If you draw any of the CURSED tokens, you must equip it/them during your next in-person run. It is possible to suffer the effects of more than one CURSE at the same time. E.g., if you pulled CURSED Fork of Gluttony and CURSED Mirror of Pride, you would be under the effects of both curses. However, if you pull the same CURSED token more than once, the effects of the duplicated CURSE do not stack.
If you received multiple CURSED tokens with the same name, you must equip one during subsequent in-person runs until they are all depleted.
These are, of course, completely optional--they're just a bit of geeky fun. You can negate the effect of one token if you deploy a Scroll of Remove Curse, Censer of Sacrifice, Fey Bread, Potion of Bliss Stout, Potion Moon Veil, or a Scroll of Remove Woe. The tokens used to negate the CURSED token should be discarded.
Once you fulfill or negate the CURSE, you may keep the token as a keepsake. These completely expire at the end of Gamehole Con 2022. No CURSED token may be used in an adventure--in any capacity--after 2022.
