My Search-Fu is weak... Creepers slotting?

That's a pretty wide random spread of options there. I didn't find anything definitive either, so I was hoping someone would be able to tell me how much accuracy it needed to be effective and if it actually did enough damage on its own to warant slotting for damage.

It does need about 2 SO's worth of ACC if you're gonna be playing on big teams or cranking up the difficulty when solo. It also really need 3ish slots of Recharge to be up often enough. The damage is already quite good (especially against large numbers of targets) so you don't really need much there so going with a Frankenslotting approach seems to be the best answer.

Here's my slotting for it:
Enfeebled Operation: Acc/Rech, Trap of the Hunter: Acc/Rech and the proc, Kinetic Crash: Rech/End, Positron's Blast proc, Explosive Strike proc.

It's a beautiful sight, especially when those three procs really start going off. >Grins<

Thanks for the response from personal experience, that's exactly what I'm looking for.

So, until non-generic IO's, figure a standard slotting of 2 ACC's and 2-3 Rech?

2 SO's worth of ACC and 2-3 SO's worth of Recharge, yeah. Either through SO's and generic IO's or actually Frankenslotting with Acc/Recharge IO pieces. Either way works quite well.

On my Plant/Psi Dom, I have it slotted with 3 procs and 3 "other" pieces to bring it to where I want it to be. You also have to be careful when frankenslotting this power because of the way it passes down IOs to the sub powers of the Carrion Creeper Patch (the powers of the pet that the Carrion Creepers power spawns). Here's a link to the pet the power spawns: Carrion Creeper Patch

So for example, if I were to slot an Explosive Strike proc into the power, it would only fire off on one of the attacks of the vines. If I slotted a Trap of the Hunter Proc, it would only fire off when the immobilize effect of the patch triggerd. However, the Impeded Swiftness proc would fire off in all of the vine attacks plus the bramble patch (auto slow patch around the pet). Targeted AoE Procs would fire off in the immobilize and in all the vine attacks. That is why I chose the Positron's Blast proc, the Javelin Volley Proc, and the Impeded Swiftness Proc. I then put three pieces of the Ragnarok set in it to bring it to around 79% damage, 59% acc, and 59% rech.

The same goes for non-procs. If you slotted a Acc/Rech from Trap of the Hunter set, it would not help the vines' Accuracy at all, but it would help the immobilize portion of the power. It's best to stick with a common accepted IO set, which happens to be Targeted AoE sets (Unless you don't care about the vines' accuracy or damage that is).

Since my dom is perma, I can get away with 59% recharge and still have it up before it expires. That with sleet means the vines never miss and the procs are just beautiful. I can sit around a corner and throw out Creepers, Sleet, and Ice storm and kill a +2 x8 mob of guys without using any of my other powers.

For a non-expensive route, I would go with a combination of Targeted AoE Acc/Dam, Dam/Rech, and Acc/Dam/Rech pieces, and maybe just two procs (Posi Blast and Impeded Swiftness). Try and bring the recharge up first, then the accuracy, and last the damage. You might even be able to just go 2 Rech IOs and 2 Nucleolus HOs at lvl 50 and call it a day.

So, you realize that your Ragnarok only helps some of the powers right?

I have mine slotted with two neucleus, impeded swiftness proc, posi proc, and two recharge. I experiemented with several other variations and so far this has worked best.

You really, REALLY need accuracy on this baby and you will notice the difference with it slotted for damage. Enemies stay inside it, and it draws aggro so enemies outside it run in. Damage on this thing is amazing.

It should be helping all but the bramble patch, as the damage IOs should pass down to the vines and the immobilize patch.
