Favour of the weave

Beginning at 7th level, ancient magic lies so heavily upon you that it forms an eldritch ward. You and friendly creatures within 10 feet of you have resistance to damage from spells.

At 18th level, the range of this aura increases to 30 feet.

Arcane Reflection

Starting at 15th level, You’ve learned how to magically chastise anyone who dares cast unwanted spells at you and your wards. Whenever you or a creature you can see within 30 feet of you succeeds on a saving throw against a spell, you can use your reaction to deal 2d8 + your Charisma modifier force damage to the spellcaster.

Elder Guardian

At 20th level, you can assume the form of an ancient force of nature, taking on an appearance you choose. For example, your skin might turn green or take on a dragon-like texture, your hair might become golden or flame-like, or you might hover off the ground or glow with pure energy.

Using your action, you undergo a transformation. For 1 minute, you gain the following benefits:

• At the start of each of your turns, you regain 10 hit points.
• Whenever you cast a paladin spell that has a casting time of 1 action, you can cast it using a bonus action instead.
• Enemy creatures within 20 feet of you have disadvantage on saving throws against your paladin spells and Channel Divinity options.

Once you use this feature, you can’t use it again until you finish a long rest.
