Pffft.  Just throw Balagos at the party.  Then let's see the servant of Lathander do anything other than A) Run away screaming in terror or B)  Die a horrible and painful death.  

  For those that don't know who or what Balagos is, just follow this link:

Anyway...  Well, I see the problem as being more the Forsaker class than anything.  It's a very poorly designed class, and practically requires Forsakers to destroy magical items.  In fact, given the class, I sometimes wonder if anyone can truly roleplay it and not come into major conflict with other party members who use magic.  
I think the Forsakers requirement to destroy magic should be dropped, personally.  They're not a very tough class, especially later on.  A 20th level X vs a 20th level X/Forsaker will always win, simply because the magic that comes into play in later levels renders a Forsakers abilities, which were decent at lower levels, seem downright paltry in comparison.  
So I think dropping the requirement to destroy magic items doesn't really make the class unbalanced, and it also allows a Forsaker not to develop a blood hatred between fellow party members.
But enough about house rules.  Nice post, and I look forward to seeing who gets to die next.
