Thanks. I'm not sure what I'm doing wrong either - I don't know if it's a case of game just hating me and giving me bad luck, or if there is something legitimately screwed up about my setup. LIFE typically opens with the Aqua Breath move followed by the Blue Light move, killing one party member and leaving the rest with about 10-20% health. If I'm lucky I can get a Shellga off before Aqua Breath hits, but I've had to S/L a bunch and can typically only Shellga about 1/4 times before Aqua Breath hits.
I tried the Poison/Sleep/Seal Evil/Kirin tactic, and it's the closest I've come to beating the boss. Poison LIFE, then either Sleep or Seal Evil, cast Kirin for group regen. Then repeat while blasting at the sleeping LIFE with 4* AJA spells. Lots of S/L'ing to get this set up - I probably spent 6 hours yesterday trying different variations of this and other tactics. Didn't win, and got pretty pissed off. Took some time to cool off overnight and tried again this morning with still no success.
Well in this case, I'll be missing Cloud's Memory Crystal.
