Conquering Grimm: Optimal Charm Builds for Hollow Knight's Troupe Master and Nightmare King
Grimm, a captivating figure in Hollow Knight, presents two formidable challenges: Troupe Master Grimm and Nightmare King Grimm. These battles demand precision, reflexes, and strategic charm selection. All builds require Grimmchild (occupying two charm notches).
Troupe Master Grimm: Charm Builds
This fight, while challenging, is slower-paced than Nightmare King Grimm, allowing for more deliberate attacks.
Nail Build:

- Unbreakable/Fragile Strength (mandatory for increased Nail damage)
- Quick Slash (for maximizing damage windows)
- Longnail (offers extended range, a viable alternative to Mark of Pride given Grimmchild's slot usage)
- Grimmchild (mandatory)
This build prioritizes maximizing Nail damage between Grimm's attacks. Aim for a Coiled or Pure Nail for optimal effectiveness.
Spell Build:

- Shaman Stone (mandatory for amplified spell damage)
- Grubsong (maintains Soul supply)
- Spell Twister (increases spell casting speed)
- Unbreakable/Fragile Heart (boosts health for spellcasting)
- Grimmchild (mandatory)
This build leverages the power of spells like Descending Dark and Abyss Shriek. Shaman Stone and Spell Twister are key for consistent damage. Grubsong mitigates the risk of running out of Soul.
Nightmare King Grimm: Charm Builds
Nightmare King Grimm is significantly faster and deals double damage. A hybrid approach proves most effective.
Optimal Build (Hybrid Nail/Spell):

- Unbreakable/Fragile Strength (for increased Nail damage)
- Shaman Stone (for amplified spell damage)
- Mark of Pride (boosts Nail range for additional damage windows)
- Grimmchild (mandatory)
This build balances Nail attacks with powerful spells like Abyss Shriek, capitalizing on damage opportunities.
Alternate Build (Defensive Spell/Nail Art):

- Grubsong (maintains Soul supply)
- Sharp Shadow (allows for safe dashes through attacks with Shade Cloak)
- Shaman Stone (for amplified spell damage)
- Spell Twister (increases spell casting speed)
- Nailmaster's Glory (boosts Nail Art damage)
- Grimmchild (mandatory)
This defensive build uses spells and Nail Arts, relying on Sharp Shadow for evasive maneuvers and Nailmaster's Glory to enhance Nail Art damage output. Grubsong ensures consistent Soul availability. Remember to utilize Shade Cloak effectively with Sharp Shadow.
