D&D + Marvel + RttFF, random glyphs. 24.73 x 21.85 inches.
The two glyphs may be any combination of power glyphs or treasure glyphs. It is suggested that treasure glyphs be played power side up, but they may also be played symbol side up with either the "nothing happens" trap or the "roll 3 attack dice" (a.k.a. GenCon 2010) trap.
