Aphadon:

Taur Adar's Mercy: All units gain +1 Attack and Defense versus nations that have genocided, displaced, or otherwise treated the follows of Aphadon with cruelty. Resplendent God: Once per character, and by sacrificing a health state, you may form a Pact with either Taur Adar, or the Fire Father. This takes the form of the greater Pact, is free, and gains a bonus to the benevolence roll equal to the amount of pops you've converted to this religion in your lifetime (max +5).
