1.) To answer a lot of chat in PoK - the gargoyle tooth gets turned into the Gargoyle next to the OT stone in PoK. This will enable the Gargoyle Shroud.
2.) To answer my own question, there are 2 claim items, which are received by typing /claim #6 or /claim #7 for each of the items, so, you don't have to worry about giving the wrong item to the wrong character. (Thanks, Fhrugby, and Faromor.)
3.) I played for about 3 hours last night, as different monsters. Noone on my server "dinged" a monster level (or missed the question in General), but I have to guess that monster progression is probably along the same lines of XP for an AA. As I stated last night, if they were "easy to get" all of the "ubers" would have had every monster unlocked on the first night, and the "magic of the new expansion" is already lost - it has to be something worth working for, and progressing to slowly - nothing worth having come without patience. For those without the expansion, there is no XP bar while you play as a monster, which is very frustrating, but the Play as a Monster feature is a cool concept, nonetheless.
4.)The monsters seem to have their own AA set of abilities, based upon "Monster Points". Basically, depending on the level of monster you choose to create, if you open the AA window, you already have a set number of Monster Points (AA's) you can give them. You can save these ability sets, or recreate them every time you switch forms. I am not sure if it was based upon my level or not, but the Gargoyle had 99 monster points to begin with, while the other monsters had somewhere between 70 and 85.
5.) NOONE, thus far, seems to know what the evolving items drop off of, or who you must speak to in order to get the first piece. If anyone knows something about these, please, let the rest of us know.
Hope this helps!
