This is SO fantastic for making keeping track of spell components easier. You can just drop these items in the wizard's laboratory, or in the apothecary shop. Great for campaigns where you want to strictly keep track of components.
A lot of crafting went into developing spells and their components by the creators of D&D. This resource of components that can be dropped into the inventory tab on your character sheet adds another layer of needed depth for spellcasters in Fantasy Grounds. Pick a new spell when you level up or find a spellbook and gather the appropriate corresponding components. Very convenient to see them listed in your inventory. Well worth it for players and DM's!
