Boon Point Cost: 2
Prerequisite: Caster level 3rd and above
When you cast a spell, you may cast it at one spell level higher to increase the damage dice of that spell by one stage (1d4 becomes 1d6, 1d12 becomes 1d12 + 1d2, etc), for that casting. This increase in spell level does not contribute toward the At Higher Levels section of a spell.
You may use this boon a number of times on a single spell equal to half your proficiency bonus (rounded down).
