Arcana Domain - Channel Divinity: Arcane Abjuration

Cleric 2, Cleric 5, Cleric 8, Cleric 11, Cleric 14, Cleric 17, Arcana Domain, Channel Divinity

Starting at 2nd level, you can use your Channel Divinity to abjure otherworldly creatures. As an action, you present your holy symbol, and one celestial, elemental, fey, or fiend of your choice that is within 30 feet of you must make a Wisdom saving throw, provided that the creature can see or hear you. If the creature fails its saving throw, it is turned for 1 minute or until it takes any damage.   A turned creature must spend its turns trying to move as far away from you as it can, and it can't willingly end its move in a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If there's nowhere to move, then the creature can use the Dodge action.   After you reach 5th level, when a creature fails its saving throw against your Arcane Abjuration feature, the creature is banished for 1 minute (as in the banishment spell, no concentration required) if it isn't on its plane of origin, and its challenge rating is at or below a certain threshold, as shown below.   Arcane Banishment | Cleric level | Banishes Creatures of CR... | |       5th        | 1/2 or lower                           | |       8th        | 1 or lower                              | |      11th       | 2 or lower                              | |      14th       | 3 or lower                              | |      17th       | 4 or lower                              |
