Good archer idea for mords. I like the idea of all the aa lvls with the improved aa feats in mod. For gonds though pali dosen't work as well. they get blind fight instead of cleave pre epic but Sorc replaces bard for the pali archer for -4 ac and no umd. finaly a solid edge to a bg vs pali build
I would consider replacing 6 dex for cha for the 12 rd duration on sheild and might and +3 saves and unstopable damage as you suggested psalmzer. The trade off is that all your attacks are -3 not just the top one so over all damage dealt would be near eaqual either route. but every one should vary their builds somewhat hey?
