You’ll save additional inventory space with consumables stacking up to 200 in Dragonflight.
Consumables like Enchants, Gems, Phials, and Potions, will stack up to 200 in Dragonflight, allowing everyone to save even more Inventory space. Here’s a screenshot from Alpha where phials and potions stack to 200 in the backpack.
