On a fatal hit, survive at 1% HP, gain 5 seconds of invulnerability and summon 30 Valkyries.
When to choose it
Valkyrie Helmet: On a fatal hit, survive at 1% HP, gain 5 seconds of invulnerability and summon 30 Valkyries.
Use the five-second protection window to leave danger after activation. The Valkyries can fight while you find a safer route, but 1% HP leaves very little margin when protection ends.
Pairings and trade-offs
Phoenix Feather returns you with 30% health instead. Knee Protector creates a shorter protection window after a module level-up, rather than waiting for a fatal hit.
