Alright so I tried battling King Desius without all seals activating and damn these buffs are insane. I've only had problems with Cereth so far and thought I was doing kind of good in this game since my Sylesties are also quite high in level but I don't have the slightest clue on how to activate those seals... I tried transcripting the inscriptions on each seal, but my limited vocabulary doesn't allow this. I just can't get the hang of how to activate them... I tried it already with myself, Jinxie and my Sylesties but it still didn't do a thing. Any tips? :c

I really can't remember much about the seals. Iirc you use a pet to break the seals? I can tell you however, that this thread helped me a lot. Check out the second page if you want to know exactly what pet to use with which seal.

Oh yes! This should help. Thank you very much ^.^
