A devilbane priest has the following class features.
The cleric is proficient with all simple weapons, light armor, medium armor, heavy armor, shields (except tower shields), and the favored weapon of his deity.

At 1st level, when making Knowledge (planes) checks regarding demons, demonic cults, and their magic, the cleric gains a bonus on the check equal to half his class level (minimum +1) and can make these Knowledge skill checks untrained.
At 4th level and 8th level, the cleric gains a bonus feat.
