Ancient Amuletor (UP)

I found this to be the hardest trophy in the game because there are several spots that are hard to see where enemies can basically sneak up on a crystal, combine that with the summoner enemies and this one can be a bit tricky. I found the best option to be using the gunner and constantly teleporting from tower to tower as that is the only way on this level to ensure you can see all the enemies. Your two most used towers will likely be those closest to harbor but you will likely use them all. The good thing here is the wooden man traps can be used to great effect to protect the crystals while you are bouncing around. Don’t let a crystal die and you’ll get the 3 stars. This can be done with any character and even in multiplayer as long as you are solo.
