In keeping with Patch 1.12, groups of up to 10 players may enter Lower Blackrock Spire together. LBRS can be accessed without a key, unlike the upper part, Upper Blackrock Spire (or UBRS), which requires Seal of Ascension to access. It was operated by Dark Iron Dwarves for centuries, created to serve as a symbol of their sinister ideologies until Nefarian, son of Deathwing, took control of the Upper Spire and declared war on the dwarves, as well as their leader, Ragnaros. Located within Blackrock Mountain, Blackrock Spire was designed by master dwarf-mason, Franclorn Forgewright. Lower Blackrock Spire, often shortened to LBRS is the lower half of the Blackrock Spire dungeon in Classic WoW. Season of Mastery Overview Updates to Molten Core
Season of Mastery will feature faster leveling, new raid mechanics, the removal of world buffs in raids, and many other changes. When the Season ends, characters will have the option to transfer to permanent Classic Era realms before the Season servers are shut down. Seasons will have six content phases, lasting roughly 2 months for each phase, for a total of a 12 month cadence. World of Warcraft Classic is getting its first "Season" with Season of Mastery. This is a change from Classic WoW, where several dungeons were released in later phases, and many drops were added or changed bosses in Phase 5. In Season of Mastery, all dungeons and dungeon gear are available from Phase 1 (launch) from the bosses indicated in this guide.
