This is probably a really silly, obvious question but I've looked everywhere and I can't seem to find an answer. It doesn't even tell you when you are in the armoury picking out your weapons :(

Edit: I figured it out. It told me when I just kept clicking on weapons >.<

in case anyone else wants to know the answer for future reference, the answer is 8 weapons.

eight weapons and as many scrolls as they have Alchemy points for.
