Gemcraft Labyrinth is not difficult at the beginning, but it gets really hard, really fast. So, "how do I get further?" I will provide a few GENERAL tips in this thread. Although I have yet to reach the fourth Epic Field, I do know what does work.
#00) Replay Early Fields You cannot pass this game without replaying. You would only gain the difference between the old and new, but you may level up. Several times, I have skipped a couple levels entirely by replaying old fields. #01) Kill apparitions Apparitions will sometimes appear. Kill it. After killing it, DON'T DO ANYTHING STUPID!!! You will only get the skill points by winning the battle.
Feel free to post your own methods. (please avoid spoilers) I will post more every so often until I run dry.
