The greater basilisk appears identical to the common variety, save that it is larger, having a body length of about 8 feet with a 7 to 9 foot long tail and weighing between 400 and 750 pounds. The skin of the greater basilisk is toxic to the touch, such that any living creature bitten by one or who touches one with bare skin must save vs. Poison or die. This effect persists even after the monster is dead, typically for about 2d20 hours; the only way to tell if the effect has subsided is to touch the corpse, an obviously bad idea.
