Question is what makes PM in undead form so uber and good for the success of the party that Cleric or FvS would bother with meming extra spell and casting that spell on one single PM in the party?
Undead form sounds cool, but is it must have or atlest advantage in any give quest?
No-heal part of undead form sounds like that WF feat that grants 100% fort but no cure/heal. Are there any WFs that have that feat? Maybe some did, but I bet most are 'dead' now
