⭐ High Farm Priority
Primary Dewelion fragment route via Castle Siege. Chain with Mendicant King for efficient crafting.
Tips
- Defeat both Bannerets — their keys open side routes and the ladder to the Ode Lantern
- Interact with the Ode Lantern atop the fort to draw Malrog out
- Fire pots or fire abilities briefly stun him — burst during the stun window
- Charge attack: dodge perpendicular, then hit from behind during recovery
- Multi-slash chains: roll with the swing direction, never trade inside the combo
Recommended pacts
Recommended Pact: Orengall — Packhunter draws aggro while you backstab during siege add waves
Recommended Pact: Ode Tempest — Fire synergy plus Atmos Sphere for surviving multi-slash chains
Recommended stats
Late mid-game with fire access; melee backstab or ranged kite. Siege add control required.
