Base module for all things magical. This module is required for supporting spells/casting. It is not necessary for being the receiving end of prots or such. Several modules are dependant on this module, most importantly those guild-specific modules that use magic.
Even in the case your guild does not use magic spells (nomad guilds), having this module loaded is not harmful, so you can keep it in your configuration at all times.
Basic code for blast hit and resistance reporting (some types, such as channeller guild blasts, are added by guild-specific modules).
Spell round reporting. Enables you to optionally spam your fellow players with information how many rounds are left until your spell goes off.
