Plot synopsis
The setting of the game is in the same universe as AdventureQuest, DragonFable, and MechQuest. The universe of AdventureQuest Worlds came into being when the Dragon of Time was defeated by Galanoth leading all the stray storylines of the previous games to come together into one.
The plot centers on the player hunting down the 13 Lords of Chaos, a group controlled by the antagonist Drakath. The player may also choose to side with two other factions known as Good (led by King Alteon) or Evil (led by Gravelyn) who have teamed up to fight Drakath and his 13 Lords of Chaos, each of which can summon a deadly Chaos Beast.
Gameplay
Instead of turn-by-turn basis battles (as in previous Artix Entertainment games), it uses real time battling with simultaneous players/monsters. Like many RPGs, players advance by gaining experience points from killing enemies and completing quests, and gather currency and equipment. Equipment is only valuable cosmetically with only slight differences being the range of damage that weapons have. All equippable items, except armor and pets, can be used with “enhancements” to give stat bonuses which include Strength, Intellect, Dexterity, Wisdom, Endurace, and Luck.
AdventureQuest Worlds includes many classes like warrior, rogue, mage, healer and special advanced classes like dragonslayer, ninja, pirate, shaman, warlord, enforcer that players can unlock and switch between, typically by completing a quest chain or series and then buying them. Players can own as many classes as they want, but can only equip one at a time. Each class currently has six skills including two passive skills. As a player uses a class more, he/she gets experience in that particular class. Each class has 10 ranks that can be reached by gaining class experience. Each rank (up to rank 5) unlocks a new skill (or at rank 4, 2 passive skills) for the player to use. Some classes also have passive skills unlocked at rank 10.
