Canon

Caster Creation

Casters are created in the same way as warlords; when a Side pops a warlord, there is a chance it will get a caster instead. The Side also does not get to choose the type of caster it receives. Some Erf culture appears to hold that the Titans decide when a Side will pop casters. There is no way to intentionally pop a caster.

Proposed Canon

Casters are units that can use scrolls and cast spells. While certain units can use spells or spell-like abilities (e.g. Archons), Casters are the only units in Erfworld that can learn and cast spells beyond their unit's specific ability or spell set. Casters are further defined as being Commanders and being able to form caster links. Casters are called by their class or discipline, so a caster who casts from Lookamancy is called a Lookamancer, and a caster who does general Hippiemancy would be called a Hippiemancer.

Using Magic

Every caster belongs to a magical discipline (e.g. thinkamancy or croakamancy) and can cast spells from that discipline. Some casters can only cast spells belonging to their discipline, while other casters can cast spells from multiple disciplines.^Erf-b1-p013 Multi-discipline casters are uncommon and there may be limits on what spells they can cast and how successful those spells are.

Casting spells uses a caster's juice^Erf-b1-p104 so there is a limit on the amount of magic a caster can perform during one turn ^Erf-b1-p090. Casters can extend this limit by creating and using scrolls. Scrolls increase the versitility of casters by allowing them to cast spells they don't know or spells that are part of a discipline they can't otherwise cast from.^Erf-b1-p126.

Commander

Like Warlords, Casters are commanders and can lead units in combat. ^Erf-b1-p084a However, they almost never do so since they are too rare and valuable to risk. Moreover, they do not have the Leadership ability and do not grant a Leadership bonus to units under their direct command. Some casters can grant a special bonus to particular units, presumably limited to those directly tied to their magical specialty. For example, Dirtamancers provide bonuses to golems under their command, and Croakamancers provide bonuses to uncroaked units.^Erf-b1-p084a

In some situations, casters can also grant abilities to units under their command. For example, a Croakamancer can grant the Dance-Fighting special ability to Uncroaked units under its command. ^Erf-b1-p127 The Caster would likely need to possess the dance-fighting ability on their own to be able to bestow it to other units.

Caster Links

Main Article: caster link

A Thinkamancer can join one or two other casters together into a caster link allowing those casters to cast powerful spells, multi-discipline spells, or create multi-discipline magical items or scrolls. The most powerful spells and items (apart from those created and used by Titans) are created by linked casters.

Magic Kingdom

Main Article: Magic Kingdom

The Magic Kingdom is an island that can only be entered by casters through portals in Erfworld cities. Communities of barbarian casters live here, and the island is divided into eight sections, one for each class of magic. Casters of the various disciplines co-mingle freely, including those who are members of different sides, who may enter and leave through Portal Park to socialize or deal with other casters for their Rulers.

As barbarians, Casters from the Magic Kingdom may be hired as mercenaries, for use by the hiring Side, as Faq did with Vanna.

Casters can receive orders from Warlords and Rulers while the caster is in the Magic Kingdom.

Croaked Casters

Once a caster is croaked they may be uncroaked. An uncroaked caster does not retain spellcasting abilities and functions as generic uncroaked infantry.^Erf-b1-p077a

It is currently unknown if casters can still cast after being decrypted. This, among other reasons, led Stanley to deny Wanda from attempting to croak Jack Snipe and decrypt him instead of healing him^{Erf-b2-p11-p6} (supposedly because the healing scrolls were getting harder to come by, probably due to resistance from Healomancers in the Magic Kingdom).

Thanks alot - your answer solved all my prbolmes after several days struggling
