primary target.

AoE (Area of Effect)
-(noun) AoE refers to the powers and spells that affect a given area. Usually there is a designated
target and a certain radius of affect. Some AoE effects are instant and some are timed. For timed AoE
effects, an anchor is needed. A common MMORPG AoE powers is fireball where everyone
surrounding the target of the fireball will also get damage.

Anchor
-(noun) The target chosen for AoE timed effect. The AoE effect can be either buffing or debuffing.
Often debuffing powers lasting a period of time are cast on a particular enemy affecting all enemies
around him. That target or the anchor is often kept alive to keep the effect on going. Whereas,
buffing effects are placed on the group’s anchor so that all members surrounding the anchor will
receive the benefits of the buff.

over 20 second.

DPS

are those who can do a lot of damage per second.

Farm
-(Verb) To repeatedly gathering resources and killing enemies on a particular area. Once an area is
cleared, new enemies re-spawn and are killed off again to obtain rare loot, money, items, experience

draw the attention of the remaining mob.

Tanking usually requires high defense, a lot of health, and primarily melee abilities.

Train
-(noun/verb) The event or the act of a player who intentionally or unintentionally aggro a group of
enemy and is being chased by a line of that mob much like a train of cars. Generally, this is done in

to expulsion in some MMORPGs.

If you can think of more please post them!

okay i have to say this. newbie and newb are NOT derogatory terms. they are simply used to describe a new player. noob/noobie/nub are derogatory. please don't get them confused.
Noob vs newb
Wiki

and many other sources.

I think this is generally a good type of guide to post, but it probably needs to be re-written to the specifics of this game. Some of the definitions in this list do not apply to Dungeon Runners or are derogatory.

1) Laurana's dead-on about newb Vs. n00b. They are completely different

2) Anchors do not apply to this game, for now. Anchors are very common in some other games like CoH, however.

3) Trains do not exist in this game.

4) I take exception to the negative comments regarding PuGs, especially since this game's group play is entirely based on PuGs (for now). Also, everybody starts with a PuG. That's how one makes friends in online games.

5) Thus far, I've never seen anybody abbreviate any of the dungeons except HDoL. The only one I've ever abbrevieated (other than HDoL) is Mutantous Malaise as MM. Personally, I like that players actually spell out the Dungeon names.

I've seen Vergrim's as VV, but yeah, I've yet to see any other abbreviations for dungeons beyond that and HDoL. Let's not force this game into unintelligible slang before it degrades there naturally, shall we?

heh i abbreviate everything. scientific habits and all that. if it's aname with more than one word it gets abbreviated

Well done. Since I agree with the other comments posted thus far.. I've nothing else to add.

Yeah, what StrayLOA said!

There are a couple of minor typos and grammar errors, too. Under "DoT," the last word should have an "s" added. Under "Farm," the first word, "To," should be deleted.

I have always used "PBAoE" rather than "PBAE."

Yes they do. Train doesnt always have to mean someone pulling a group of mobs to dump on someone else, or someone running from the mobs. It could be someone pulling the mobs to get them close so they can spam an AoE to kill them.

I always called that 'herding'.
<shrug>
But I have always used 'train' to mean 'lvl up skills'.
<shrug again>

And I'm in the group that says 'newb' and 'noob' are VERY different.

^.^

I am also in the newb vers noob group.
Newb is acceptable and used by people to simply state they are new to a game.
Noob is used to describe someone who is obnoxious, full of themselves and generally not a nice person.
