Funnily enough, these work very well in the Beta. https://forum.kag2d.com/threads/265-most-inexpensive-trap.3113/ Instead of the trap bridge, use a trap block and spikes in the bottom, also placing a bridge upside down, (press space twice to rotate the block 180 degrees), prevents the enemy from jumping back out: Spoiler These work very well against a small tower as well. Spoiler Fairly cheap and effective, spikes near the door stall knights from attacking the door because they have to destroy the spikes first. Happy spiking! *Note, I found an empty server to make these on but the map was mostly destroyed... Sandbox isn't implemented yet either.
