Then that's beyond my abilities. Microsoft has abandoned Internet Explorer in favor of Edge - this means it doesn't have technologies that I need and these are not going to be implemented.

Some heroes will have ability to stack multiple inventory.
Shaman will have lots of potions and Ninja can have couple of shurikens.

There is no way you can stack a lot of items because that would render some players literally immortal.
