How to create item that gives move speed debuff and can stack

[emil23]

I tired many things, but i cant find the solution. i have a lot of items of same type and i want player to have less movement speed the more items he picks up. i tired to enable in gameplay contacts allow movement speed bonus stack but its broken doesnt help. i tired boots of speed but they dont work at all when they have negative values. wc3 auras doesnt stack they only do if its different move speed aura. but they must be same! as kind of item is same. i found on forum that someone said movement speed tornado aura will stack but it doesnt any idea?

Tornado aura does indeed stack but only different versions of it. So you have to create multiple copies of it or make a leveled one.
