(General)
In even the fiercest battles, you risk life and limb to save your allies.
Prerequisites
You must successfully cast a conjuration (healing) spell on an ally after being hit by an attack of opportunity, or have the Battle, Chaplain, or Healed background.
Benefit
When attempting a concentration check caused by receiving damage (including ongoing damage), you reduce the damage taken by 50% for the purposes of determining the concentration check DC.
Goal
Over time, provoke at least 20 attacks of opportunity for casting conjuration (healing) spells on allies. These spells don't have to succeed to count.
Completion Benefit
You automatically succeed at concentration checks for conjuration (healing) spells caused by taking damage.
