Paladin: 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

3rd-level paladin 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 that 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: 3rd level, once; 7th level, twice; and 15th level, thrice.
You regain all expended uses when you finish a long rest.

Martial Versatility

4th-level paladin feature

Whenever you reach a level in this class that grants the Ability Score Improvement feature, you can replace a fighting style you know with another fighting style available to paladins. This replacement represents a shift of focus in your martial practice.
