A modifier phase cannot affect the EM in anyway except to change its parameters.

Attributes of a Modifier Phase 

• When finding an EM of a modifier phase it will only identify the EM if only 1 EM exists or an EM is already running. It won’t identify a non-running EM if more than 1 exists because the modifier phase isn’t typically given enough information to choose but instead snaps to the previously started EM.
• The modifier phase will transition into the Run state as soon as it is able to apply its parameters.
• The phase state has nothing to do with the EM state and cannot affect the EM state.
• The modifier phase will continue running even if the EM is ended or returns to idle. However, the EM will remain acquired by the modifier phase.
• Stopping/Resetting the Modifier phase will only release the EM but will not affect its state in any way.
• Will not fault with EM or other phase failures except for unable to apply parameters.
