One of the funniest things happened in all of my Runescape years. I killed an autoer, and here is how it was done!
I was training at the guards in edgeville on my 56 pure. His stats are 56 attack, 30 defense, and 81 strength. Training along with me was a 72 character with full rune and another 65 with full rune and chainmail. I noticed the 65 was autoing, because for over an hour he would not talk, and got most of the guards right away. Slowly, the guards hitting low hits took their toll on him, and he was down to less than half hitpoints.
I took a bow and arrows out of my bank. With the help of the 72, we trapped the autoer inside the gatehouse. I then ranged the northernmost guard while I was standing in the wilderness. The guard obviously attacked me, and I fisted it for three rounds.
I then ran, and the 72 blocked the guards retreat to the south, so the 72, the guard, and I were all in level 1 wilderness. A noob came along and let the 65 out of the gatehouse. He immediately entered the wilderness and killed the guard I had trapped. I then left clicked on him, and hit 15, 19 dead.
I got his ammy and rune large helmet.
That should be a lesson for those of you who should try to auto in the future!
