N., age 10, came to me, excited, and explained how he broke 3e this time.
N.: "It is simple, really. Use the metamagic feat Explosion on the Telekinesis spell and cast it on a bucket. Explosion moves objects inside an area of effect spell to the edge of the area of effect. Telekinesis affects an object, has a radius of 10', and travels with the object it is cast upon. So now that bucket is travelling at infinite speed and if it hits something, does infinite damage!"
