Large Domain

God of Large

Size Matters Not

Starting when you choose this domain at 1st level, when you damage a creature with an attack or a spell and the creature’s size is different than yours, you can cause the attack or spell to deal extra damage to the creature equal to your proficiency bonus. You can use this feature a number of times equal to your Wisdom modifier (a minimum of once). You regain all expended uses when you finish a long rest.

Channel Divinity: Blessing of Large/Curse of Small

Starting at 2nd level, you can use your Channel Divinity to alter the size of a creature or object.

As an action, you cast the Enlarge/Reduce spell, which does not require concentration and lasts for the duration unless dismissed as a bonus action. 

Superior Blessing/Curse

Starting at 6th level, you can use your spell slots to fuel your Channel Divinity: Blessing of Large/Curse of Small. Additionally, you alter the size of multiple creatures and/or objects at the same time.

You may expend a spell slot of 2nd level or higher instead of expending a use of Channel Divinity: Blessing of Large/Curse of Small to cast Enlarge/Reduce, requiring no concentration and lasting for the duration unless dismissed early as a bonus action. The maximum number of creatures you can affect with this ability at once is equal to your proficiency bonus, and when you use a bonus action to end the effect early on one creature, you can end this effect early on any number of them. 

Size Matters Not (Improved)

When you reach 8th level in this class, you regain all expended uses of Size Matters Not when you finish a short rest.

Size Matters Not (Superior)

When you reach 17th level in this class, you can use your Size Matters Not ability an unlimited number of times.
