Real weapons are banned. Cosplayers or costumers whose costumes include replica weapons such as a machete or sword may have these items inspected to assure the bladed weapons are not a threat (ie: sharp or dangerous). Crossbows and/or guns must be fake or disabled from working, and again, available for inspection.

If you arrive with any of these items they will be confiscated until you leave the convention – or you may take them away.

If in doubt please email us, safety is of utmost importance to us, as a zero tolerance stance will be taken.  If you are caught illegally carrying a knife or a gun, even an imitation one you can be arrested and prosecuted!
