My endless wave game.
This is my endless wave end screens. I had about 590m when I first built my Sat around wave 320-330. The wolf picture was just a stat test.



A relatively simple field. Note that the herb witch between Knus and Balu has Hades helm with the full wither set. Her speed is increased to 0.2 seconds per shot so she can amplify the damage on an enemy quickly. All of the Gibs have 2 item+ 2 mushrooms wither set to constantly boot back some enemies while slowing them down. Beavers have mushrooms on their inventory (originally 7l boots). I completely forgotten I had an elvis in that corner...
Balu has Excalibur, one Blade of Darkness and two cacti to ignore almost all of the enemies' armor. That is probably why his average damage looks rather small but between ignore damage and amplify, I had no troubles with bosses/horseman/challenge which what Balu usually has problems with normally.
I equipped her with 2 magic pants and 2 mushrooms. Each attack she is virtually guaranteed to eat a mass creep.
So basically while my carry tower is pretty well fed, my support towers was doing their work allowing Balu to take more damage. The other towers were to impede the enemies' progression. Dark Forge is mostly to hit level 99 and start spamming keys once he reaches lvl 99 thanks to Ganesha/dark item which jump started everyone else nearby.
PS: The 1000 wave horseman died in one hit.

The damage is very low for a 1k round, in fact less than half of what my Balu was and he was low as it is, mainly because his damage doesn't directly scale upward like some other carries. The reason why he worked out so well is because, unlike most towers, Bear Hunter is constantly being useful even when there are no enemies in range. In this case, he is constantly placing traps. This mean he is always "attacking" even when no enemies are in range. Think of it as the scarecrow concept on steroids (given the fact that scarecrow has a cap on stored crows). As one would expect, fliers gave some initial problems but not for too long. The biggest problem is actually because of the treasure goblin and it is because of the wither set bug which sometimes causes him to clip through my tower and bypass past my kill zone. Due to this, I had to use Hades Helm to start covering the outer rim instead of the 3 squares.
At 0.1 seconds per attack, the Bear Hunter can lay down 50 traps in between delays of each wave and that is not counting the time it takes for the creeps to approach the traps though you are stuck with a lower attack speed until near the end but anything below 0.5 second suffices. To reduce the number of traps it takes to kill a unit, units are often amplified though this only works on bosses/challenges/horsemen since the wither set proc may push the amped target behind another creep which will consume more traps to kill.
