Tips
- Battlefield Warlord title (1.5%, 100 pity) is required for the Strongest Shinobi fighting style
- Path Fragment (0.56%) is the rarest drop — extremely rare at 0.4% effective rate
- Power Remnant (5.11%, need 15x) and Battle Sigil (2.94%, need 8x) are also needed for the F Move
- Bring an endgame build — 2 Billion HP requires sustained high DPS
- Abyss Sigils can also be farmed from this content for summoning the Atomic boss
