You have been bestowed the gift of the 'Rage of the Arcane' by The Mother of All Magic herself. It is said, this is the remnants in the Weave of Mystra's rage at Karsus, moments before she placed the ban on magic, withholding High Magic from those who could follow Karsus' Folly and causing the Weave to tear.
Thrice times per long rest, you can channel the Rage from Mystra herself as a bonus action, which lasts for 1 minute or until you decide to stop raging. However, it ends early if you spend a turn without attacking or taking damage. It also ends if you are knocked unconscious. When you rage, you gain the following benefits:
- All damage caused by your spells has an extra 1d6 of force damage to it.
- You have advantage on Intelligence (Arcana) checks.
- You automatically pass any Concentration checks triggered by taking damage.
However, after you rage for the second time in a day you receive a level of Exhaustion.
After the Third and Final time your Rage has ended, due to the overwhelming influence from the Weave, you are knocked unconscious suffering 4d6 Force damage from the Weave itself. Due to this, all those around you within a 60 feet range, must make a Dexterity saving throw against your spell save DC or be flung 40 feet away, knocked prone and suffer 2d6 thunder damage. If they Succeed they only suffer half the damage and manage to land on their feet, but are stunned for a round.
If Detect Magic is used to witness this event, the person is Blinded for 1d6 days, due to the Weave righting itself and releasing the Rage back into the natural magic of the Prime Material Plane.
