Build Description
A build I came up inspired by multiple others that should (hopefully) be less confusing and more accessible to set up. You might be able to get away with ~1k stats but I found that to be inconsistent. The required stats listed are estimates.
Proton Beam obviously should be 2DU. It's there to spawn kill Spiders.
Hint 1 - This is where the most pressure will be. Keep these repaired at all costs. Haven't tried it but in hindsight, you could replace these with two Orc Minions, although Dark Elf Warriors would become even more of an issue.
Hint 2 - The trick here is to angle the Reflect Beams so that they touch the Tower Buff Beam but also cover the Apprentice towers. It's fine if you can't squeeze the Mage Minion in here.
