Catch Panthalus without restarting the whole ritual
The one endgame step that punishes a mistake hardest. Everything you set up before the summon so a bad hit doesn't cost you the fight.

The Panthalus catch at a glance
- Type / level
- Water, roughly level 70
- Counter
- Electric — Helzephyr Lux or Beakon (both catchable in the desert)
- Key item
- Ring of Mercy — caps your mount's damage at 1 HP remaining
- Ring of Mercy caveat
- Only protects mount damage — active Pal hits and status effects (burn, poison) can still kill it
- Watch for
- Wide tornado-style AoE attacks — a flying mount helps you dodge
- Kill instead of catch
- Forces a redo of the fight and summon
- After the catch
- Talk to the Researcher again — the mission doesn't close otherwise
The one mistake that costs you the whole ritual
Panthalus is the gate to the World Tree, and it's the fight on the route where killing the boss instead of capturing it forces you to redo the summon and the fight. That single failure mode is what makes people dread it — so the whole trick is preparation, not reflexes.
What to bring
Before you summon: prep an Electric answer — Panthalus is Water-type, and Helzephyr Lux or Beakon are both catchable as early as the desert biome. Equip the Ring of Mercy so your mount's damage physically cannot drop the target below 1 HP. The important caveat most guides skip: the Ring only protects your mount's hits — your active Pal's attacks and status effects like burn or poison can still finish Panthalus off outright, so watch your team's skill choices as carefully as your mount's.
The fight itself
Read the fight as a capture, not a kill. The encounter is scripted down to a sliver of HP where any sphere is a guaranteed catch. Panthalus throws wide tornado-style AoE attacks that are hard to dodge on foot — fighting from a flying mount lets you reposition and keep pressure without eating them.
The step everyone forgets
After the catch, the step everyone forgets: talk to the Researcher again. The catch alone doesn't close the mission — he does. Skip it and the World Tree chain stays stuck.
