Okay just a couple of quick questions about a few more spell bugs I seem to have found...

1.Otiluke's Resiliant Sphere-I put it up around a Troll and he was still able to deal damage (albiet small amounts) to one of my characters as well as move around. I thought ORS stopped ALL movement and interaction with the outside world? Is this a known bug or is there a "reasonable explanation" for this? If it is a bug is there any way to fix it?

2. Okay, this is not a bug question but I figure better to ask here rather than a new thread...Is there any store in SoA where I can actually buy some of the better spells like Stoneskin (need for Haer'Dalis), Sequencers, Contingincies, ADHW, etc. If so where is this store and what chapter can I access it in?

1) Yes, I would imagine it to be a bug.
2) Adventure's mart should sell them.

AdventureMart, Spell merchant by Den of 7 Vales, Duergar camp at beginning of Underdark, Drow in Ust'Natha, and the merchants in Trademeet. All of these have a good selection though you might have to quest for ADHM and chain contingiences etc. Also there is a store in ToB that sells more spells than you can shake a stick at...
