I want to make an item that reduces the wearers speed while he is holding it, but that also stacks with Endurance Aura, so I can't use that as a base. The only item ability that effects speed is the Item Movement Speed Bonus, but that only increases speed by a set number such as 60 or 100, it doesn't accept %s or negative numbers. Is there any item ability I could use to give my unit decreased speed? Preferably not based on Endurance Aura, as I stated it wouldn't stack with other Heroes who actually use skills based off of that Aura.
