3rd                      detect magic, identify

5th                      silence, augury

Channel Divinity

At third level you gain the following channel divinity options, which amuses Ethy greatly:

Ethy's Defiance: "Did you spill my tequila? I think you spilt my tequila..." You use your channel divinity as a bonus action to gain the following benefits for the next minute: you may add your proficiency modifier in radiant damage to your melee weapon attacks and you gain +2 armour class for the duration, as you emit a glow of holy anger (dim light) in a five foot radius around you.

Holla' to the Lady: You hold your holy symbol (or drink) aloft and give Ethy the shoutout she deserves, possibly including reference to an enemies' genetalia. You may use a bonus action and a channel divinity to regain up to your proficiency modifier in spell levels. You may not gain more spell levels than your caster level normally allows, and may use this channel divinity option only once per long rest.

Ethy's Presence

Ethy's presence is more manifest around you, which is nice, as your magical ability grows with her proximity. Sometimes she can get a bit... chatty, though.

At seventh level you may add your charisma modifier to the damage you inflict with your divine smite feature.

You may also ask your goddess minor magical favours. This is represented by you gaining the ability to ritually cast your paladin spells with the ritual tag. You need not have prepared these spells beforehand, but should prepare for a ten minute chat with your goddess.

Expanded Magical Knowledge

At fifteenth level you may swap up to one spell from each spell level from your Oath of Magic feature with another of the same level from any spell list. This includes a fifth level spell, although you must wait until 17th level in this class before you can cast it, as normal. You also gain an attunement slot.

Defence of the Goddess

"You're using MY magic, against MY chosen? Good luck, moron." 

At twentieth level, once per long rest as a bonus action, you may call upon Ethy to grant you power over nearby magic:

For the next minute you utilize "Ethy's Defiance" without using your channel divinity option. Your "holy glow" becomes bright light in a twenty foot radius and dim light for a further twenty feet and;

Anytime a creature within 90 feet of you casts a spell or uses a magical ability, you can choose to have them make a concentration saving throw against your spell DC or the spell/ability fails. You may also force this saving throw at the end of a creature's turn if they are concentrating on a spell, unless they have already made a save against this feature this turn.
