Role-Playing Games (RPG's) are fun and enthralling. The immersing affect they have on the people participating is a product of the high level of interaction involved in playing an RPG. As the name suggests, role-playing is central to the experience. To role-play, all one has to do is take on a particular character's role and act it out. In a basic sense, it's like putting on a play without a script. There is a setting and a loose plot. Environmental elements or props are provided, but it's up to the players to create their own stories. Role-playing typically requires a bit of imagination and creativity too. The only thing that separates an RPG from the act of role-playing is that an RPG occurs within the confines of a game structure with general rules put in place to produce a specific and expected experience. RPG's are a package comprised of role-playing and other elements that enhance the experience. Unlike a general role-play setting for uncompetitive acting, the game of role-playing is an experience that usually has winners, losers, rankings, and a motive for playing and competing.
Aggro; When a single monster or group of monsters is attracted to you because you stumbled into their field of view. Drawing too much agro can mean a very quick death, so pull one at a time. You can determine which enemies you’ll aggro in GW by the small transparent circle surrounding the player’s position on the mini-map – if any enemy “trips” over this they’ll be all over you.
AI; Artificial Intelligence. Often refers to the AI of heros and hench along with the AI of enemy npc's. AI level will differ in NM and HM and between low level and high level areas.
AoE; Area of Effect refers to any skill or attack that has an effect (usually a radius of “x” distance from the initial attack/casting point) that will hit more than one enemy. AoEs can take many forms, from offensive spells and attacks to heals, buffs, and everything between.
Battery; This generally refers to a blood necro using skills such as blood is power or blood ritual to keep a constant supply of energy to monks and ele's. Even at low blood attribute settings BR is very helpful to most teams.
Build; This refers to the type of character you play and the skill set that goes with that character.
Buff; Any enchantment that imbues the player or players with a beneficial boost, whether it applies to an attribute, skill, etc. Think of it as temporarily turbo-charging your character beyond his or her normal abilities.
Combos; Combos or combo-ing refers to using two (or more) complementary skills in rapid succession to inflict more damage or increase the efficiency of a buff or heal.
DD; Direct Damage. This applies to any spell that delivers its full payload of damage in one shot, as opposed to spread out over a span of time (DoT).
De-buff; The opposite of a buff, and is any skill, that removes the beneficial effects of a previously applied buff.
Degen; Degeneration. Refers to when either health or energy is stolen, either in a single attack or DoT skills. Zealous or Vampiric weapons also cause degen when equipped. Some Elite areas may have degen areas too.
DoT; Damage Over Time refers to any skill attack, etc with a lingering effect that continues to cause damage after he ability is initiated.
DPS; Damage Per Second is an equation that takes the players character’s variables and generates the amount of “x” damage generated over a “y” span of time. The higher this number is, the better, though, in most cases, this isn’t a number that’s easy to arrive at.
FDS/IDS - Fiery/Icy Dragon Sword
Grinding; The practice of staying in the same general area killing the same monsters (or doing the same task) over and over to earn EXP rather than participating in quests. It can also reefer to exclusively killing monsters to level.
HM; Hard Mode, gained once one of your characters has completed a campaign. You can then select to do an area/mission in HM in that campaign with any of your characters. The enemy will be of a higher level and AI but will provide better drops.
Interrupt; Any skill, attack, etc that disrupts a foe’s ability to launch one of his own. This is an advanced skill as it requires knowledge of how long an enemies skill will take to execute.
Kite; Kite or kiting something is a technique whereby you attack a foe from a distance and then, using an ability to slow (or in a Ranger’s case a pet to harass), you attack the foe from the intended target – like flying a kite, which is where the term derives its name. It can also be done, if the player is fast enough, without any sort of hindrance to a foe.
Knockdown; Anything that causes an enemy to be knocked down on the ground, disrupting their offensive moves ad leaving them open for further abuse.
LB; Refers to Lightbringer Points in Nightfall, ie LB farming
Loot; The spoils that are collected after a fight, and the process of collecting them.
LoS; Line of Sight refers to any skill that require the target to be in view. This means that if the enemy/ally is behind something or over a hill, the attempt will fail.
LvL; This is shorthand for a character’s level, the higher the better!!
MM; Refers to a minion master, usually a necro, who exploits corpses to create a wall of minions.
Mob; The term for any enemy or group of enemies who are tied together via the game’s systems. A mob could be a White Mantle Knight or a full squad of them and a boss. The term is short for “mobile”.
Nerf; To reduce the effectiveness of a certain item, profession, skill, etc
Newb/n00b; Newb or newbie refers to someone who is new to the game (such as a low level character). People using the term in general chat are usually looked down upon.
NM: Normal Mode, the standard mode for areas, as opposed to HM.
Nuker; More commonly referred to a fire elementalist
Pulling; This is a very important concept in GW. As you’ll only want to deal with one mob at a time, pulling is a handy skill the you need to hone to a razor’s edge. It refers to snagging one enemy and/or mob at a time when many are lurking.
PVE: Player Versus Environment. (Includes NPC (Non-Player Character) monsters, traps, riddles, puzzles, etc.)
PVP: Player Versus Player.
Res; Res or Rez is short for Resurrect, which brings someone back to life after they have been felled by an enemy.
Solo; Solo or soloing is the practice of playing an RPG alone. While this is fun, RPG’s are geared towards team work, and in some cases, soloing is impossible.
Spam; Spam or spamming is the practice of using spells over and over again, specifically spells with low Energy cost, low casting time, and low recharge time. Also repeatedly posting the same message over and over in chat in a short period of time (considered very irritating).
Spike/Spiker; To concentrate attacks on a single foe, either by individuals (a spiker) or the team as a whole. ie a PvP Mesmer may have the role of spiking the opponent monk or ele with constant energy degen attacks.
Stacking; Denotes how certain skills can be cast on top of one another to increase damage or the potency of attack or buffs.
Tank; Any player character (or NPC Henchmen) who can serve as a primary melee fighter/damage sponge on the team.
Touch; Usually refers to a ranger or necro using blood health stealing touch skills to kill an opponent.
XP or Exp; Experience points.
Zerg; Zerg or zerg’ing refers to over-whelming a foe with a death of a thousand cuts”. In GW GW Terminology
