Junkkind

This specibus is initially empty. To fill it, you must use one item from your sylladexu. This takes one major action to accomplish.

Once you have a weapon, roll a 1d4 and a 1d10. This is your durability and the number of faces on your damage die. After 1d4 successful attacks, the will break, and you must fill the specibus again.

+DEX for to hit, and +STR to damage

Here's an example.

Roger has a Junkkind specibus. He decides to us a piece of paper as his weapon, and rolls a 2 for durability, and a 7 for hit dice. During a fight, he can successfully attack 2 times before the paper ceases to function, and rolls 1d7+STR for damage. After the paper breaks, Roger may expend a major action to apply another item from his sylladex to the specibus.
