Build Description
Auras and traps should all touch beams. Can do more reflection beams and traps with the left over units.
Hint 1: These are placed on the wooden ledge east of the crystal, it hangs over the spawn point. Place the auras as far on the ledge as possible. Needed these to deal with the shit ton of fish wyverns. The mage minion doesn't have to be on the ledge.
Hint 2: The western most archers take the most damage. Could try orcs here.
