There are several pieces of advice I could give you on surviving an encounter with a ditch witch: avoid her ranged attacks, beware her cursed bone kris, attack her with fire but not cold. But the biggest one is this: do NOT under ANY CIRCUMSTANCES call her a "ditch witch" to her face. Just keep it to yourself! Yes, yes, of course they are members of the foul Grep'lan Wiccan Order of High Sorceresses and Enchantresses Who Bask in the All-Knowing Light of Kordashim The Moonseer. But who has the time? You get halfway through saying that and there's a bone kris through your eye.
