Mercenary's Pauldron (Patreon)

Wondrous item, uncommon (requires attunement)

This magic pauldron has 3 charges and regains all expended charges daily at dawn. You can use a bonus action while wearing the pauldron to expend 1 of its charges to divine its tactical insights, magically granting you advantage on the next weapon attack roll you make before the end of your next turn. On a hit, the attack deals an extra 1d6 damage of the weapon's type, and you gain that same amount of temporary hit points, which last until the end of your next turn.

"I'd sooner be a mercenary than a hero. Much longer life expectancy, same job requirements, and the pay is better. I'm not about to throw my life away for just anyone. Show me the gold and I'll give you my blood."
