Maxed out all flak kill island with electro in the middle, earth/ice in back…
Maxed out rage drain before that with another ice flak and either a cannon/storm/ice for shielded dragons/sanding/entrapping/white cloaking dragons/elemental resist dragons.
You won’t kill the rage drain. And then you will get annhilated when all the flaks interact with each other optimally/synergistically.
How do you beat it?
