Damaging Sleep power, with Damage Proc

I have Siren's Song, from the Sonic Blast set. I want to slot it with Positron's Blast's "Dmg proc", but I am wondering; would the proc awaken the enemy from their sleep, even though it's from the sleep power?

Short version: Yes

I see, so i take it the long version has something to do about, the sleep will activate, followed by the proc damage, which if activated would awaken the enemy? Some sort of order thing like that?

I have and use Siren's Song, complete with posi and the PvP damage proc, and I have yet to witness either disturbing the Sleep effect.

Hmmm... conflicting statements. Well, if you have seen the damage trigger (i suppose we should consider the fire damage from judgement also), and they stay asleep, then I'll take that as a no disturbance to their sleep. I appreciate any final answers for this as I'm about to respec my toon and this definitely plays an effect.

The fire damage from Reactive Interface does disturb the sleep, as it's a damage over time. Damage and damage procs seem to occur together, and then then Sleep applies.

Thanks for that info. I'll have to remember to not use reactive if I wish to use a sleep power... perhaps diamagnetic will be the way to go, or just go with the reactive that has no fire damage. Thanks for the help!

If you look under the 'Effects' tab for Siren's Song (or under the Window tab >> Data View) you'll note xx.x second Sleep (mag 3) to Target (after 0.25 seconds, to Critters). That delay of 0.25 seconds is why the sleep works as intended, damage then the sleep.
