Consumables

Consumables are items such as potions or food that can be used.

Potions
Potions are usually used once, and will restore one or more resources. The DM can come up with their own potions if they like, anything to keep the game fun and interesting. Potions are free actions and can be used while grappled.

Food
I threw food into the game for fun. Food can be only be used out of combat as it takes a bit of time to eat it. Food when used out of combat will fully restore a player. Keep in mind players can usually try to rest at the spot if the DM permits (you might have a hard time resting while swimming or is being pelted by a blizzard) which limits food's usefulness. However it can also be used to avoid passing time, like if the party is in a forest full of werewolves at dusk and are looking to leave before dark.

Using the HUD
There is no current HUD command for items, you'll have to use the command line. Keep in mind to not add stats to anything that shouldn't be worn, as there's is no way for the system to differentiate between worn items and inventory. You can add an item by doing .addgear: Name, Desc, (opt)stats

Adding a potion might look like:

Roguie.addgear: Health Potion, A vial of red liquid.

If the player has multiple of the same potion, you'll want to put that in the description to save space. Also inventory are unique by name.

Roguie.addgear: Health Potion, 3 vials of red liquid.

Then if roguie drinks one potion:

Rogue.addgear: Health Potion, 2 vials of red liquid.
