Battle God

Impeccable technique

When you choose this archetype at 3rd level, you gain proficiency with two martial weapons of your choice. They have the finesse property for you.

You also gain an additional way to use your Sneak Attack; you don’t need advantage on the attack roll to use your Sneak Attack against a creature if you attack while using the weapons from this feature and you don’t have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you.

Provident Defenses

Starting at 3rd level, you gain medium armor proficiency. You do not get disadvantage on Dexterity (Stealth) checks from the armor, 

In addition, you can use the Ready action as a bonus action.

Opportunist

Starting at 9th level, you gain an additional reaction each round.

Scrollbound Sorcery

Beginning at 13th level, you can use your battle experience to cast magic. You can read any spell scroll, and can use your bonus action in order to cast the spell without expending the scroll. You still need to make an Intelligence (Arcana) of 10 + the spells level in order to cast the spell successfully, but it won't be expended either way. 

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

Foeslayer

Starting at 17th level, your weapon attacks score a critical hit on a roll of 18 or higher. You also have advantage on all opportunity attacks, and you can use a reaction to make a melee or ranged opportunity attack against an enemy within range that makes an attack against an allied creature.
