Amulet of Spell Multitasking

The Amulet made of an unknown purple-green metal from an Aberration realm. The Amulet is in the shape of a Mind Flayer head with a Jade diamond in the forehead.

The Amulet allows Spell Casters to have two Concentration active at the same time. If the spells have a bonus action, casters can use one bonus action for both spells at the same time. If Caster fails a Concentration saving throw, he looses both spells.

Cursed: Caster is Vulnerable Psychic damage while attune to Amulet. Caster takes 4d8 Psychic damage if Amulet is unatoned.
