You exhort a fiend to attack a distant foe. After the offering is made, make a spell attack roll to determine which fiend is summoned:

d20	Result	CR
1-4	Sending fails	-
5-8	Wind Demon, or Quasit	1-2
9-12	Rattok Demon, or Bearded Devil	3-4
13-16	Lesser Lunar Devil, or Vrock	4-6
17-20	Lunar Devil, or Hezrou	8
21+	Alnaar, or Horned Devil	9-11

Once summoned, you must compel the fiend to seek out a particular creature you choose that is on the same plane of existence as you by making a DC 10 Charisma (Persuasion) check. On a success, the fiend slinks off to its target, usually but not always by night. On a failure, the fiend refuses, and the offering and the bowl are consumed in the casting.   The conjured fiend may find that the target is warded or inaccessible or simply difficult to find (whether because of invisibility or some other reason). In this case, you must make a DC 15 Charisma (Persuasion) check. On a success, the fiend returns and demands no further offering, reports its failure, and vanishes. On a failure, the fiend returns and demands another offering. If this is not immediately forthcoming, it attacks you.
