When triggered, all characters within a four square radius randomly switch consciousness, no Saving Throw allowed. The characters are still all themselves, even though they look like other people. They retain their old skills (including prepared spells), but must now contend with new bodies, including new HP and possibly Saving Throws. A successful Dispel Magic or Remove Curse spell on the whole group at once will restore the characters to their rightful bodies, but until then, they are stuck. Optional: This is especially amusing when a monster or enemy is one of the switched characters!
