Arcane Sense

Your studies into the nature of magic have honed your arcane senses. As an action, you can sense magic anywhere within a 500 ft radius for 1 minute. You can do this a number of times equal to your intelligence modifier. This number resets after a long rest. 

You are only able to sense magic nearby and the general direction it’s coming from, but you cannot use this ability to sense what type of magic or its source.

You also have advantage on any active perception checks from magic-based sources.
