Desslock of GameSpot reported that the game and The Scars of Velious "sold well early in the year, but sales evaporated during the course of the summer, especially after the release of Camelot".
The expansion introduced both Frost giants and Coldain dwarves to the EverQuest universe, and a group of dragons known as the Claws of Veeshan.
The expansion takes place on a moon of Norrath called Luclin and introduces the Vah Shir, a playable catlike race, and the Beastlord character class.
The Shadows of Luclin also incorporates a new game engine, new character models and gives players the ability to design graphic user interfaces.
Mounts were also introduced with this expansion – they allow players to regenerate their Health and Mana without generating as much aggro (hatred from monsters).
Fleeing Norrath because the atmosphere became toxic, the surviving Shissars were helped by the Combine Empire and were sent to Luclin and the underwater sanctuary introduced years later with "The Buried Sea".
Access to this plane can only be obtained through vanquishing the four elemental deities or avatars of such: Fennin Ro, The Rathe Council, Coirnav and Xegony.
To gain access to all of the zones of the expansion and successfully enter the Plane of Time, the players needed to complete 28 flag events of all sorts, involving the death of planar deities and deific creatures.
[8] The Planes of Power was a nominee for PC Gamer US's "2002 Best Expansion Pack" award, which ultimately went to Tom Clancy's Ghost Recon: Island Thunder and Desert Siege (tie).
To do this, Sony Online Entertainment introduced a storyline whereby the frogloks invaded the Troll city of Grobb and reclaimed and renamed it Gukta.
The zones were intended for mid-level adventurers between levels 36-60 and were generally received as very uninspired and added little to the lore of Norrath, but the guild management, extra bank slots, trading between characters utility and mapping tools are considered vital, and dyeing of armor is popular.
The expansion focused on high-level content, providing a number of zones meant to be used by large groups of players and many extremely powerful monsters to fight.
The wayfarers set up a base in the new lands of Taelosia, and provide the transportation system that allows players to teleport to the new continent quickly.
While the mechanic is now commonplace today, during its time the boss was widely considered "impossible" to beat until Cestus Dei on the Veeshan server conquered it on March 23, 2005.
For example, the instanced zones are also available in uninstanced versions, allowing people to explore them and gain experience by simply killing monsters without going into missions.
PC Gamer's Mark Crump gave the expansion a rating of 65% and said that a "twice-a year-pace of adding zones that are swiftly obsolete isn't helping the game out" and that SOE should have focused on current, lesser-used areas instead of creating tomorrow's forgotten ones.
This was done through the addition of a new town, home of the newly added Drakkin race, which provides various tasks for all levels of game play to gain experience, gear, and money.
The Serpent's Spine expansion also added the rest feature, allowing players who have been out of combat for a short period of time to regenerate mana and health at a drastically increased rate.
This is because some classes can expend their mana rapidly to cause large amounts of damage only to regenerate it with the new rest effect in the time it takes for their group to kill a single monster, thus increasing the total damage done in a group compared to the previous method of conserving mana to ensure a steady supply.
The letter by the current EverQuest producer, Clint Worley, revealed that the production cycle of the game was going to be altered to allow for one expansion release every year.
[20] Within the fictional storyline of the game, the evil gnomish necromancer, Meldrath the Malignant, takes his Fortress Mechanotus to the skies on a mission of destruction exposing a network of mineshafts and tunnels that lead across the Steamfont Mountains to the unexplored lands of Faydwer.
Within the fictional storyline of the game, Zebuxoruk, an insane fallen god, is the only person who can aid players in preventing the destruction of Norrath by stopping the evil forces of Discord and repairing the damage done to The Void.
The plot follows cataclysmic events in the region of West Karana which have torn an invisible seam to expose the Ethernere and bind countless realities, forcing players to defeat Lady Lendiniara to restore peace.
The plot revolves around Anashti Sul's newly discovered desire for power as her being is fractured into two aspects: life and decay.
Players must band together to stop her plot to plague Norrath with war to disrupt the balance of life in order to gain power for herself.
After decades of slumber, Imperator Tsaph Katta awakens and vows to reform the Combine Empire – the progenitors of much of the human race – by any means necessary.
[31][32] The game includes six new adventure zones based around the otherworldly Planes of Air and Fire, new raids, and a new "luck" statistic that influences the frequency of critical hits, the amount of gold in a player's split after defeating enemies in a group, and the success rate of crafting attempts.
It features six new zones along with new quests, raids, missions, and alternate advancement abilities for each class, as well as a new Dragon's Hoard offering additional storage space.
A powerful force known as the Akheva led by High Priestess Aten Ha Ra emerge in an attempt to re-establish their empire across the entirety of Luclin while the vampire lord Mayong Mistmoore also serves as a primary antagonist.
[50] Between 2001 and 2007, Sony Online Entertainment released retail bundles that included the original EverQuest and a collection of expansion packs.
