Effect
A permanent Blacksmith Power-Up. Each rank increases all cards' Area (AoE radius). Range-based weapons cover more ground with each upgrade.
Priority: Medium
- High value in AoE-weapon builds (Holy Water, King Bible, Thunder Loop)
- Standard builds generally prioritize Might and Recovery first
Recommended Builds
- Holy Water evolution (La Borra): Larger purification zone clears wider screen sections
- King Bible build: Extended orbit radius hits more enemies per rotation
- AoE-focused Crawlers (Pasqualina): Synergizes with her innate Area stat
Per-Rank Effect
Area increases incrementally per rank. Invest when coins are surplus or when your main weapons are AoE-type.
Notes
Minimal benefit for projectile weapons (Knife, Runetracer). Prioritize Amount Gem or other Power-Ups for those builds.
