Joko's Ninja Exchange rewards!

From Firebrand Badges...?

That's a little awkward, considering Firebrand is associated with Magicians and magic. I would think that all Taos come from either a drop from Nightshadows or as a reward for exchanging in their badges. Or perhaps each different piece of Tao comes from a different set of badges?

Tao of "Spirit", getting from a mage-like-mob makes sense to me.
