It would be interesting I think if we could study Teleport with error to a bit
higher than we can train Teleport without error. Maybe 40/60/80/100/100
instead of 20/40/60/80/100. That way there would be an (evil) encouragement to
use that spell over the real thing at least for the large majority of us
without full nav levels, instead of only being a small extra exp cost for
training teleport without error, as it is now.

Just a dumb idea I got after failing 40% tele w/o error a few times.
