| Effect: |
| Fills a hero's spell points to twice their maximum. Only one hero per week can use this effect. |
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.
Horn of the Abyss[edit | hide | hide all]
In Horn of the Abyss, Mana Vortex is now activated manually and can only be used by a guest hero. Additionally, AI hero allies cannot use Mana Vortex in the player's castle.
User Commentary
Be careful which hero you use to interact with your dungeon town at the start of each week, as you usually won't want a support hero doubling their mana instead of your main hero. If you have a hero garrisoned (ie: defender hero holding statue of legion pieces) you can strategically bypass the vortex doubling effect by navigating to your dungeon castle view through another town (using the right-side navigation pane).
Also, a good tactic is to equip all the knowledge enhancing artifacts on you before you build the mana vortex, as it will maximize your spell points enhancement. Once activated, you can re-equip your normal set of artifacts.
