This has been hinted around at in some other threads, but what's the definitive answer?
Player's Handbook- page 88:
Vow of Enmity. As a bonus action, you can utter a vow of enmity against a creature you can see within 10 feet of you, usin your Channel Divinity. You gain advantage on attack rolls against the creature for 1 minute or until it drops to 0 hit points or falls unconscious.
Player's Handbook- page 96:
Sneak Attack. Beginning at 1st level, you know how to strike subtly and exploit a foe's distraction. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon."
So (keeping it simple), if a level 3 Vengeance Paladin/Level 1 Rogue who is using a Scimitar (Finesse Weapon) has VoE on his target, can he add sneak attack to his damage roll once per round without resorting to trying to hide or use stealth?
