Pluto Hall

The Undead are strengthened by this resevoir of energy, and craft their greatest undead Magicks here.

The Pluto Hall was introduced in the Babel Expansion. It can only be built in Undead towns, and the spells it produces only apply to Undead Heroes, and only to Undead units carried by Undead Heroes. As with all racial spells, once spells are researched in the castle, the current owner of the castle will receive the bonuses automatically in battle.
