Central base "building"; has the usual 3 levels. Can move! Must "entangle" a gold mine to enable mining.

Produces Heroes.
Ancient of War[edit | edit source]
Produces basic combat units. Can move!
Hunter's Hall[edit | edit source]
For upgrades.
Ancient Protector[edit | edit source]

Defensive "building". Needs to be used with special care to be effective, primarily due to its minimum range. Can move! This allows you to move your Tower complex to defend your enemy's base from your enemy! Remember the end of the Battle of Helm's Deep?
Costs significantly more than the average "Tower" when the lost Wisp is considered.
