Disciple of Light is a heroic tier feat available to characters with a Wisdom score of 13 or higher.
When a character with the Disciple of Light feat spends a healing surge while bloodied, each ally within 5 squares gains 3 temporary hit points. If the character is level 11 to 20, each ally gains 5 temporary hit points instead. If the character is level 21 or above, each ally gains 8 temporary hit points instead.[HotFL:312][HotFK:313]
Although the rulebooks' flavor text for Disciple of Light mentions Pelor, exclusive worship of that deity is not a prerequisite for the feat.
