Increase either your Constitution or your Strength by 1

Rune of Loki: As a Bonus Action, you can cast the Enlarge/Reduce spell without expending a spell slot and it is cast on yourself at 5th level. The effects of the spell lasts for 1 minute and does not require concentration. You can cast this spell a number of times equal to your constitution modifier, however casting it multiple times in a row only extends the duration by 1 minute and does not stack the size and damage buffs. You get all uses back after you complete a long rest.
