommended farming difficulty. |
EXP applies only to the ability you currently have equipped in the slot that landed the killing blow. Multi-slot rotation does not split EXP — the last-hit slot gets full credit.
Farming Routes — Gravewalker EXP per Run
| Map | EXP / run | Notes |
|---|---|---|
| Gravewalker Shibuya | 8,900 | ~6-8 min/run · Tower of Babel route preferred. |
| Gravewalker Impel Down | 6,500 | ~7-10 min/run · Open layout, less density than Shibuya. |

Time to Lv100 — The Math
Total EXP needed: 257,400. Running pure Gravewalker Shibuya at 8,900 EXP per run takes ~29 runs. Impel Down at 6,500 EXP per run takes ~40 runs.
- Shibuya path: 29 runs × 6 min = ~174 min · 29 runs × 5 min (optimal) = ~145 min
- Impel Down path: 40 runs × 7 min = ~280 min
- Best case (Shibuya optimal): ~87 min if you average 3 min per run with stacked DMG buffs.
Recommendation: run Gravewalker Shibuya. The 8,900 vs 6,500 EXP-per-run gap (37% better) dominates the per-run time differential. Pair with a high-DPS ability (Spin, Head of Hei, Akaza, Saiyan) and Reaper / Flash trait — the ability you are mastering doesn't have to be the one carrying DPS, as long as it lands the kill shot.
Mastery Stacks with Upgrade and Rebirth
The +35% DMG from Lv75 stacks multiplicatively with rebirth and upgrade bonuses. For the same Spin Lv7 / R5 / Flash example from the Upgrade page:
- Base g-skill: 1881
- × R5: ×3.50
- × Flash: ×1.20
- × Upgrade Lv7: ×1.35
- × Mastery Lv75: ×1.35
- = ~14,397 per g-skill hit (vs 10,664 without mastery).
Mastery is the highest-ROI investment after Rebirth — no coin cost, just zombie kills. If you only have time for one Gravewalker grind today, push your main DPS ability to Lv75 first.
