Uh-oh, it looks like the consensus is it is over powered. Damn.
Ok - a step prior to gaining the 1st Beneficence ability.....
Perhaps a change in general.....
1st: Instead of allowing a re-roll, it grants +2 save - must use prior to rolling save!
2nd: only effects saves, but now +4 save.
3rd: stays the same (sac spell to target extra folks)
That should weaken it!
Now, if the above is too good, then the alternate chain Benevolent, and the powers Mercy & Mantle are probably over the top too...
Benevolent
1st: take away dmg and save bonus
2nd: stays the same (sac spell to target extra folks)
3rd: sacrifice a spell to grants +1/2 spell level divine AC bonus
Mercy’s Gift: Acts as shield other - the user takes 1/2 the damage the target takes. - - - I'd change it to the name to Martyrs Sacrifice
Mantle of the Giver: I think this one isn't too powerful.....
