Boon of Growth/Shrink

When you pick this boon, pick one of the following options:

Growth: The target's size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category-- from Medium to Large, for example. The target's weapons also grow to match its new size. While these weapons are enlarged, the target's attacks with them deal 1d4 extra damage.

Shrunk: The target's size is halved in all dimensions, and its weight is reduced to one-eighth of normal. This reduction decreases its size by one category--from Medium to Small, for example. Attacks against the target must roll a d4 and subtract the number rolled from the attack roll

Size cannot increase or decrease past Huge or Tiny.
