I thought the whole point of these, specifically for Ragna, was to find a way to do 5D x N or something else to get heat for DbD where he couldnt.
If Fluck's example above works, then that's just using 50 heat like normal, but probably more damage. It won't jump that high, but it's still silly and other characters may abuse this more than others. Idk I just don't like the idea of it.
