Dark Tower/1.03

Level 5
Dark Towers are dissatisfying large buildings. Fortunately though, they don't offer much that would provoke a need for more of them. The Runes don't really delay tiring and only a single new rune per level becomes available, allowing you to steadily research them without being overwhelmed, and Wisps can't be sent to the mines, so you wont be spamming them. Although Wisps can become Ancient Wisps, producing them between keep upgrades is more than adequate as the Dark Elves don't rely as heavily on Ancient Wisps as the other Elven races due to the access of actual minefillers in the form of Thralls and Zombies. Because of the building's large size and long view range, it can keep a watchful eye out for pesky opportunists that have found a gap in your defenses.
