Item Drops and Finds (Pre-BB)

In my server, Freeze Standing 20 is one of the 4th job Aran mastery books that are very expensive. Hold on to it, it might fetch a pretty price later on.

Isn't the expensive (relatively) one Freeze Standing 30? Only Lilynouch and something else drops it.

I've managed to get around 4000 boxes in the past 3 days at the mushroom mini dungeon without getting a chaos drop. Out of all the boxes, I didn't get a single scroll. No def scrolls, either. Only thing noteworthy is a Henesys Skin Care Coupon which I will never use.
