I think you'll have to find the [statedef -3] of a character first Then add
[State -3, aura]
type = PalFX
triggerall = alive || !matchover ;<--- Means that the effect will take place if the player is still alive and the match is not over yet
trigger1 = 1; <--- Means the state is always executed
time = -1
add = 0, 0, 0
mul = ceil(256+abs(180*sin(gametime*.015))),ceil(256+abs(180*sin(gametime*.015))),ceil(256+abs(180*sin(gametime*.015))); <--- Don't pay attention & just add it, got the code from a friend
color = 256
invertall = 0
ignorehitpause = 1
supermovetime = -1
pausemovetime = -1
persistent = 1
