Can I ____?
Sometimes a player asks, "Can I [blank]?" Maybe you know such a player. Maybe you have been that player. There are many ways to answer that question, some helpful, some not so helpful, but if ever you wish to allow the supernatural to offer a guiding hand, here are some tables with the answers you just can't be bothered to formulate.
One table is based directly on the Magic 8 Ball, but requires the use of a magic d20 instead (although a nonmagical d20 will suffice). The other table requires an oracular icosahedron (although, again, a nonmagical d20 is an acceptable substitute). Choose the table that best serves your needs, but if indecision strikes, you may always resort to a random method, e.g. roll any die if the result is an even number, roll the magic d20; if the result is an odd number, roll the oracular icosahedron.
