Getting 1 Trillion EXP in one hour (GemCraft - Frostborn Wrath)

Here you can see my current super efficient tactic to get EXP superfast on a rather tricky map. This level has the advantage of the lack of non path building place. This removes the effects of the dark masonry trait.
As you can see i could have beaten all waves but i lost intentionally because the dropped fragments are always dispersed at the latest waves. Each win adds lots of more waves. Farming fragments would need more and more time if i go to the win. Gaining XP can be done better with enraging early waves.
