Sorry, I misspeled the skill, it's actually called Soul Cluster, and like I said before it instantly kills my MC just like a Mudo spell.
What I want to know is how to avoid it, it looks like I have to use some item as it says here in the guide you sent me:
http://bmky.net/yarikomi/if/if_08.html I guess it's supposed to hit units with low Magic?My MC has low magic stat, but not the lowest on the team...
I sure have high level and great demons to easily beat him, the problem is that instant death spell...My gardian is Metatron.
Thanks for the help though!
