mobs leave afterimage when killed by skill altering mob status

[Bia10]

dmg is barely apparent just disappearing while mob after images appear frozen they will disappear ~0.5s later

[Bia10]

some further notes:
not all mobs are affected the same

the process:
mob takes hit
mob dies
mob sprite get de-spawned
mob sprite reappears frozen, the duration spent reappeared varies from mob to mob, bigger last shorter
mob sprite de-spawn finally
