Just thought I'd throw this in, a brief video I made of my cycling the Gigantic Spirit Viking map that you may want to add in the 120+ training section. (which is, apparently, coming soon!)

Embed if possible? XD
Just to chip in a little more, I personally
never use reaper during training, I don't even have it hot-keyed and I very rarely use dark shock. My training mainly consists of casting Blow+Tele but I do tend to use Finisher at bosses as the 20% defence reduction comes in handy.
