Divination adept

Prerequisite: Spellcasting or pact magic feature

You have advanced your ability to call forth unforeseen knowledge.

You learn one divination cantrip of your choice from any class's spell list.

In addition, choose one 1st-level divination spell from any spell list. Using this feat, you can cast the spell once at its lowest level, and you must finish a long rest before you can cast it in this way again. You can also cast this spell using your regular spell slots.

Your spellcasting ability for these spells is the same as that of your own classes.

Furthermore you gain an ability named Twofold Focus. When casting a divination spell that requires concentration you can let your Twofold Focus take over the concentration for you allowing you to concentrate on a different spell. The second spell must be from a different school other than divination. 

If you are already concentrating on a spell other than that of the school of divination and you cast a divination spell that requires concentration your Twofold Focus will automatically take over concentration of the divination spell.

If your two spells grants contradicting effects the spell that you yourself is concentrating on will overpower that of the one being held by Twofold Focus.

If you roll a constitution saving throw in order to withhold your concentration while using the Twofold Focus feature the save automatically fails and you lose concentration on both of your spells.
