Brennan’s Law

Brennan’s Law Grants you Arcane Overload.

You channel volatile arcane energy, entering a state of magical fury.

On your turn, you can enter Arcane Overload as a bonus action.

While in Arcane Overload, you gain the following benefits if you aren't wearing heavy armor:

• You have advantage on Intelligence checks and Intelligence saving throws.
• When you cast a spell, you gain a bonus to the damage roll that increases as you gain wizard levels, 1-8 +2 damage, 9-15 +3 damage, 16-20 +4 damage.
• You have resistance to elemental damage as well as magic damage.

You can not make a weapon attack while in Arcane Overload.

Your Arcane Overload lasts for 1 minute. It ends early if you are knocked unconscious. You can also end Arcane Overload on your turn as a bonus action.

You can use Arcane Overload twice per long rest at levels 1-2, three times at 3-5, four times at 6-11, five times at 12-16, six times at 17-19, and at level 20 you're always in Arcane Overload.
