Maybe this is old, but I couldn't find it on a search. Anyway, here's a random bit of trivia for NearInfinity for anyone who wants to turn a dual-classed character into a multi-classed character (i.e., make Immie into a half-elven mage-thief). Under "flags" check the "unknown 15" box. Without that box checked, characters default to dual-classed if the class combo is valid.

Really? I thought 15 was the 'been in party' flag. Bits 3-8 control single/dual/multi class status... Or at least according to the IESDP: http://iesdp.gibberlings3.net/ieformats/cre_v1.htm

Hmm, well, I could be wrong. But when I opened my unedited game, Immie didn't have 15 checked. She converted to multi from dual only when I checked 15, and I don't think I changed anything else. If that didn't do it, I have no idea what did. Any idea what made the switch? I'd like to be able to repeat it in the future.

You might have an older version of Near Infinity.
