Nail Build
- Unbreakable/Fragile Strength
- Quick Slash

Ideal for players favoring spell-based combat, this build leverages the power of Descending Dark, Abyss Shriek, and Shade Soul. Shaman Stone amplifies spell damage, and Spell Twister reduces Soul costs for more frequent spell casting. Grubsong helps maintain Soul levels, and Unbreakable/Fragile Heart provides extra health, allowing more focus on spell usage.

Best Build
- Unbreakable/Fragile Strength
- Shaman Stone
- Mark of Pride
- Grimmchild (Mandatory)
A hybrid approach works best against Nightmare King Grimm. Shaman Stone enhances spell effectiveness, crucial for spells like Abyss Shriek and Descending Dark. Unbreakable/Fragile Strength and Mark of Pride bolster Nail damage, useful when spell casting is risky due to the double damage threat.
Alternate Build
- Grubsong
- Sharp Shadow
- Shaman Stone
- Spell Twister
- Nailmaster's Glory
- Grimmchild (Mandatory)
This build emphasizes a defensive strategy, combining spells with Nail Arts. Shaman Stone and Spell Twister maximize spell damage and efficiency, while Grubsong ensures a steady Soul supply.
