Does Heimerdinger's abilities apply on hit effects like Rylai's Crystal Scepter's slow or Morellonomicon's grievous wounds effect? Specifically, do his turrets apply these effects each time the turret attacks or is there a grace period before the effect can be applied again by the turret? Also, do the turrets apply basic attack on hit effects like The Black Cleaver, Frozen Mallet, or Wit's End?
Zarxis2 votesRylai's and Morellonomicon apply spell effects, not on-hit effects. If I remember correctly, the turret laser blasts do apply spell effects, but the regular turret attacks don't apply anything.
Tylo Snoyer1 votesSo only the laser blast from the turrets apply the spell effect, but the other attacks from the turret just do flat magic damage?

Yes. The laser applies things like Liandry's/Rylai's/Morello's (spell effects), but not Frozen Mallet/Black Cleaver/Wit's End (on-hit effects). The turret basic attacks don't apply anything at all.
