"Double Cast"

[ManaKing]

i was thinking se could tweak it to absorb our own spells, or spells cast on us by pt members.

You shouldn't have to tweak it, Runic worked on all magic. Yours, your allies, your enemies. That would be party of the JA. If your BLM is casting AM and the mob or your party members cast something else, than you don't get the desired affect.
