Welcome to Gaia! ::

I'm not there yet, probably won't be for awhile, but I'm planning ahead...

It'd be around now that I'd be seriously considering waving goodbye to my Voidwalker and dumping my talents to be putting it all into Demonology for the Felguard (It's the soul [sole?] reason for my wanting to be a Warlock so you can't talk me out of that) if I haven't done so already..

I'd have picked up the quest to go into Sunken Temple (and talked guildies into running me through because I'm cheap like that) which is an instance I love doing.. I think it's the dragons.

And I'd have come to the end where I'd have to choose of three rewards;
Soul Harvester: http://www.wowwiki.com/Soul_Harvester
Abyss Shard: http://www.wowwiki.com/Abyss_Shard
Robes of Servitude: http://www.wowwiki.com/Robes_of_Servitude

I'm not sure if the rewards are going to be altered in any coming patch but, assuming they're not, which one should I be aiming for?

They're all really nice. The shard is great because you can keep it ant use it any time, though if you're not going to use your voidwalker that often it's not as good...but it does keep.

The scythe is the only scythe looking thing you will ever get as a caster class. There's some scythe polearms in outland but nothing you can use. I took the scythe, and I still have it.

The robe is also great. It has an awesome design, and there's not another robe like it (even in a different color).

i suggest the Robes of Servitude it helps increase all your spell damage, but if the soul harvester is better a weapon than what you have get it, i advise aggainst the trinket if your going demonic because whats the point in being able to automaticley summon a voidwalker when you have a felguard.

Shard FTW.
The others will get replaced after a few more levels...

i never got an ST run however i whould say the staff just cause its awsome looking

even thoe if you want useablilty and long term think the shard free SS every 10 mins cause you can do the summon make you pet stay wlak away till it despawns

i have a better robe and staff from the 1st two quest i did in outlands that gave items out
