Grimrail Depot in the Adventure Guide

Dungeon - Warlords of Draenor

Grimrail Depot

3 encounters, 26 boss abilities and 151 drops, with the Adventure Guide’s own ability and strategy notes for each fight. Every drop links to its item page; tradeable drops carry a live Auction House price.

The Grimrail Depot is a vital hub in the Iron Horde war machine, allowing for the transport of troops and materiel produced in the Blackrock Foundry to the front lines of the war being waged across Draenor. The Depot's namesake is the Grimrail itself, a massive train that can bear entire battalions of troops and artillery. On this day, the Grimrail has been fitted with a massive railgun powerful enough to shatter the shield protecting Shattrath, and is about to depart....

Skylord Tovra

Before the rise of the Iron Horde, Tovra had never ventured beyond the frigid tundra of Frostfire, where she led groups of Thunderlord trackers to snare and capture the fiercest rylaks on Draenor. Her mastery of rylaks has made Tovra an invaluable asset, and she now commands the aerial forces of the Iron Horde.

Abilities & Strategy

Overview

Skylord Tovra engages players while her rylak bombards the platform, creating pools of Diffused Energy. The number of active pools increases as the fight progresses.

Rocketspark and Borka

Railmaster Pauli Rocketspark, chief foreman of the Grimrail Depot, has been enlisted by Garrosh Hellscream to build the technology required for the Iron Horde's infrastructure. Given the dim-witted assistant Borka to do the heavy lifting, Rocketspark set about building the Grimrail.

Abilities & Strategy

Overview

Borka the Brute assaults players with powerful physical attacks, as Railmaster Rocketspark uses his jet pack to move between locations on the platform, firing missiles when he lands. Rocketspark periodically unleashes a Missile Barrage, damaging all players. If Borka's Mad Dash strikes Rocketspark at that time, it will disrupt his Missile Barrage.
