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.

Casters are extremely rare, largely because they cannot be popped intentionally.
After a side pops its first caster, popping another caster becomes much more unlikely.
Many sides seem to have Thinkamancers (at least three among the combatants of the Battle for Gobwin Knob). They may be more commonly popped than members of other Disciplines. Conversely, even in the Magic Kingdom, Dirtamancers are apparently rare and in demand.
Some additional possibilities on how casters' numbers might be restricted:
- As a side has existed for more turns, the chance of popping a caster decreases.
- Each time a side pops a caster, the chances of popping another decreases.
- There is a limit on the number of casters in the world (could be based on each type)
- The odds of a caster popping decreases as the number of casters in the world increases
- There is a hard limit on the number of casters in the world
- It may be that sides are limited to a maximum number of casters. For example, three or fewer, with it being rare but possible to pop up to three casters. Capture, however, would be more beneficial since it allows for more than the minimum number and it means the casters may have already leveled.
Casters, Sides, and the Magic Kingdom
The Magic Kingdom is a special location that only casters can enter. Casters from active sides can enter and exit the Magic Kingdom via portals. However, some casters in the Magic Kingdom do not belong to sides on Erfworld. The number of casters in the Magic Kingdom may, at any given time, outnumber those elsewhere on Erfworld.
Leveling for casters may work differently then for other units. If casters need to kill enemy units to gain experience then leveling could be very difficult due to the fact that casters tend to be kept in capital cities. Some types, such as florists, might not even possess any magical means to croak another unit. Note that in Book Two, Text Update 45, Sizemore says that he has gained three levels recently, two from croaking units ("from traps and combat") and one from other activities ("from all of the city rebuilding"). So it seems canon that not all caster leveling comes from croaking units.
Caster levels are often refered to as their class, often before the type of caster. This class may also determine what ability a caster has at casting spells outside their discipline. A master-class caster may be able to cast spells that are not their forte with greater ease. An example is Wanda who is a Master-Class Croakamancer but claims to be able to cast other spells with ease (though she has little interest in doing so), whereas the two other casters most commonly seen (Maggie and Sizemore) either cannot or do not cast outside of their discipline. It is known Maggie is only an Adept-Class, but Sizemore's class is unknown. Given his power compared to Wanda's, as well as his expectation that he could reach master class prowess soon (Book Two, Text Update 45), it seems likely that he is only be an Adept at the middle of Book Two. If so, this would offer an explanation as to his self-professed lack of talent in other disciplines.
It is possible that casters gain experience by using magic or by simply participating in a battle in any way.
