Capture the Compass
Part of Pride of the Valkyries: open only while the event runs, from its wave 3.
What to do
- Capture
Seidh. - While this quest is open,
Seidh turns up in wild battles anywhere (now and then), at your strongest Moga's level. - Weaken it first: the lower its HP, the better the chance. A Master Seed always works.
