Split Concentration

As a master of magic, this feat enables you to maintain concentration on multiple magical energies simultaneously, significantly enhancing your spellcasting ability.

Benefit: Upon acquiring this feat for the first time, you gain the ability to concentrate on two spells at the same time. Each time you take this feat thereafter, you can concentrate on one additional spell.

Drawback: Concentrating on multiple spells decreases the potency of your spells. Specifically, the spell save DC for each spell you're concentrating on is reduced by 2 for each spell beyond the first. Note that this reduction only applies to the spells you are currently concentrating on, not to any other spells you cast.

Concentration Checks: If you take damage while maintaining concentration on multiple spells, you must make a separate concentration saving throw for each spell. The DC for these checks is individually based on the damage received. If you fall unconscious, you lose concentration on all spells you're currently maintaining.
