Illusion / poison troller build - for red side

I have a concept I'd like to try out -- an evil illusionist / user of toxins -- as a returning premium player with access to only SOs.

I'm wondering about slotting for Spectral Terror, in particular; One synergy for this build is that to hit debuffs can stack to noticeable levels, and so having Spectral Terror hit reliably would be good. But, a couple of extra slots in the heal would be nice (an extra heal and an end red would probably go in there).

Any build feedback provided would be appreciated, and thank you in advance.
