Impossible Warrior challenge

[garzahd]

My mage only got to level 6 on Impossible so far, but I have a funny story about the turtle.

The turtle's melee targeting strategy seems to be "whichever target has been in melee range for the longest amount of time". Which can be exploited as follows:

Bring 3 stacks of ranged units, 1 stack of Thorn Warriors and 1 fast-moving throwaway stack. Charge in with the fast stack and get it killed off so the thorns can spawn extras. But make sure the thorns move into melee range before spawning. Then, a couple rounds later when the parent stack of thorns is dead, the child spawn uses the parent's corpse to make more thorns. Rinse and repeat. The turtle will always attack the stack that has just used its spawn ability. And, although the stack size reduces each cycle, it always rounds up to 1.
