A spider-like pod driven by steam and piloted by a Gnome. No actual mobs in the game have the name “Spider Tank” and they are just dubbed this by players. Spider Tanks which can be fought are found in Gnomeregan, though others which just serve as scenery can be found elsewhere, such as in Dun Morogh.

Named Spider Tank Mobs:

Electrocutioner 6000 – A boss in Gnomeregan, and a big Spider Tank.
Mechano-Tank – Standard mob of this type.
Mechano-Flamewalker – Flame-throwing mob of this type.
Mechano-Frostwalker – Frost-spraying mob of this type.
