For effect 177 (Use EFF file), there is a limited selection of IDS's available. Would it be possible to enable all IDS's to be an option? Just as an example, if I wanted to filter an effect to only apply to Dynaheir, I would use NPC.IDS : DYNAHEIR. Her # within the IDS is already given (4), so I'm wondering if you can figure out and tell us the other IDS #'s.
Everything there is true, steam version or not. The few BGEE-exclusive engine fixes won't matter for 99.99% of the players, and PC modders unattached to Beamdog don't care, either. I'm still waiting on a reason to get it as there's tons of engine stuff that could greatly expand the mechanics possibilities.
