There is a steel battleaxe in Ironbind Barrow, (save before entering as it sometimes doesn't appear), near the throne in the final Boss chamber. It has the very rate enchantment Fiery Soul Trap. Once this has been learned, one can make a truely awesome soul trap weapon. (We prefer a dagger, (for the 15 X sneak bonus), dual enchanted with shock. We get 18 seconds of soul trap plus fire and shock damage.   >:-}
