Moon Elf Resilience is an eladrin feat, but not available to those who obtained Sun Elf Grace. When the eladrin with this feat uses fey step while bloodied and no allies are within 5 squares, the adventurer may spend a healing surge as a free action. [FRPG:135] One character optimization guide rates this feat as poor as it's tricky to get it functioning, but mentions that it could be combined with Feral Fey Step for some classes.[Charop Warden]
