I know we all hate bieber but please don´t rate it 5 just because of that... the are waaaay better games around that really show the effort of the developers by the cuality of the games so please don´t rate it 5 just of bieber hate
+ if it helps you please... Best skills to buy: the 3 attacks (as they don´t spend magic) Ligthinin strike and thunder dome (devastating, can kill at least 6 enemies of the highest levels) fire ball and fire wall (specially good against bosses if you can push them against a wall) and heal.
easy way to level up... go to F12 and activate double amount of monsters, 15 extra waves, armored only waves and all te battle traits except higher monsters armor... when on the game buy the red gems and start to put them in the towers that are already created and wait =) more than 3k experience due to the 4.52 multiplayer hit + to keep it alive please
100 life points left to kill last guy and suddenly a 10 year old girl came and to restart the game and it won´t respawn!!! noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo
