I must say, I've never seen that one. That's pretty impressive. Not quite as impressive as the attacks that could wipe out the entire cosmos due to dealing more hitpoint damage than the number of atoms in the universe (by several orders of magnitude), but still amazingly elegant. It is strange what happens when the old 3E char-op boards got bored of inflicting infinite damage, and just chased "largest quantity of non-infinite damage". It taught me new things about advanced mathematical notation.dont forget the locate city bomb:
No, this is how 3E works. 4E addresses this kind of exploit (which were rampant in 3E) and for the most part removes them completely.
There was a lot of rule stupidity in 3E. A lot. Look up Pun Pun or the Omniscificer if you so desire. Creating a being with infinite stats became a 3E subgame.
(what was the function of a codpiece again?)
My general way to handle Bag of Rats situation.
