-the "unlimited exp bug" also works in esmereldas house, when you walk between the 2 rooms
-Sometimes when you go to Arhu he is a cat (I don't know whether this is intentioned). here comes the trange thing: several times there was Arhu as a man and beside him he as a cat O.o
-Arhu sells an exclamation mark which seems to be a weapon (although he sells it you can't buy it)
-sometimes he sells more than one exclamation mark item
The EXP bug I believe is tied to the change in companion coding. I think it sees them as player generated characters and they trigger things like the EXP bug and the Cook's chicken dialogue.
The Cat Arhu is listed in the patch notes as he will sometimes appear as a cat. So it's at least intended at this moment.
I have explained in the bug report thread on how to obtain that lovely, over powered ! weapon.
