The epic combination of Amplify Magic and Quagmire.
Unknown to most RO players, this combination is one that would put the gods to a halt.
An Eir player named CrimsonStar made this discovery. As he casted it upon Valkyjra Randgris, the wind blew hard and the day became night.
Amplify Quagmire is said to go as far as keep someone in place with no movement. Legend speaks of a stronger version of this used only once by CrimsonStar, which made monsters and players actually move backwards.
