As an action, you can grow larger or smaller for the duration. Everything you are wearing and carrying changes size with you. Any item dropped by returns to normal size at once.
Enlarge. Your size doubles in all dimensions, and your weight is multiplied by eight. This growth increases your size by one category—from Medium to Large, for example. If there isn’t enough room for you to double your size, you attain the maximum possible size in the space available. Until the spell ends, you have advantage on Athletics and Brawn checks and any weapon you wield grows to match your new size, dealing 1d6 extra damage.
Reduce. Your size is halved in all dimensions, and your weight is reduced to one-eighth of normal. This reduction decreases your size by one category—from Medium to Small, for example. Until the spell ends, you have disadvantage on Athletics and Brawn checks and any weapon you wield shrinks to match your new size, dealing 1d6 less damage (this can’t reduce the damage below 1).
You can increase the damage by 1d6 for each additional mana expended.
You can expend 1 additional mana so a creature you touch grows larger or smaller instead. You can target one additional creature for each additional mana expended.
You can expend 1 additional mana to grow larger or smaller by one additional size.
Enlarge. You gain 10 temporary health and your reach increases by 1 meter.
Reduce. You have advantage on Stealth checks.
