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.
