Fighter/15th/Captain

Inspired Leader

As an experienced captain, you've learned not only to protect your allies, but feel inspired by their aid. Starting from 15th level, whenever a creature uses its action to Help you or restore your heart points, you gain 10 temporary heart points.

Aegis

Starting from 15th level, while a target is compelled to duel with you, all other creatures have advantage on all saving throws imposed by the compelled target.
