Yeah, but you have to be careful with that, he counteracts overdrives with a pretty powerful hit. I don't remember what it was called, but it took my people (20,000+ HP)down to about 3,000 HP
No problem, for starters DO NOT use Break HP limit it is useless.
Get armors like these:
Def + 30%
M.Def + 30%
Auto-Protect
Then for the 4th slot these:
Auto-Phoenix x2
Auto-Shell x1
or Ribbon
or Auto-potion(only having X-potions or better)
NO hit will deal above 9999 damage then, there's 1 hit of his that deals above it but then Auto-phoenix comes in.
And there's 1 hit that kills you no matter what you do, so therefor either Auto-life or Aeon as food.
