Ragefire Chasm
Ragefire Chasm is a level 10-16 instance located inside Orgrimmar. A good party of characters in this range will do well. There are a few tricky spots where multiple mobs will be pulled at one time. This will prove to be a challenging and rewarding experience for new folks just starting out.
*Important Bug Info*
Currently, as of patch 0.12, players releasing their corpses have their spirits appear in the Crossroads graveyard in The Barrens. This is a long run back to Orgrimmar and the instance.
