Felweaver is an online gaming community built around two classic World of Warcraft expansions: Wrath of the Lich King and Cataclysm. Its website provides information for players, including game guides, server status, databases, world descriptions, talent calculators, rankings, an armory, arena statistics, guild listings, and community links.

The project promotes challenging group content and progression through features such as Mythic dungeons with timed keys, scaling difficulty, and combat modifiers, alongside high-difficulty dungeons and raids. Players can also summon alternate characters from their accounts, controlled by server-managed AI, to join activities in the open world, battlegrounds, and dungeons. Weekly rewards are organized through a Great Vault covering raids, Mythic keys, and PvP, while a battle pass offers additional rewards for completing activities.

Felweaver’s Cataclysm world includes new races, progression to level 85, raids from Blackwing Descent to Dragon Soul, flight across Kalimdor and the Eastern Kingdoms, archaeology, and new professions. The site describes its progression as balanced and without pay-to-win in Cataclysm content, with quality-of-life changes intended to preserve the expansion’s character. Players can register on the website, download the Felweaver launcher, and use their account credentials to play.
