Tales of the Valiant Players Guide (pg. 126)
Prerequisite: Access to 2nd-Circle Spell Slots
Your focus on the magic of life, death, and seeing beyond grants you these benefits:
• When you succeed on a death save, you can expend a spell slot of 2nd circle or higher to regain a number of hit points equal to five times the circle of the expended spell slot. Once used, you can’t use this feature again until you finish a long rest.
• You learn one 1st-circle divination or necromancy spell from any source spell list. When you cast that spell, you can choose to expend 2 hit dice instead of a spell slot to cast it at its lowest circle.
A character can have only one focus talent.
