and that is just a few of the many many discussions on this topic.
Casters would very much appreciate a bag for their spell components and a case for their scrolls.
In the past, spell component bags, etc. were described as not possible due to the mechanics of a spell pulling components from inside a bag.
The new crafting system has demonstrated that this technology is now available - please use it to finally create this high demand item.
