Pathfinder Campaign Setting: Inner Sea Gods is the system that contains Evangelist.
Evangelist doesn't work for the align class aspect (at the very least with magus), which is pretty much the whole deal. It doesn't add class features correctly (such as magus arcana), it also doesn't do spell progression correctly for giving you new spell levels and spells for day.
It also gives Divine Boons if you look in the character sheet but it asks you to select boons in the things to be done tab (also I suppose it may be giving it via the feat so maybe it should be checked).
It gives you spiritual form on the character sheet nothing wrong there, I guess it would be convenient to add it to the temporary bonuses, but that's more suggestion than bug.

You wanted this for a Magus?
yeah, one of the campaigns i'm in decided to keep going on till 30. and i never planned on multiclassing cause theres honestly not really any classes that help magus in a real way so i found out about evangelist and the fact that in a game where 20 isn't the max it has literally no downside. so >.> that took care of 1 lvl worth of what i would do next.
Well, I can't easily support the casting aspects yet. But I can grant you an increase.
I've just tried levelling up Evangelist as an option for next few levels for my character, but align class only displays 3 choices available (barbarian, cleric and magus) none of which are valid for the character (bard with a bloodrager dip).
