This is an easy to build and harmless looking trap but it has killed quite a few people. By the way, this is built in red's perspective. Red---The enemy climbs the wall like a normal door ladder and gets hurt by the spikes. Good Things. Fairly quick to build. Fairly low cost. 260 wood 120 stone. Bad Things A well placed bomb can destroy it. About 3 knights working together can get though the trap. Not very stable.
