Author your first item

Items are the reward at the end of most loops, so they are a good place to start customizing. An item needs a slug that is unique on your channel, a name, and a rarity.

Item
slug:       storm-glass
name:       Storm Glass
rarity:     Legendary
consumable: no

Choose a rarity that means something

Rarity is cosmetic, but the ladder shapes how often an item drops once it is on a loot table. Reserve the top tiers for rewards you want to feel rare, and keep everyday finds lower on the ladder. The rarity page explains the full ladder.

Make it do something (optional)

Mark an item consumable if using it should have an effect, for example granting another item, rolling a table, or boosting the next fight. Leave it off for trophies and materials.

Pick the slug once and keep it: loot tables, shops, and flows all refer to the item by slug, so renaming the slug later breaks those references.
