Wondrous Item

Rare Curse: It's full of spiders.

This bag has an interior space considerably larger than its outside dimensions, roughly 2 feet in diameter at the mouth and 4 feet deep. The bag can hold up to 500 pounds, not exceeding a volume of 64 cubic feet. The bag weighs 15 pounds, regardless of its contents.

However, Someone decided to fill it with spiders!

Retrieving a handful from the bag requires an action and a Wisdom (insanity) saving throw the first 3 times.

You can throw a handful of spiders at one creature you can see within 15ft. Make a Dexterity(Firearms or Improvised weapons) check contested by the target's Dexterity(Acrobatics) check.

If you succeed, The target must succeed on a DC 20 Wisdom saving throw or become frightened of you and the spiders until the spell ends. The frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. Undead, constructs, and aberrations are immune to this effect.

Cost: 450 gp
Weight: 15 lb
