Casting Time: 10 minutes
Duration: instantaneous
Material Component: blood sacrifice

Through fair means or foul, you have discovered a way to summon demons without the use of spells. 

As part of the ritual, you must designate one demon type. The demon gains a spell save to avoid being summoned. If you speak the true name of a demon as part of casting this ritual you may attempt to summon that specific demon. In this instance the save to avoid being summoned is made at disadvantage.

Without other means of protection and control, a demon summoned to you via this ritual alone is not bound to and will probably not be friendly towards.
