Fighter: Knight Archetype Inspiring Charge "You gain an expertise die on this attack. Until the end of your next turn, attacks made by you or allies within 10 feet gain an expertise die."
Fighter: Sharpshooter Archetype Focus Shot "Once per turn, whenever you take the Attack action and are able to make multiple ranged attacks you may forgo one of those ranged attacks
to turn one of your remaining attacks into a Focus Shot. When you make a Focus Shot choose one of the following options and make a ranged weapon attack. You gain an expertise die on the attack, "
Marshal: Mark Foe "You can use a bonus action to choose a creature you can see within 30 feet. Until the start of your next turn, creatures able to hear or see you gain an expertise die on attacks made
against that creature."
Marshal: Legendary Commander Commander’s Expertise "Whenever a creature uses your Commanding Presence to make an attack or use a combat maneuver, it gains an expertise die. "
Marshal: Daring Commander Archetype Risky Tactics Risky Foray "Until the start of its next turn, your ally gains an expertise die on melee weapon attack rolls, and creatures gain an expertise die on melee weapon attack rolls against it."
Equipment:
Assassin's Gauntlet/Boot Dagger: "You gain an expertise die on your attack roll when you deploy this weapon as part of an attack against a target that is unaware you have it."
Sword Pistol: "When this weapon is used to hit a target with a melee weapon attack, you can use your reaction to fire the gun in the handle, gaining a 1d6 expertise die on an immediate ranged weapon attack against the same target."
