I'll pose the first question. Will there be any way of getting a different wand location without attaining a wand from said spot? I ask this because some spots are nearly impossible for certain mages.

Second question, is it possible to discuss a certain type of wand or just random? I ask this because presently there may only be a need to get a sienna, for example, after it's used up and once needed it can be gotten without having to gather a black and amber before getting it again.
