Hint 1: You may have to shrink this aura to place it. Place the auras around it first then fit this one in.
- Wave 1: Place auras, then one buff beam, switch to adept+genie, hit G. Farm mana, spam LTs. (Stack if you want - doesn't matter, and you don't have to use all the DU)
- Wave 2: Place minions to block the path of ogres (build during wave if multiplayer). Depending on your stats the minions may be entirely unnecessary. If you need minions, you can probably use them unbuffed, but if you have problems, place extra buffs for the minions on wave 1.
- Wave 3: Upgrade whatever you want. Getting mana before the monsters die will be hard; don't draw it out, finish monsters off and remember to kill%. It's okay if you don't finish upgrading by the final wave. The point is to go fast. Feel free to upgrade anything; djinn will die before they can unsummon.
This build can be done in 17-18 minutes with one builder and 4 chars in. This also works for cat farming.
Don't forget to use 'killme' to reset your Wheel o' Fortuna cooldown at the end of waves if you need to.
