Gemcraft Chasing Shadows | Vision Field V4

Notes: The three level 2 dual gems near the orb are there to attack the shadow fragments that the shadow will be throwing at the orb from time to time to steal the mana. Also, I am fairly sure that dual gems have higher attacks per second than pure gems do. When I did not use them in previous trials, I died a lot. It seems necessary. Also, I'm not sure if using dual gems in the amplifiers is optimal, as the first time I beat V4 I used a mix of 3 green gems and 3 yellow gems. The most important part would be the transition from the Grade 5 Gem to the Grade 6 gem. In the last few waves you will be close to getting overwhelmed and when you are upgrading, keep a mana buffer, as some of the monsters will get through to your orb. I do not believe that being premium or not matters in the vision fields, but for the record, this is non-premium.
