As a DM I am asked about his optimization by one of my player who plays a Healer. I found the question interesting because as far as I know there is no relevant resource for divine caster than wear light or no armor.
Here is the rule:
Healers are proficient with all simple weapons and with light armor. Additionally, a healer who uses metal armor or any kind of shield is severely hampered. The armor of a healer is restricted by traditional oaths, not simply training. A healer knows how to wear light metal armor and could become proficient with medium or heavy armor, but wearing metal armor or bearing a shield would violate her oath and suppress her healer powers. Her ethos requires a certain vulnerability that allows her to more fully empathize with those in their care. A healer who uses prohibited armor is unable to cast healer spells or use any of her supernatural or spell-like class features while doing so and for 24 hours after the armor is taken off.
So my player can use light armor, but it must not be in metal (I also forbid blue ice since it would break the vulnerability oath the same way metal do). In my understanding, "certain vulnerability" is psychological: I feel vulnerable when what I wear is not made of a strong material.
I could of course have some NPC craft him a custom light armor. I already know about armor creation rules so I don't need your help here. On the other hand, since he have already WIS 24 I could advise him to wear no armor at all and use a monk's belt instead. But that would still leave its torso or body slot open for some vest or robe. Since this is a high level campaign where it will be possible to have very high dexterity scores, I think this is the best solution except if there exists in the books a specific armor with qualities especially fitted for a healer.
Acceptable answers are
- Any pre-crafted light armor listed in an (even exotic) official source that has a special property related to divine casters that you could not obtain by applying armor creation rules. Typically, emulate a feat but there are other possibiliti
- Any torso/body related item other than an armor that has a special property related to divine casters. Using item creation rules is possible here.
An example: gloves of the balanced hand (MIC 105) is a well know item that emulate a feat. It is a special item that you can find in a book, and as far as I know there is no item creation rule that explains how to create it. There are a lot of other items like that. Now I am looking for the same kind of thing for the torso/body slot with a special property (I don't impose a feat) which would suit a divine caster.
Another example: You probably know about the "Robe of the Archmagi"? I am looking for a "Robe of the Archpriest"
I believe that question about lists of objects are not exactly welcomed here, so if there are a lot of candidate items, just tell me where I should look. But if there was so much possibilities I believe I should have found them by myself already.
This is a tiers 4/tiers 5 level 15-20 campaign. Most resources are allowed, including dragon magazines but excluding psionics and material related to a very specific universe. Since I allow a lot of resources, I would rather avoid houseruling or using loopholes to get around the rules.
