Drizlash's Chelicerae

 This longbow is pieced together with jagged and chitinous components. It is unpleasant to touch, and seems to squirm slightly, when held in your hands.

This weapon has one charge, which resets upon short rest.

 You have a +2 bonus to attack and damage rolls made with this magic weapon.

Webshot. When making an attack, you may consume the charge on this weapon to also cast  web at the same target. The spell save DC is 14 for dodging (Dexterity) or breaking free (Strength) of the web.  

Skittering Spawn of Drizlash.  This weapon has the power to summon a swarm of insects (spiders).  The swarm enters initiative and is under control of the DM.  After 1 hour, the swarm dissipates.

 When scoring a critical hit, in addition to critical damage, the swarm appears at the site of impact.   

 When scoring a critical miss, in addition to missing the attack, the swarm bursts fourth from the weapon itself.

Drizlash's Hunger Pangs. While attuned to this weapon, you become disinterested in all food that isn't meat or insects.
When you take a short or long rest and you have not consumed least one insect or similar meat, make a DC 13 Constitution saving throw, taking 2d6 psychic damage, or half as much on save. 

Proficiency with a Longbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
