Surviving on Impossible

[dli2k3]

I'm also playing a mage on impossible, I'm lvl 10 and started killing things on Freedom Islands. For the turtle, I found by accident an easy way to defeat it by sacrificing the useless beginning units. I had 2 royal thorns at the swam and brought them into battle with the turtle due to their high hps and I found out that the turtle would always attack one of the units in front of it. So by using the germination ability on the thorn, I generated some thorn which can use the plantation ability to grow other thorns and each new thorn gets the plantation ability again, so in the end, I had like 10 thorn units, some of the with only 1 thorn planted in front of the turtle and each time the turtle kills one, I grow it back...In the mean time, I just blast it with ranged units and spells...
