So the prevailing strategy seems to be to stop feeding him slimes after the split and just burn him. When he hits 2 stacks I just can't handle the damage. I have Relic and a good amount of Darklight with a few pieces of Hoplite from AK. With Defiance and the party buff I sit at 7k HP (6987 somewhere around there) and with the food I use I am at 7.2k. Is it pretty much just a PLD x2 fight? Or does the party have to continue feeding to keep the stacks down?
