I have FINALLY advanced past the 3 Uriels, but now I am stuck on the final bosses of the next island...2 Laomus and Mighty Nathura.
I used Timerion, and equalized her, but then - under Hackster's possession - she used a moved that gave her 70000 more health. I thought self heals didn't work under possession? :(
I was also using Hackster and Shallinar btw.
