Oh. Looking back, I probably hyped her Cursecraft way too much trying to sound dramatic.

To clarify, her curses, while old, still don't have nearly enough priority to do much to Servants beyond cause a mild inconvenience. The wording, particularly around the lines "While all of these could be resisted by Servants with strong Magic Resistance, or Masters provided with adequate defensive measures, for the unprepared and isolated within the labyrinth of the Witch's Mansion, they could spell instant death." were kind of vague on that.

It IS a major threat to Masters, but only if they're not careful, since most of her curses are used as traps - curse gas hidden in golems which is released when they break, wires placed in the path of unwary enemies, crow quills displaced into the area around them to strike, etc. Usually, the curses also require consecutive applications to bring down a target, with each one that hits softening them up a little more for the others to take effect more easily. So, it's also not "instant death," as I so mis-leadingly put it in trying to sound dramatic. I'll go back and change that now.

Oh, and let's just say there are ways around the Bounded Field other than just strolling in. I just didn't include them here because I didn't want to give away my weaknesses to everybody. :P
