Devout Warrior

Beginning at 3rd level, you can bless either yourself or another creature until the beginning of your next turn as a bonus action. Before the end of your next turn, the creature can make an additional attack with a weapon the next time the blessed creature makes an attack with a weapon.

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: War God’s Blessing

Beginning at 6th level, you can use you channel divinity to cast one of your domain spells as a reaction when another creature makes an attack within 30 feet of you. You cast the spell immediately before the triggering attack is rolled.

The triggering creature gains the benefit of the spell regardless of the spell’s normal range or target restrictions (e.g. you can spend a 1st level spell slot when you use this reaction to cast true strike on the triggering creature). For all purposes but who gains the benefit of the spell, you are the caster of the spell (meaning you must maintain concentration on the spell if it requires concentration, and the spell uses your spellcasting ability modifier and saving throw DC).

Guided Strike

Beginning at 10th level, the next attack you make after using your channel divinity scores a critical hit on a roll of 18, 19 or 20. You must make the attack before the end of your next turn.

Avatar of Battle

At 14th level, you gain resistance to bludgeoning, piercing, and slashing damage for 1 minute whenever you cast one of your domain spells.
