- If you move any troops off of that domain (on is fine) then the invisibility goes away.
- Fog of war setting & the enemy owning domain next to the domain in question does not matter.
Ambushes: Tying enemies up by placing ambushing troops:
- If you place all your spoiler troops at one location & don't move any troops off that location(whether they be the original spoils troop or troops you add latter) Then that domain is a ambush spot.
- You must choose to place all the troops your getting from cashing in one spoils set, at that location only.
- Any time a enemy attacks a ambush they can only attack that domain & nowhere else the rest of the turn.
- After a ambush is sprung that domain is no longer ambushed. (unless you set up a new ambush)
Benefit to the game:
I think it would be fun setting surprises for the enemy. Might add some strategy too.
