I seem to have found a problem with modified monsters reverting to the default resistances of their archetype. In addition, a few other things change as well. I'm not sure, but this seems to be limited to color spray. After taking damage from it monsters sometimes change resistances. The easiest way to replicate this seems to be to use a default archetype, give it a few immunities and a ton of hp so color spray won't kill it flat out. Dump the object to check the resistances (this also seems a bit funny, I often have to fiddle w/ resistances a bit before I find a combination that will actually modify from the default archetype). Zap the monster a few times with color spray until it causes damage, then dump it again and check the resistances. This step may have to be repeated a few times. johnny PGP Public Key available from: http://www.keyserver.net:11371/pks/lookup?op=get&search=0x17BF1DD3
