Patch notes Oct 1 (level 30) – Part 1/2: General
New with the beta's level 30 update:
- Level cap is now level 30
- New dungeon Excavation Site: Wetlands (26–31)
- Newly accessible: Razorfen Downs (25+) and Uldaman (30+), plus all previous dungeons
- Barbers now also in Darnassus and Thunder Bluff, all staffed; city guards show you the way
⚔️ PvP
- Honor costs for PvP gear and upgrade tokens raised by about 50%
- Honor cap raised from 15,000 to 25,000
📜 Quests & leveling
- Dungeon quests give 50% less bonus XP (Blizzard doesn't want leveling to be too fast)
- Faster respawn of enemies and quest objects in Hillsbrad Foothills, Ashenvale, Wetlands, Duskwood and Thousand Needles
- Escort quests can be started again even with 25+ quests in your log
- Mulgore: new quest "Kyle's Gone Missing!"; Orgrimmar: more "Smooth Boulder" for "Rocks to Rests"
🏕️ Camping & items
- Campfires no longer damage players below level 5 and deal less damage to players below 90% health
- Clearer display of the "Boosted Rest" buff
- BoE items with an uncollected appearance become soulbound (instead of account-bound) when sold to a vendor
🔨 Professions
- More Blacksmithing and Leatherworking recipes available as dungeon drops
- Skinning: creatures can once again be skinned only once
- Fewer poor copper veins in starting zones
🖥️ Interface
- Note in the character window: low spell ranks benefit much less from spell damage and trigger talents less often
- The Auction House shows item suffixes ("of the Bear" etc.) correctly again
⚠️ What this means for you: Leveling through dungeon quests is less rewarding, but quest zones for levels 20–30 are more relaxed. PvP gear gets much more expensive, so start collecting honor early.
