Okej it seems gemcraft owns my face, hard. tried to beat first boss level for like more than 2 weeks... and i just cant kill it in time or even make it trough wave 28/29 wich are 48 of high armor lvl dudes... no way i can do that. any hints idk maybe?
Well, be sure to outrage your mana as high as possible, and use blue gems if possible, they deal the most damage to him. You can also first beat all other levels and get as high in level as you can. Then you should be able to get passed him. I did the same way and maded it in 2 trys. Good luck.
