Don't hover-sword-burn before you can walk
This sort of trickery is best left to the very experienced and the extremely foolhardy. Used by a master, these advanced techniques could mince 50 demons an hour, but there are a few downsides:
- The flaming sword attracts fire-demons
- The angel-wings attract demons who are after a new duvet
- The hovering attracts health and safety officials (non-demons, but pretty nasty).
With this number of demons nibbling at you, the gigantic, blind ooberdemons will sniff you out and begin mental digestion of your abilities.
