Crimson Slayer — guide

In short

Crimson Slayer is a Rare Attack champion from the Knights Revenant faction with Spirit affinity. Her kit has Sleep on the A1, a turn-meter steal and an AoE Heal Reduction, but with 1,134 base ATK she brings almost no damage. Build priority: none — keep her in the Vault for fusion.

Strengths

• The A3 hits every enemy with an 80% chance to place 50% Heal Reduction for 1 turn — handy against healing waves in Faction Crypts.
• The A2 has a 70% chance to steal 50% of the target's turn meter, which can cut an enemy's turn short.
• The A1 lands three hits on random targets, each with a 30% chance to place Sleep for 1 turn.
• Aura: +17% Ally ATK in Faction Crypts — the only real team value she offers Knights Revenant.

Weaknesses

• 1,134 ATK and 96 SPD: no damage scaling, and she will not move first without serious gear.
• Sleep breaks on the first hit of damage and does nothing against bosses.
• Heal Reduction lasts only 1 turn and needs Accuracy to land — under 150 ACC she will miss.
• No buffs, no survivability, no HP- or DEF-based damage.

Where to use

Faction Crypts is her ceiling (2.5/5): her aura and Heal Reduction at least pay off there. Arena, Dungeons, Clan Boss and Hydra all sit at 2.0 — you have better options. Doom Tower is 1.5 and Chimera 1.0, so leave her out of those entirely.

Stats and gear

If you do take her into Faction Crypts: SPD 170–190, ACC 150–200 so the A2 and A3 land, C.RATE 100%, C.DMG 150%+, rest into ATK. The author's build lists no artifact sets, so put together Speed + Accuracy from spare pieces and don't waste good gear. For relics, Tempus Sanguinis is listed — use it if it is sitting idle.

Masteries and blessings

Gathering Momentum is the only mastery named in the build — take it in the Attack tree. The rest is standard: crit rate and crit damage in Attack, plus Accuracy from Support if she keeps missing. No blessing is specified; if you must pick one, take anything that adds damage.

Tomes

Books on a Rare kept for fusion are a waste. If she is actually in your Crypt team, book the A3 first: it upgrades both the debuff chance and the damage, and level 8 cuts the cooldown by 1. The A1 and A2 only with spare books.

Verdict

Vault (fusion). A narrow Faction Crypts pick and not much else.
