A small 4 inch tube made of woven grasses and metals.

If used by one creature: Fail a DC 13 Dex save (or voluntarily fail) to activate the finger trap by holding it between your two index fingers. Then succeed on a DC (20- Int Score) check to be able to escape. If another creature is proficient with Int saves, they can use the help action to make the DC to escape equal 12. If used by 2 creatures: the enemy must make a DC 13 Dex save against being trapped. To escape, the winner must succeed on a contested Int check against the other creature. Every time you attempt the check and fail, add one more d20 of disadvantage.
