With the 1.10 patch two new craftable bag types will be available specifically for holding items related to either herbalism or enchanting. Tailors will be able to try their hand at crafting these new bags as the recipes will be found throughout the world. These new specialty bags will function similarly to how a normal bag would, but with the restriction of holding only herbs or enchanting supplies. The recipes will be made available for crafting these bags in various sizes, the high end of each type being 24 slots.
Seems the shard bags weren't the only bag expansion planned, which is nice. Shame there's no leather one mentioned, though honestly all I need is for them to up the max stack size of rugged hides from 5 to 10 (or 20 tbh ).
basically we carry pictures of george bush, westlife, crazy frog and a Rage Against the Machine CD in this bag and use them when we need an extra boost
