Chuul's Sense

You have developed traits similar to those possessed by a chuul, granting you the following benefits:

Ability Score Improvement. Increase your Strength or Constitution by 1, to a maximum of 20.

Darkvision. You gain darkvision out to a range of 60 feet.

Magic Sense. You can sense the presence of magic within 60 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.

This sense can penetrate most barriers, but it is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt.
