Propagation (also known as prop or propping) refers to Formation Abilities with an effect similar to Mycall's Propagation, which has the following effect: "Causes other Crusaders' Formation abilities that target Mycall the Mushroom to apply to Crusaders next to Mycall, at x% effectiveness (no effect on Crusaders who are already targeted)".
Some Formation Abilities cannot be propagated by any means. In these cases, the ability is marked with "(Can't be Propagated)".
The following Formation Abilities qualify as Propagation, as well as their Mimic and Copycat versions:
- Mycall's Propagation
- Tiernan's Druidic Patterns
- Langley's Flip the Switch
- Audre's Spreading the Love
- Adina's Hero League*
* Technically, Hero League is a propagation ability (i.e. it cannot propagate Matt's Cryo Freeze). However, due to its drastically different uses, mechanics, and restrictions, Hero League is not considered propagation by players.
Karen's Center of the Universe is not technically a propagation ability. However, if Mindy (or Torakichi) mimes both Karen and a propagator, it can serve as an extra form of propagation. Center of the Universe (Mimic) will multiply Formation Abilities that don't target Mindy then apply them to Mindy; since they now apply to Mindy, they can be propagated as expected. This helps to further multiply any affected Formation Abilities, as well as further change your formation's requirements.
