Surviving Gertrud minions on Crisis difficulty with Pluvia/Mabbers ^^; - Exedra Crisis season 7

Yeah its rough out here with unlimted units. Still dunno how to survive phase 1 of boss yet xD. 4 indomitable guards, towering bulwark on pluvia/mabbers. Pluvia has kokoro support and MP portrait + mana infusion as 3rd crystalis Mabbers has Heroic grace as 3rd crystalis.
