Overview
Skull O'Maniac is a B Tier consumable support card at cost 0 that buffs enemies in exchange for bonus XP. One-time use, lasting effect. Primary role: Mannajja evolution component — the single required material, making it mandatory pickup in any Arca or Mannajja-targeted run.
The enemy buff is a real risk, but runs with sufficient build completion handle the buff without major difficulty. Missing Skull O'Maniac prevents Mannajja evolution entirely.
Evolution Use
Skull O'Maniac + Song of Mana → Mannajja
Single-material evolution — Skull O'Maniac is the only evolution requirement. Never miss it in Mannajja-targeted runs.
Why Run Skull O'Maniac
- Cost-0 bonus XP (consumable, lasting growth boost)
- Required Mannajja evolution component (only material)
- XP acceleration for earlier evolution timelines
- Risk (enemy buff) is manageable in sufficiently developed builds
Synergies
- Song of Mana: direct Mannajja evolution component
- Arca: Mannajja post-evolution peak synergy
- Growth efficiency arcanas and relics: additive XP acceleration
- Stardust Anvil: Mannajja post-evolution gem development
Risk Assessment
Enemy buff is a real downside — evaluate run strength before use. However, the value of Mannajja evolution (the top single-target finisher in the game) almost always justifies the tradeoff. Never pass on Skull O'Maniac in Mannajja runs.
Tier Summary
General: B / Mannajja builds: Mandatory
Enemy buff risk slightly distorts the risk-reward. As the sole Mannajja evolution material, pickup priority is absolute in Arca and Mannajja builds.
