The boss hits hard, can parry your attacks, and can break your guard. Cover plus Cero is the recommended starting approach because it reduces the time you spend trading blows at close range.
- Move beside a square pillar or building and place it between you and the boss.
- Keep the opponent on the other side of the obstacle and press R to fire Cero.
- Wait for Cero's cooldown while maintaining that separation.
- Repeat the attack until the boss is defeated. Reposition if the opponent comes around your cover.
Use the obstacle to control the fight, but stay ready to move: cover does not make you immune to every attack. Watch the boss and your health between casts instead of assuming the position will remain safe.
A building can serve the same purpose as a pillar. Another option is to double-jump onto a building near the arena's left corner and fire from above; the pillar approach is a more straightforward starting point because it does not require finding a way onto the roof.
Direct melee is also viable. A speed-focused setup can win this challenge, so you do not have to rebuild solely for Cero if you already handle close-range combat well. Speed investment is an option, not an unlock requirement. Given the boss's parries and guard breaks, favor openings between its attacks over prolonged exchanges.
