The others just passed, actually!
Archsage Cloak, for some reason, was using the wrong internal name for Gravity amp. Both this and the Evil Eye Jewel's Burn timer are easily fixed; while there's only a few cases the latter might matter, there is an enemy that can hit 16 times in one turn, so it'd be better to take 7 Burn ticks than 10 Burn ticks.
Aeternator's AI does call all six Barrier Shifts, but I actually forgot to give him resistance to the Burn, Chill or Soften states, because he absorbs the elements. This is a minor oversight that should be easy enough to fix. He doesn't actually react to Amps in any meaningful way.
