I may have made a mistake in giving the Devil of Caroc the soulbound item Steadfast, as its level 3 requires getting to 30 might.
The Devil starts with 13 base might, I can give it +3 from resting at Caed Nua, and +3 from one of the helms I found, bringing me to 19. From here, I can give myself +10 via the priest buff Champion's Boon. This brings me to a running total of 29.
Since the Devil can't eat food, use drugs, or drink potions, what can I do to get that extra point of might?
