Survival is easy with 1 warrior, 1 cleric, 1 ranger, and a conjuror. Make sure you get all the debuff moves. Cast all the debuff moves a the beginning of the battle, and get vampiric equipment for your warrior and cleric.... i got to 60 with this setting

That strategy has been posted before alot of times. Its in a walkthrough I made on Kong. Its on someone elses guide too. So you're the one taking the credit.
Actually after every wave, there is a preview if anything new is coming in the next wave.for eg It tells you when lead balloons appear and also tell you how to beat'em
Here's an easy strategy. First use toxicant form(40% extra dmg). then shadow blend(400%speed). then agile exposure(2xdmg). finally use withdraw to release a galactic can of whoop ass!! this works best when you have a high speed and all above mentioned skills at the max (consider using re-spec). use it when the opponent is weak. for example I used it when the colonel was reloading and i did 50k+. It has the power to dmg even shielded foes(android)
