Invalid Hex

A Hex the Unit could not move onto due to Terrain or, for minions, not connecting to Mark. If a Minion is on an invalid Hex due to an effect, its next Movement uses the fewest possible unoccupied hexes of any Terrain to reach a Valid Hex, then uses remaining Movement to make Progress if possible. A Hero on an invalid Hex can only move off it by moving onto a Valid Hex.
