I don't think either of the abilities lost for Awakened Champion is that painful in exchange for manifesting, but I don't think much of Psychic Strike either and that's what's lost by Gifted Blade so that doesn't matter.

Giving Zealot level -2 manifesting at level 3 when you replace a 4th level is a bit odd

Having to spend resources to get Zealous Fury on a Zealot seems weird. Not unbalanced or anything, just weird. Would be less weird if it wasn't the only new conviction open to them.

Speaking of Zealous Fury, does it reduce the penalty on doubling up via a Fortuitous (ACG) weapon?
