Working on a concept on soloing the weapons for the moment. One thought on Emerald is to only use 2 materias, get the characters hp to 9999 and keep on casting elixirs and rely on the air tame storm and lucky seven.
On ruby weapon I thought alot of counter attacks and hades+added effect could do it (would take time though), but apparently the paralysation on Ruby didn't want to work.
Oh yeah, the plan was to keep from using kotr. Otherwise I'd probably master kotr and linking it to hp absorb and mp absorb, use w-summon then mime over and over again.
