Module:Common

Documentation for this module may be created at Module:Common/doc

-- This module contains common functions which interact with or interpret game data
-- in some form. Functions here may be applicable to various aspects of the game
-- (e.g. monsters, shop, dungeons, pets, items, and so on) and are contained here
-- to avoid loops when requiring modules.

-- Any functions which have no reliance upon, or relevance to game data are better suited
-- for [[Module:Shared]].

-- This module should _never_ require other modules which rely upon [[Module:GameData]]
