Well, I feel like you are sacrificing too much for some extra chill.
First of all, the Chill on Blind trait has a 5 second ICD. Well of Darkness and Nightfall will only proc it once, and the snowball sigils will make them even less likely to proc it.

Spectral Grasp is pretty bad, and Suffer is also pretty bad. Even with Chill in mind, you should always take Plague Signet/Corrupt Boon/Spectral Walk/Spectral Armor over Spectral Grasp and Suffer. Well of Darkness isn’t terrible, but it isn’t normally on par with the four utilities I listed.

I strongly advise you take Soul Reaping for Dhuumfire. Before I say more, what is this build for?
