Boon Point Cost: 2
Prerequisite: Sorcerer level 3rd and above
When you cast a spell, you may expend 2 sorcery points to increase the damage dice of that spell by one stage (1d4 becomes 1d6, 1d12 becomes 1d12 + 1d2, etc), for that casting.
You may use this boon a number of times on a single spell equal to half your proficiency bonus (rounded down).
