So I made them all stronger. Some of the new strengths will probably be a little overpowered for brand new characters or those who are still at a low level, but will quickly even out as you get stronger and are definitely not as strong as the best custom things you can craft if you choose to pursue enchanting to any serious degree.
In effort to not change the overall feel of each divine blessing, I did not add extra bonuses, but rather simply increased the potency of whatever bonus each amulet already had, with two exceptions, namely the amulets of Arkay and Kynareth respectively.
The changes are:
Akatosh: Upped magic regen to 50%.
Arkay: Changed fortify health into health regen at 50%.
Dibella: Upped fortify persuasion to 25 points.
Julianos: Upped fortify magicka to 50 points.
Kynareth: Changed fortify stamina into stamina regen at 50%.
Mara: Upped fortify restoration to 25 points.
Stendarr: Upped fortify block to 25 points.
Talos: Upped fortify shouts to .50 points (50% cooldown instead of vanilla 20%).
Zenithar: Upped fortify barter to 25 points.
Installation: Drop the esp file in your data folder and make sure it's checked active in your modlist.
Uninstallation: Delete the esp.
Compatibility: Should work with anything that doesn't alter the religious amulet enchantments.
