Yelagirna — guide

In short

Yelagirna is an Epic Orc Attack champion of the Spirit affinity, picked for debuffs rather than damage numbers. Her headline tool is the A3 that lands Block Buffs and Block Active Skills, plus a passive revive on kill. She shines in Hydra and Chimera, and should be built for Crit Damage and Accuracy with a clear aim at 100% debuff chances once booked.

Strengths

• A3: 6.1× ATK, always a critical hit, and a 75% (100% booked) chance to place Block Buffs plus Block Active Skills for 2 turns.
• A2 is an AoE with 4× ATK and a 50% Decrease ATK for 2 turns — cuts the damage of waves and Hydra heads alike.
• Passive revives a random ally with 50% HP every time she kills an enemy, a free revive in long fights.
• Aura: +30% ATK for allies in Faction Crypts, and it buffs her too.
• A1 hits twice and grants herself a 50% Increase ATK after a kill.

Weaknesses

• Thin base stats: 1,365 ATK, 837 DEF and 95 SPD — she is no nuker and dies before her turn without support.
• Nearly dead weight in Doom Tower and Hard mode (1.5 and 2.0 out of 5).
• Without Accuracy and tomes the 75% chance is a coin flip, and a 4-turn cooldown leaves her idle.
• All her control is single-target on A3 — she does not lock down a team.

Where to use

Best homes are Hydra (4.0) and Chimera (4.0), where Block Buffs and Block Active Skills switch off half the boss mechanics. Next up: Arena (3.5, especially 3v3 as pinpoint control), Faction Crypts (3.5, her own aura) and Clan Boss (3.5, Decrease ATK as insurance). Dungeons are average (3.0). Keep her out of Hard mode and Doom Tower (2.0 and 1.5).

Stats and gear

Priority: Speed → Accuracy → Crit Damage → ATK. Rough targets: SPD 170–200, ACC 200+ (250+ for Hydra and Chimera), C.DMG 180–220%, C.RATE 70–100% (A3 always crits, but without crit rate A1 and A2 hit like a wet noodle), ATK as high as your gear allows.

• Sets: Savage, Cruel or Lethal as the base, filled out with Offense, Critical Rate or Crit Damage.
• Use Accuracy/Speed pieces to reach the thresholds.
• Relics: Malefic Talon, Irethi Coronet.

Masteries and blessings

Offense tree with Pierce Defenses and Boss Slayer as the key picks, plus crit damage nodes. For the second tree, Support with Sniper (extra debuff chance) is the natural fit, or Defense if she keeps dying before acting. Blessings are low priority for an Epic debuffer — a cheap Accuracy or survivability one is plenty.

Tombs

Book the A3 first: 75% → 100% chance and −1 turn cooldown is exactly what she is hired for. Then the A2 for a reliable AoE Decrease ATK, and the A1 last.

Verdict

A narrow but genuinely useful Hydra and Chimera tool: two nasty debuffs and a free revive on kills. The site author's call is vault (fusion) — build her only if you truly lack Block Buffs for Hydra.
