Starscourge Radahn: step by step
The festival arena
Radahn is fought in Caelid during the Radahn Festival. This encounter makes allied summoning signs a prominent arena mechanic. Locate signs without standing still under the boss’s distant attacks.
Opening arrows and melee
The fight starts at long range; giant projectiles threaten an exposed approach. Move between cover and summons before deciding when to close distance. Once near him, track weapon swings rather than staring at his huge character model.
Second phase and aftermath
Radahn gains additional gravity pressure, including a spectacular transition. Keep enough stamina to escape long area attacks. His defeat changes the world and enables a separate underground route that matters to Ranni’s questline.
