DM trinket books

Has Bliz increased the drop rates on these in the last week, or have farmers found a way to get a lot of them. At the beginning of last week, the priest book went for 120g.. now it's down to 20g with at least 5 people selling them in IF at all times.
Same goes for all the other books.

Anyone know what's up with this?

Word on the street is there's a teleport to the boss.

figures...

I heard there's a spot you can stand where the king will evade (not attack you, but not heal to full) and you can just shoot him to death w/ ranged

You can also vanish pull the king.
