Cleric: Optional Class Features

What are these?

The following list are class features that your dm may either allow you to have in addition to the features you gain from your class or they are options that might replace existing class features

Harness Divine Power

2nd-level cleric feature
You can expend a use of your Channel Divinity to fuel your spells. As a bonus action, you touch your holy symbol, utter a prayer, and regain one expended spell slot, the level of which can be no higher than half your proficiency bonus (rounded up). The number of times you can use this feature is based on the level you've reached in this class: 2nd level, once; 6th level, twice; and 18th level, thrice. 
Your regain all expended uses when you finish a long rest.

Cantrip Versatility

4th-level cleric feature

Whenever you reach a level in this class that grants the Ability Score Improvement feature, you can replace one cantrip you learned from this class's Spellcasting feature with another cantrip from the cleric spell list.

Blesse Strikes

8th-level cleric feature, which replaces the Divine Strike or Potent Spellcasting feature
You are blessed with divine might in battle. When a creature takes damage from one of your cantrips or weapon attacks, you can also deal 1d8 radiant damage to that creature. Once you deal this damage, you can't use this feature again until the start of your next turn.
