Path of Magical Focus

Some people are born with the ability to control magic. Most people are though to control this magic, others aren't. Whenever these kinds of people let emotions take over sometimes the magic will as well. You are the physical manifestation of the balance between magical chaos and control. You have learned to use your emotions to regulate the magic within.

Magic Awareness

When you choose this path at 3rd level, as an action, you can open your awareness to the presence of concentrated magic. Until the end of your next turn, you know the location of any spell or magic item within 60 feet of you that isn’t behind total cover. When you sense a spell, you learn which school of magic it belongs to.

 

You can use this feature a number of times equal to your proficiency bonus, and you regain all expended uses when you finish a long rest.

Magical Fury

You have learned to control the magic put forth by your emotions. You are able to cast spells using the new magic barbarian spell list. You can not cast these spells while raging.

Magical Rage

You are able to control your emotions while letting it go ramped. You are now able to cast spells while raging, but you have to make a concentration check of DC 15 to maintain your rage.

Magical Burst

You are able to unleash a surge of magical energy when you let your emotions go ramped. Starting at level 10, the magical energy roiling inside you sometimes erupts from you. When you enter your rage, roll on the Wild Magic table to determine the magical effect produced. These effects do not count as spells and are not effected by the magical rage feature.

If the effect requires a saving throw, the DC equals 8 + your proficiency bonus + your Constitution modifier.
