[1.2.335] Guild Overhaul

Umm...maybe those are for the Hot Time/Love Letter event.

Spadow covered the event on his blog.

These 60% scrolls are new and different from normal ones. If you look at them it looks like they work on all sorts of different weapons like the 50% 2 handed weapon scrolls GMS has, I think Spadow would have said something about these special scrolls instead of referring to them as just '60% scrolls' which implies they're the normal 60% scrolls.
