Most High-Level Abilities available to clerics are quest-level spells, which are listed here. However, this page lists the comparatively-few abilities available to high-level clerics which are not quest level spells.
Note that this list assumes a full install of Talents of Faerun, excluding the 'new low-level abilities' component. If you have a partial install, your High-Level Ability system may differ from the one documented here in small ways.
The character's rapport with the divine has reached the stage where they can imbue water with a small part of that divine power, creating potions of healing and protection.

Antidote
Elixir of Health
Potion of Clarity
Potion of Extra Healing
Potion of Freedom
Potion of Healing
Potion of Regeneration
Potion of Superior Healing
