Heh she did build a nice cleric, so I don't know.... "God mode" may be a fair assessment. :P  Touch of Healing although it can only be used on those under half hp and up until they are restored to half hp, can essentially keep people "half-alive" which isn't dead so, which means you can make your opponents dead.  Therefore I'm really not seeing much a problem here.  Aside from the fact that, true a wizard could just come along fireball everyone and kill the entire party...but hey if that happened.... it'd either be 1) the DM being a pure asshole or 2) extremely bad luck on a random encounter table, that a bunch of bad guys with a wizard shows up...or 3) a bit of both.... so my take on the whole thing, not likely unless 1 or 3.<br/><br/>
