Strategy
- 1This is a three-phase endurance fight — focus on survival first, damage second
- 2Eliminate the shadowy clones he spawns immediately; Caliburn uses feints where clones attack instead of him
- 3Stay close and bait melee attacks; distance gives him access to Arcing Crescent projectiles and Red Rain beam barrages
- 4Watch for Clone Clash — Caliburn pauses and summons multiple clones that stab at your current position
- 5Use perfect parries to break his stance — this is the fastest path to meaningful damage windows
- 6Stock up on Recovery Items and Palmar Pills; after defeating Corrupted Caliburn, another three-phase boss fight begins immediately
