Specifically I'm trying to add the new dark knight abilities from Wotl to the PSX version. Unfortunately there doesn't seem to be a formula that fits the desired effect. Has anyone done this already or are their any ASM hacks for a formula like this?
The Worker 8 skills use a "damage self to cause damage" formula. Ramza's Chant uses a "damage self to heal" formula. Between the two of those and Gaffgarion's skills, you should be able to put together a perfectly functional DK skillset.
Oh I completely forgot about worker 8's abilities! Thanks for the help.
