ORB EFFECTS THAT DO IN FACT STACK!!!!!!!

S&Y and Mejolner / satanic / skadi
only if a hero / creep is sanged will the lightning / lifesteal / frost not go off.

and for example... if you get S&Y, mejolner and skadi with (lets say) Mirana. Put S&Y top, below it Skadi then majolner....
this way she will constantly att frost attacks (skadi) every so often (usualy first hit) she will sange (that sanged hit will not be a frost attack but will still slow due to sange), her lightning from her majolner will go off on its usual percentage ( that hit will also not be a frost att or a sange)

its awesome!
