Sage/7th

Sanctified Body

At 9th level, the divine magic that flows from you has begun to enhance your body. You have advantage on any Constitution saving throw made to avoid exhaustion.

Great Sacrifice

Starting from 10th level, when you use your Sacrifice feature you can expend multiple Heart Containers at once. For each expended after the first, overpower the spell by 2 points. For example sacrificing 3 Heart Containers to cast life would cast it as a 5-point spell.

Sacrificing many Heart Containers at once enables you to cast these spells at a higher power than you otherwise could with spell slots.
