itemcollection VS inventory-plus

For DND5e, there's a couple options. Item Containers and Inventory+. Both work on v9, neither have been updated for v10. I believe Item Containers will work on it, but Inventory+ won't. Inventory+ has a new repo for v10 that hasn't started work yet if you want to track that. (I do, it's the better option for me.)

Inventory+ and Item collections seem to be the only two choices currently available, and while both could be worked into a useable form, neither plays nice with the tidy5e sheets that I've come to know and love.

Item Collection

you can use the module Item Collection to create containers in your players sheet, it adds also configuration to the container item about how to handle its capacity, max weight, actual item weight (for bags of holding and such where the contained items weight zero) and so on.

This is what you are after - create all type of containers and bags. You can set the fixed weight and anything you put in it wont change the overall weight on your character. Its great. https://foundryvtt.com/packages/itemcollection

I believe the Item Collection module may be what you're looking for. Make sure to check out the GitHubfor additional information.

Thanks for pointing that one out. I think I'll keep an eye on it as it matures. Note this warning from the readme:

try inventory+ with that you can add extra inventory category in your character sheet and set them up for example as a bag of holding (the bag accept only 500lb of stuff, weights 15lb itself but wont add the items weight to the character) or wathever you want.

module inventory+ can do that.
