In Magic 3.2 Ring of Blessings was removed, along with the CAST GROUP/AREA for the six affected spells. I found the release notes lacking, so I thought I'd mention the following, especially since I've heard of a few clerics still holding onto the Group Supporter and Area Casting feats since the change.

"Group Spell Changes: Ring of Blessings and HYH-Uncurse have been removed, and Mass Rejuvenation is once again its own spell."

What I've found this means:

* Minor Physical Protection and Major Physical protection can not be cast on others.
* Protection From Evil, Bless, and Soul Shield can be cast on others, but can no longer be CAST GROUP or CAST AREA.
* The effect of Bless is reduced by half (maximum 200 strikes), however, this can be mitigated with the Team Supporter feat (maximum 400 strikes).
* The effect of Soul Shield does not appear to be diminished when cast on others.

The Group Supporter and Area Casting feats appear to have no affect on any of the six above spells spells.
