[Feedback] Grapes of Wrath Changes

I think that the grapes of wrath need to be changed because most of the time it either hits nothing and be useless or doesn’t attack the right zombie so here are some changes I think should be added to make it balanced but better and also some things in general to benefit grapes of wrath
