Dual Focus

General Feat (Prerequisite: Level 4+, Spellcasting feature, Proficiency in Constitution saving throws or the War Caster feat)

You have trained your mind to maintain more than one arcane thread at a time, though at great risk to yourself.

• You may attempt to concentrate on two concentration spells at once.

• When you do so, you must immediately make a Constitution saving throw (DC 10 + the level of the higher-level spell). On a failure, one of the spells ends (your choice).

• Whenever you take damage while concentrating on two spells, you must make a separate concentration saving throw for each spell.

• If you fail any concentration saving throw while maintaining two spells, both spells end immediately.

• You cannot maintain concentration on two spells that total combined level exceed your proficiency bonus. For example, at level 12 (PB +4), you can maintain concentration on a 3th-level spell alongside another 1st-level spell, but not a 2nd-level spell and 3rd-level spell.

• You may use this feat a number of times equal to your proficiency bonus per long rest.
