100 different uses. all random
Almost completely useless so far except to confuse people. Current discovered uses. Create a 30ft well below someone. Create a banquet. animate objects. Turn things blue or red. Create an owl-bear. spawn a skeleton rat. hit everything within 50ft with magic missile. ability to walk though walls (and i assume other objects as well). create a “portable” fireball. remove hair from the body of the victim you pointed it at. and create a rug under victim.
Lyle only agreed to help if he got the first magical item discovered. That happened to be the random rod. After try to kill sleeping gnomes the only thing he managed to do was animate a morning star (thrown out window of a ship). Spawn a skeleton rat (same). Make them a banquet and remove ones body hair.
