Mythal Touched

Mythal Ward

If a spell attack hits you or you fail a saving throw against a spell, you can take a Reaction to roll on the Mythal-Touched Magic table to create a magical effect. If an effect requires a saving throw, the DC equals 8 plus the modifier of the ability increased by this feat and your Proficiency.

You can use this benefit a number of times equal to your Proficiency, and you regain all expended uses when you finish a Long Rest.

Mythal-Touched Magic

1d20	Effect
1-2	You and each creature within 15 feet of you make a Dexterity saving throw, taking Force damage equal to 1d8 times the level of the triggering spell on a failed save or half as much damage on a successful one.
3-7	You and the triggering spell's caster form a telepathic link for 1 hour.
8-10	Gravity is reversed in a 15-foot-radius, 60-foot-tall Cylinder [Area Of Effect] centered on you for 1 minute, per the Reverse Gravity spell.
11-13	You and the triggering spell's caster each make a Constitution saving throw. On a failed save, the creature has the Stunned condition until the end of its next turn.
14-17	You gain a +2 bonus to AC for 1 minute, potentially turning the triggering spell into a miss if it was a spell attack.
18-19	Any flammable, nonmagical object within 10 feet of the triggering spell's caster that isn't being worn or carried by another creature bursts into flame, takes 1d4 Fire damage, and is burning.
20	The triggering spell dissipates with no effect, and the action, Bonus Action, or Reaction used to cast it is wasted. If that spell was cast with a spell slot, the slot isn't expended.
