Let's Play Genius of Sappheiros (Extra) Part 21
Somemore rare mat questing.
Terminator MK-II:
My advice, look up the wikia. But, here goes anyway. It is vulnerable to electricity and has very high physical defense. It acts twice a turn and has three attacks. Death beam which has slayer on everyone and is Mystic. Its physical attack hits everyone and has slayer against everyone (also has a very small chance to debuff physical resistances). And its final move is Vortex which dispels.
My method here is very luck based. A more reliable way is to have Mokou, Aya, Byakuren, Alice, and Patchouli in Hyper Library formation. First turn, have Aya make everyone act first. Mokou casts the single target self res on Alice. Byakuren cast Spell Focus on Patchouli. Patchouli just spam her single target Electric spell. Make sure to have Alice equiped with a number of Electric items up her regen as much as possible. Give her either the Aegis Shield or a shield that prevents slayer. Give her as much physical/piercing/mystic reduction as possible. Adjust as necessary. Have Alice cover Patch every turn and hope for the best. If set right, Alice will take all the hits and regen faster than it deals damage to her.
King Flayer:
Knows Meteor and other moves. Doesn't matter though. Just Instant Death him. XD
