When a revolver is loaded, it holds up to 6 bullets. The revolver only needs to be loaded after all of its ammunition has been fired. Loading a revolver (which holds 6 bullets) requires an action. A revolver can be used to make one ranged attack per bullet loaded into it.

This crossbow has a large winding wheel affixed to its drawstring which feeds into extra machinery along the stock that catches and pulls the string back again after it is fired. Winding a ratcheting crossbow for a single bolt requires a bonus action or action, and it can be wound to prepare two bolts. Masterwork ratcheting crossbows can be prepared to fire up to four bolts, or be constructed smaller (with statistics like a hand crossbow).

When this weapon is used to make an attack roll with advantage, the attack becomes a critical hit if both d20 rolls would result in a hit. When this weapon is used to make an attack roll with disadvantage and only one attack roll would result in a hit, you instead deal 1d4 piercing damage (adding no bonuses to damage from ability score modifiers or enchantments)

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.

At a glance this item seems to be perfectly typical, but it conceals a spring-loaded blade deployed by pressing a switch when it is used to make an attack. A creature observing it only realizes that the item is a weapon with a DC 15 Investigation check (made with disadvantage if the weapon is being worn at the time and not deployed). Once deployed, a bonus action is required to resheathe the blade. 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.

A spear-thrower can be used to increase the effectiveness of a javelin, spear, or trident. A weapon thrown in this manner deals an additional 1d6 damage when the target is within its normal range.

You have disadvantage when you use a lance to attack a target within 5 feet of you. If you are not mounted, you must use two hands to wield the lance.
