This is my current level 40 build, I am probably going to change it quite a bit after I've tried out a few different builds on test. It is also designed to be balanced between PvE and PvP, you may find it a bit light on control - for example for now I've skipped Vines and under-slotted Carrion Creepers, I'm almost certainly going to change Roots for Entangle but Roots is definitely handy for keeping groups bunched up for AoE attacks.

Skewer and Impale are your major attacks - as such, it is true that you don't do a whole lot of damage. However, once you get to 32 (Fly Trap), things improve dramatically since the pet, plus your 35 and 38 secondary powers, all do lots and lots of damage. Plus, of course, Carrion Creepers at 26 changes your entire combat strategy and will refresh your interest and enjoyment of the powerset.
Trust me on this 
It's a well paced set, that changes & improves at the all the right points.
Further to my earlier post, I have to say that Death Rose felt very squishy early on, and I considered her to be 'unsuitable' (not the same as impossible) to solo until she got to 32. However, as a part of a team, she has consistently been excellent, especially with fully-slotted Seeds of Confusion (which remains my primary 'attack').
So my advice would be to take pretty much all of your primary and secondaries (except for Spirit Tree, which is poor), but ensure that you heavily slot Strangler, Seeds of Confusion, Impale and Skewer. I personally would also recommend 2 or 3 hold duration in Strangler, along with 2 or 3 accuracy, and damage for any left over slots. Seeds should have a couple of confuse duration in it.
Hope this helps, but I certainly recommend continuing with the character, as Plant/Thorns is one of the most enjoyable powerset combos that I have come across in the game
Surely 3 accuracy is a vast overkill in Strangler, which has 20% accuracy bonus to begin with. I would also much rather slot recharge than damage. I've been happy with 1 acc, 2 hold and 3 recharge, although 3 holds and 2 recharge could also be the way to go. Personal preference, I like to be able to cycle it often.
You may very well be correct, as I'm at work and can't check. I think mine is actually 2 acc, 1 dam, 1 recharge, 2 hold duration...
I'm fairly new to COV and only have 2 characters at present. One Necromancer MM and one Plant/Thorn Dominator whci was my first bad guy.
I gotta say i think its a really great combination. I realise I am still only low level at lvl6 and have not exactly faced Huge chalenges with him yet but he is easily capable of handling anything I have yet met.
A sold set of powers I reckon.
Hi, i was wondering if i could get some information on rebuilding my character for when i get respec, as build i have now doesnt seem to have much attack power at all and is overall very weak.
its a Plant/Thorns based dominator and would like to know of a pretty decent build and enhancements to acompany.
any help with this will be greatly appreciated.
