- Can rig rules in a unit's favor. It appears that the Carnymancer makes a 'deal' to do this, though the exact nature of this bargain is unclear. It would however seem that Carnymancy spells, rather than modifying unit specials or other stats, might affect the actual rules upon which Erfworld operates.
What is clear is that the effects of Carnymancy must somehow be distinct from the effects of Luckamancy, as they each occupy a separate magical axis, and Luckamancy so far seems less permanent than Carnymancy (one 'borrows' to produce its effects, the other makes a 'deal'; one operates within the 'rules', the other changes them).
As indicated by the Predictamancer Marie Lavraie, like a carnival carny it may be that carnymancers take non-carnies as stooges or suckers to be played. It is possible that carnymancers lie to these suckers as required to manipulate or alter Fate. After all, who but a master cheat would claim to be able to cheat Fate itself?
- Similarly, Carnymancers may also be related to modern day con artists for their tendency to trick 'marks' into participating in their scams.
- Alternatively, Carnymancers may adhere to a 'trickster' archetype, where their actions are not explicitly meant to harm or inconvenience an individual, but may also help or instruct.
- Both above considerations would fit in with the 'rule-altering' nature of Carnymancy, as it could serve to alter the 'rules' (or morals) which a unit 'plays' by. To keep this distinct from Hippiemancy (which alters a target's perception and might 'suggest' a course of action a unit would already be open to under a given circumstance), Carnymancy might instead influence that unit, to change what they consider to be an acceptable course of action in a given situation. As it is a form of Stagemancy, along this line of thinking it would also not be unreasonable for Carnymancy to be used to 'teach' a unit a new 'trick' (e.g., 'teach' them a new Special such as Archery).
- Possibly the Fate magic behind the Arkenhammer.
- May reduce enemy abilities, similar to how carnival games are 'fixed' to be disproportionately difficult.
- May have minor abilities of other schools, which would explain why the Arkenhammer has so many different and wild abilities.
- May involve taming of wild units, which would correspond to the Arkenhammer, like in a circus carnival.
- May involve mesmerizing the enemy with flashy production values, if Carnymancy was the extra element in the Vanna "Wheel of Fortune" linked Turnamancy spell. Since carnivals involve fooling the "townies", are there links to Foolamancy?
- Being in the Fate axis, could involve the alteration of cause and effect, totally redefining the show.
- As it is said to alter rules, Carnymancy might be capable of such feats as modifying archery attacks so that they could hit targets across hexes off-turn instead of hanging in midair, or preventing a specific unit from being injured or incapacitated by falls, and so on.
- It may provide a means to dispel or cancel other magic, as Jojo claims that he has a spell that can send Parson (who was summoned by magic) back to Stupidworld.
- Alternately, its effects might operate further outside the rules, as Sylvia suspects that, when they both served Unaroyal, Jojo might have made a deal that would prevent her from ever being permanently croaked.
