Instance Guide: Ragefire Chasm
Ragefire Chasm is located in the Cleft of Shadow, in the Horde capital city of Orgrimmar. The Instance portal leads underground and is highly noticeable, as it is dug directly into the cliff face.
Ragefire Chasm is an extremely small instance and should take between 45 and 90 minutes, depending on party level and skill.
Ragefire Chasm is meant for a group with a rough average level of about 16, though 14 would be the lowest I would suggest and any characters over 18 would find the run rather dry on XP and loot.
The MOBs in the Ragefire Chasm range from 13 elite to 15 elite. The quest MOBs are up to 16 elite.
