Lua adds a fully functional economy and levelling system, with its’ primary currency unit being the ‘coin’. Coins can be used to purchase tradable items. (Note that coins have no real world value.) Both coins and levelling experience are obtainable through sending messages that are visible to the bot.
Lua’s levelling system includes a unique prestige mechanic, where users can reset their level to 0 after reaching level 50 in order to gain a prestige rank. This gives server admins fine-tuned control over levelling progression and reward, which very few alternatives provide.
To ensure that Lua can coexist with other bots, Lua’s prefix can be edited on a server by server basis.
The complete list of commands can be found on the official website.
