GemCraft Chasing Shadows 10 - Still Not Enough

Field X4 has 90 waves. I am having trouble by wave 60. I don't remember the wave count getting very much higher than that even in hextile Y, so once I beat this, I might be strong enough to deal with the rest of the game. The problem is that I might run out of fields to get XP from before becoming powerful enough to deal with this.
