Knowledge Above All

You have trained your mind, and allowed yourself to manifest the realm of the All-Knowing. You gain the following feature:

You may concentrate on a number of spells equal to you highest Spell-casting abilityscore modifier. When you do this you take 1d4 Psychic Damage. You may cast non concentration spells without penalty as long as you have not used all the Modifier available to you. The damage you take as part of this feature ignores resistance and immunity, and does not require you to make a Constitution saving throw to maintain your concentration. All maximum hit point reductions from this feature are restored during your next long rest.
