The rules will bend to accomodate anything that is obviously and undeniably neccessary, eg fireproof blankets since I can't teleport or dig without a flammable item. D:50 is going to end badly, though not necessarily because of speed; having no food and no corruption removal or scrolls of peace will be a bigger problem.
D:49 seems (from past drakeling wins) to have a cap of -100; if I do the quickling tree, I will be fast enough for that to be non-fatal.
