DESCRIPTION
Magma Bell reduces incoming damage from flame-based attacks and magma hazards. It does not grant immunity—move decisively through lava sections, and use it to soften chip damage in fire-heavy fights.
Mount Fay routes: safer traversal across magma-rock corridors
Boss prep: reduces chip damage for flame-heavy bosses (e.g., Last Judge)
Synergy: Warding Bell (heal window shield), Fractured Mask (one-hit shield)
BEST USES & FIRE ROUTES
Deep Docks Traversal
Cross magma-rock corridors faster with reduced chip damage
Fire-heavy Bosses
Equip for flame phases (e.g., Last Judge) to soften hits
