Underground

Underground battles are battles fought in under the ground. Certain items, followers and character traits have effects that specifically say they apply to "underground" battles.

What counts as "underground"?

 * All Underway maps (including Underway intercept battles, quest battles etc)
 * Siege battles against some Dwarfs/Greenskins settlements (particularly ones in the World's Edge Mountains).
 * It is unclear whether certain Skaven settlements, such as Hell Pit, count as underground battles.
