I remember you! Grrrr!!!

Before they finally patched the hole, I used to enjoy running through crowds of high level monsters in dungeons to get a whole parade of them chasing me, then quickly casting a portal into the middle of town, usually next to the bank, then ducking behind the portal without going through, as the whole line of monsters walked towards me and popped through the portal and into town!

I hope they got you. Pththth!!!
