I think it's about time some of these were looked at, to improve scaling in later levels & make them more useful class features overall.
Bladesworn Transformation: You are a devoted follower of the Lord of Blades, and your faith has been rewarded. Activate this ability to attempt to become a juggernaut of destruction for 24 seconds plus 6 seconds per Religious Lore feat you have.
While transformed, you have a +4 Profane bonus to Strength, +4 natural armor bonus to AC, a +4 profane bonus on damage rolls, +10 enhancement bonus to Will saves against mind affecting magic, and proficiency in all simple and martial weapons. Your base attack bonus equals your level. You lose your spellcasting ability. You have immunity to critical hits and sneak attacks, but cannot be healed by healing spells.
It's a nice buff in lower levels when you can chug a repair potion, but the immunity to healing magic plus losing your spellcasting means it can actually make you a burden to the party. I suggest amending the STR, AC & damage bonuses to +1 per 2 religious lore feats then also add +1 MRR, PRR & repair amplification per religious lore feat & have repair moderate damage cast on yourself when damaged... it still has some risks but will scale a lot better in higher & epic levels.
Silver Flame Exorcism: You are a devoted follower of the Silver Flame, and your faith has been rewarded. Activate this ability to attempt to exorcise an extraplanar creature, which is entirely consumed in holy fire on a failed Will save or savagely burned by the light of the Silver Flame. A successful Fortitude save reduces the damage to half. The Save DC for this ability is 10 + Cleric Level + Charisma Modifier. Cooldown: 10 minutes.
I honestly don't know anyone who uses this except at very early levels where enemies might actually fail the save - and only once per 10mins? seriously lame. IMO this should be replaced with an activated ability that adds the banishing property (instakill on vorpal plus bane damage on-hit to extraplanar creatures) to your equipped weapon for 24sec plus 6sec per religious lore feat - it'd keep the same flavour of being for fighting against extraplanar enemies while actually being useful.
Vulkoor's Avatar: Duration: 10 minutes You are a devoted follower of Vulkoor, and your faith has been rewarded. Activate this ability to ask Vulkoor to send one of his servants to destroy your enemies.
Another one that's almost worthless much beyond the time it's introduced & therefore another one to be completely replaced; my suggestion is an activated ability that grants poison damage on-hit (similar to ninja poison so it stacks as a DoT, but on any hit, limited to once per second) & 3 points of poison damage resistance per 2 religious lore feats, +1 to saves vs. poison for every religious lore feat & a no-save, 6 sec paralysing effect on vorpal hits, standard duration of 24sec plus 6sec per religious lore feat. Essentially, instead of summoning an avatar of vulkoor you're imbued with some of the powers of one
