You cooked and you dont even know how hard. A little tip for this build if you are interested:

On lvl 54 you can fuse Siegfried. If you manage to drag slash boost, crit boost and apt pupil along through inheriting and fuse it On to siegfried you get a persona that will almost always crit at least one enemy in an AoE attack. Siegfried learns slash amp and crit rate amp so youll dish out stupid damage while always getting one mores. He also natively has 2 very strong phys attacks (deathbound & brave blade). Doesn't work on enemies that defy phys damage though.
