Added two quick mosnters

Hey Jordan! when making the rat I thought it might be an interesting feature to add a chance for monsters to have a special attribute such as plagued, where if the player is hit there is a chance for him to be poisoned. if you make a list and give the attributes a designated number and then add the effects a mob can have with a percentage chance of getting it (simaler to AC) and if the creature gets the attribute in the encounter its name will be prefixed with the attributes name e.g. "Plagued Rat". thanks for your time,

Eric.
