Goddamn Bats
From Tel'Laerad Wiki
In Wesnoth, these GODDAMN BATS. ARGH, you don't even know.
YOU ARE A JERK FOR USING BATS. A JERK.
- The exception to this rule of ultimate jerkdom is achieving Judge Dread. That is, simply, leveling a sole Goddamn Bat all the way to its level three incarnation, a Dread Bat. This is ideally the Undead player's sole bat the entire game, and one used for actual combat rather than village dickery.
