I drew a kaze gaara and mifune. They helped me a lot on pve and pvp. Going to keep stacking my seal scrolls untill I'm bored of them. Btw, if you want them tanky chars, just switch mood to hp and level ninja tools that gives hp. Also try to get +% defensive mods on 5 nature.

Ouch! Those must be super stacked instances/pvp teams you're facing. Maybe crowd control to keep those squishy chars alive longer?
