Module:Item table

Module documentation[view] [edit] [history] [purge]

This module depends on the following other modules:

• Module:No globals
• Module:Util
• Module:Cargo
• Module:Game
• Module:Item util
• Module:Item link
• Module:Skill link
• Module:Item table/config

The item module provides functionality for creating item tables.

Implemented templates

This module implements the following templates:

• {{Item table}}
• {{Drop enabled item table}}
• {{Drop enabled base item table}}
• {{Drop enabled unique item table}}
• {{Gem table}}
• {{Drop enabled gem table}}

The above documentation is transcluded from Module:Item table/doc. (edit | history)
Editors can experiment in this module's sandbox (create | mirror) and testcases (create) pages.
