Anton's got 18 gold, which is enough to buy him Leather. Plus his shield that'd kick his AC to 13 out-of-combat. Definitely manageable if he can't manage to suit-up in time.
I should spell out the feats that he has, so you're all aware.
Healing Devotion allows as a standard action to spend a turn attempt in order to give the character fast healing for one minute. I think at our level it would be fast healing 1, but it goes up to 2 at 5th level, 3 at 10th, etc.
Touch of Healing allows as a standard action the ability to heal 3 points of damage per level of the highest-level healing spell you have available to cast. So essentially if I have a CMW memorized I could heal 6 damage, for free. The caveat is you can only bring someone to half their hitpoints by using this method.
Augment Healing gives a +2 bonus on healing per spell level of the healing spell cast. We're all familiar with that one.
So the hope is that Anton can keep the group well healed with minimum spells cast.
