I AM LVL 12.000 AND THATS ALL BULSHEVICK.
you must have 3-6 ( Chain-Shock-Mana ) gems in traps / amplifiers around them with same gems and mana every second gem in amplifiers / keep throwing mana gems in to amplifiers with mana gems and you ll have 250.000.000 mana pool before wave 60 – 90. So you can win the tougher faster easy in 20-30 min all 1337 waves. And when you go full forward use ( Chain-Multiplier-Sloving blue ) in the trap with as many as posible amplifiers around it.
