Zzrot Portal QoL change
So I haven't used this item a whole lot, but one of the more important changes I think the item needs is to show the max range over which the creatures will travel. Again, I haven't used it many times, but when I did, I would find that where I placed the portal, the creatures were dying before they arrived at the tower.
Now, since they still did detonate and deal damage to the minions, they weren't dealing damage to the tower, which would be the main reason I bought the item in the first place. Therefore, I think mousing over the item in your inventory should display the max range which the creatures will travel; it would make using this item much easier.
