agree with pizymisa. we don't know the stats for sure but it's not very reliable now -- much like other supplementary skills like confusion, paralysis and hypnosis. but when it does work it helps a lot. it is still a good skill to use when capturing epics in caves.
I have found it rather effective on Invalidating Champs with Absorption and Pewgways with Soak. You seduce the opponent, and continue healing to ensure that the effect lingers for as long as possible.
I fought Lupa with seduction for several times in PVP 2v2, in my exerience its like 60~70% still. im using all S rank Level 50. Or maybe im just out of luck but it made me lost the fight really annoying.
