Question

i know it will reduce the HP by 1\16 at a turn but is there any use to that ?

Comments

it reduces by 1/8 and heals 1/16 for the poison type

Answer 1

No, there isn't, unless you Trick or Switcheroo it away on a non-poison Pokemon. Black Sludge is to heal poison types only, so trickers get a bad item from tricking.

Hope This Helped :D

If held by a non poison type it damages the pokemon holding it

Answer 2

You can utilize trick/switcheroo onto a non poison type enemy. Otherwise, not so much use
