Scepter/Dagger and Staff are the way to go.
Personally I recommend full Rabid gear. The precision will help you with bleeds immensely, in addition to dhuumfire procs. I sit around 50% crit with that and though I’ve considered swapping some Dire gear in for the added survivability, I’m pretty comfortable with what I’m using now. Personal preference and all…
We have a lot of utilities and there’s plenty of good arguments for using X over Y or Z, but as a small group roamer this is what I’ve settled on.
Consume Conditions – Don’t think there’s much to argue with here… just use it.
Signet of the Locust – I use this to give me some run speed but the first thing I do as soon as I think we’re going to be into combat is switch it to…
Signet of Spite – The passive is useless but the active is awesome. I usually use it in one of two ways. (1) Use it to draw out the opponents condition cleanse. SOS doesn’t do much damage itself, but a lot of time people panic when they see the mass of conditions piled up on their bar and use their cleanses to remove them, allowing you to do your damage with ease. (2) The other way I use it is after a corrupt boon, then follow with Epidemic. More on this later.
Corrupt Boon – Awesome skill. I can’t imagine playing any necro spec without this on my bar. The big thing to look for is Stability. As a Terrormancer, Stability is your nemesis. Make sure to wait until the enemy has a number of boons up for maximum effect.
Epidemic – This skill can turn the entire fight if you’re fighting more than 1 person. It has a 1200 range so it’s pretty well guaranteed to spread the pain to the all of your targets’ allies. (Up to 5 of course). If you’re roaming with another condition class make sure you’re both targeting the same person. Use Corrupt boon if they have a number of boons, then SOS to add some more condi’s, then Epidemic to spread the pain. A well timed use of this skill can really turn a fight.
Flesh Golem – While I like Plague for large combat/zerging, in my opinion Flesh Golem can’t be beat for small group roaming. The power of this spec lies in the CC you have available through fear. Load them up and then fear them so they’re forced to watch as your condi’s do their damage. The Flesh Golems’ knockdown ability in effect gives you an additional fear.
Scepter/Dagger is where you’ll do most of your damage while Staff is a great utility weapon.
The only other thing I’d add is to make sure you save your condi transfers for when you actually have condi’s to give back. It’s pretty easy to remember because regardless of what weapon set you have equipped, the transfer is on the #4 skill.
Good luck!
even in wvw xp popping like crazy.
