Mana Vortex
Building cost: 1000 
.
Buildings required: Mage Guild.
Mana vortex is a special building available in Dungeon. It doubles the maximum amount of spell points a hero can have and fills them to this new maximum. Only one hero per seven days (refreshed at the beginning of the week) can double their spell points. Additionally, if there are two heroes in town, only a garrisoned hero (not a visiting hero) can receive this bonus. This means that, if the bonus is available, the mana vortex bonus will go to the garrisoned hero once the player opens the town menu. AI never builds mana vortices.
