Hiho,
i honestly dont Know how the other guys doing there maze, but i am only able with a shadow carry with withered Set and Excalibur, and 6 beavers stacked with Lucky pants, aswell as two Gibs One With messerschmidt and hades, the other One with shrooms.. i will Post a pic shortly After of my current game ..
I am not able to kill mass challenge, everything else np. In my current game i lost % from goblin :D
Go for the SAT tactic.. i've done the 2k waves on hard with the tactic. In the beginning i just use shadow until level 2000, and then place MB as soon as i get them.. You may have to play the first 200 level 2-3 times before you get enough money, but around 15b should be sufficient, but more wouldn't hurt!
Do you guys put messerschmidts on SAT in mass waves ? Cause i think its going to save a lot of money :-)
I do, and then i just send out as many waves as possible. In the beginning you can get to kill 3-4 waves with one shot if you're lucky (3 bosses). But around level 1800 i stop using the axe and start using a cactus instead.
1 tower will save you most of the time... that tower is GIB. Give him ASPD and Reaver for mass challange waves. I am currently doing a 2k wave game with a shadow that has over 26k% damage bonuses on wave 527. Also Reaver + lucky pants x3 makes for amazing farm of mass challange if you don't care about not killing them. I am also able to get over 4k bonus damage from single mob challange wave if I want to let it sit for 5 mins (Gib + 3 towers with .1 ASPD and 2x withered items).
