Fluffy is perma out of the box for defenders (and corrs), so slot firstly for Tht_Debuff then some combination of heal/hold/immob depending on how you use him. An accuracy is nice too (later on, Acc/Mez HOs are good).
And take Darkest Night earlier! Like at lvl 6! 
CoX 50s: <ill/rad> <ice/ice> <fire/kin> <grav/sonic> <ice/storm> <earth/kin> <kin/elec> <cold/psy> <thugs/dark> <fire/dark> <dark/elec> <night widow> <EM/ninj> <mind/icy>
hehe ok swapped my early insertion of assualt for darkest night 
seems like a good combo will help all those db/wp toons out.
Not sure about leadership pool at all tbh with all the -res and -tohit i will have it seems like over kill.

I'd agree with no need for RecReds; initial slotting, Tht_debuff or Acc depending on playstyle.
I tended to solo with my D/D Corr, and use Fluffy as an alpha soaker for bosses etc... - drop him right next to the victim so the PBAoE debuff applies immediately, then drop Darkest Night, Tar Patch, and open up myself. In that case a Tht_debuff's a good starter, to help survive the alpha you're putting the poor chap up for.
If you use him more for routine ranged support against groups, you'll want his attacks to hit, so an Acc would be more useful.
twighlight grasp ftw you slot that right accuracy and heals maybe a to hit debuff(dont trust me on slotting i cant slot my way out of a paper bag) it works for me and btw how can you take it ONLY at level 4 
As the post suggests whats the best way of slotting this power..
I have just started a dark/sonic have a look any comments would be appreciated, im really trying hard to find a new toon to keep me intrested this is about my 5th attempt now
