Shield of the Divine
From Neverwinter Wiki
When you, or an ally within 30' of you takes damage, they receive a Heal Over Time from you, healing for 500% of your weapon damage over 10 seconds. Any ally cannot trigger this effect while already affected by Shield of the Divine. Additionally, Healing Word, Bastion of Health, and Divine Glow no longer directly heal allies and instead apply a Heal Over Time to affected allies for double that amount over 12 seconds.
