An ancient feature when playing as the Swamp faction. The second-to-last diagonal move costs 100 movement points (assuming there's no pathfinding, of course). I even came up with this as a question for one of the old quizzes. Personally, I've been using this trick for a long time and regularly.
p.s. This feature doesn't work on other terrains with movement penalties.
Wow :eek:
If you add up all the moves I could save, you could cross the entire map 10 times, just like a young Reddit user :smile35:
