SP Crow Build Guide — Blood Raven Mage — Abyss Hunters

Star	Branch	Effect
T0	Domain Debuff	Enemies in domain: -35% ATK speed, -35% move speed. Crow heals 10% lost HP/sec
T1	HP Stacking	Every 5 hits received: +2% max HP permanently (max 50 stacks = +100% max HP)
T2	Domain Enhancement	Enemies in domain: -25% ATK. Enemy death heals all allies 5% of Crow's max HP
T3	Immortality Field	Allies in domain CANNOT DIE. On Crow death: 40% max HP/sec to ALL enemies permanently

Skill: Blood Raven Domain

Auto-attack: Apply curse to target — target takes 10% of Crow's max HP per second as damage and is forced to attack Crow for 3 seconds. Max 3 curse stacks.

Active Skill: Deploy Blood Raven Domain (radius 3):

Crow takes 5% of his own HP per second
Enemies in domain take 35% of Crow's max HP per second
Enemies are forced to attack Crow
Duration: 6 seconds

All damage in this kit scales from Crow's maximum HP — not ATK, not skill DMG, not elemental stats. This fundamentally changes how you build him.

Recommended Card

Best: Mud Monster (★3, All)

Star	Passive
★1	+15% max HP
★3	15% max HP shield at battle start

Synergy: Every point of HP is both survivability AND damage for Crow. Mud Monster's +15% HP directly scales Crow's Tier 1 stacking damage (% of max HP), the immortality domain (30% max HP heal/sec), and the death trigger (40% max HP/sec to enemies). The battle-start shield buys time to reach Tier 1 stacks safely.

Priority Stats on Any Card

Priority	Stat	Why
1	+HP flat / +HP%	Directly scales all damage and domain effects
2	+DEF / +DR%	Keeps Crow alive longer for more Tier 1 stacks
3	+Healing received	Amplifies Tier 0 self-heal

Budget: Any card with HP substats

Even a low-rarity card with HP flat is better than a high-rarity card with ATK stats on Crow.

Gem Setup

Weapon / Ring Gems (Type 1 — Offensive, 6 sockets total)

Equipment	Socket 1	Socket 2	Socket 3	Why
Weapon	Ruby (ATK)	Ruby (ATK)	Ruby (ATK)	ATK for faster auto-attacks to apply curse stacks
Ring	Ruby (ATK)	Ruby (ATK)	Ruby (ATK)	More ATK = faster curse application via autos

Why Ruby when damage scales from HP? Crow's curse is applied via auto-attacks. Higher ATK means auto-attacks connect faster and more reliably, ensuring 3 curse stacks are maintained. The ATK itself does not contribute to curse damage (that scales from HP), but it ensures the curse is applied. Elemental gems, crit gems, and Holy Crystal are all wasted — Ruby is the least-bad option for offensive sockets.

Armor / Amulet Gems (Type 2 — Defensive, 6 sockets total)

Equipment	Socket 1	Socket 2	Socket 3	Why
Armor	Emerald (HP)	Emerald (HP)	Emerald (HP)	HP = damage. Every Emerald gem scales ALL of Crow's kit
Amulet	Emerald (HP)	Emerald (HP)	Emerald (HP)	Full HP. No exceptions. No Diamond, no Sapphire

Why 6 Emerald with zero defensive diversity? On every other hero, you mix in Diamond or Sapphire for Abyss survival. Crow is different — his Tier 1 gives +100% max HP from getting hit, Tier 0 heals him, and Tier 2 reduces enemy ATK. His survivability comes from his kit, not from resist gems. Every Emerald gem is simultaneously offense AND defense.

Equipment Affixes to Target

Weapon

Priority	Affix	Why
1	HP flat	HP = damage for Crow, even on weapon
2	HP%	Multiplicative HP scaling
3	ATK%	Faster curse application (minor)

Armor

Priority	Affix	Why
1	HP flat	Primary damage scaling stat
2	HP%	Multiplicative with HP flat
3	DEF%	Survive longer = more Tier 1 stacks
4	DR%	Flat damage reduction extends Crow's life
