Invincible's Reins

Arthas Menethil’s famous steed served the prince both in life and after death. To ride it is truly a great feat.

These reins are a reward for defeating the Lich King, the final boss of the Icecrown Citadel raid.

The raid is located in the Icecrown zone.

You can reach this zone through your faction’s portal room. The portal will take you to Dalaran (Northrend). Then, use a flying mount or the Flight Master’s services to travel to the Icecrown zone. The raid entrance is at the very bottom of the citadel.

The drop rate for this rare mount is ~0.8 %.
