Thumb tacks and sting shard are OP

Thumb tacks and sting shard both stay in the arena and can hit multiple enemies. If you upgrade them a few times and use the poison charm they do massive damage. They're great for those little enemy challenge rooms and absolutely melted beastfly, judge, and cogwork dancers. Use thumb tacks for enemies on the ground and sting shard for flying. I noticed a lot of people are really struggling especially with beastfly but I think we're sleeping on the red tools...
