Double Spear

Momentum: 1d10

Double: A two-handed, double weapon functions as two light weapons, one in each hand, for two-weapon fighting purposes. If a double weapon has the reach property, you can use only one of these properties during the same turn.

Momentum: Momentum weapons allow you to deliver devastating attacks as part of rapid movement. When you hit a creature with a momentum weapon after you moved 20 feet or more in a straight line during the same turn, upgrade the damage dice to the weapon's momentum dice value.

Monk: A monk gains proficiency with advanced monk weapons at 5th level.

Set: You can use a bonus action on your turn to prepare, or "set," a set weapon against a foe moving toward you. A weapon becomes unset if you move or take any action after setting it. If a target enters your reach while you have the weapon set, you can use your reaction to make a melee attack with the set weapon against that target. If you hit, and your target moved 20 feet or more toward you before the attack, you can roll one of the weapon's damage dice one additional time and add it to the damage total.

Two-Handed: This weapon requires two hands to use. This property is relevant only when you attack with the weapon, not when you simply hold it.
