I don't know about the Axe, but with 2HS raising the mastery is so fast, that it almost feels broken.Will try the same thing with the 2HS later after I get the axe to 500.
Looks like it's just a regular armor you buy from the shop.If your avatar is a female character will it let you use the maid outfit and such, or are those exclusive to the heroines like it Hollow Fragment?
I can check it on my copy later - I completely forgot to download that DLC.
Is there a way of displaying more than 2 palette bars at once? I looked through the options but didn't find anything.
