Post your best follower moments and worst follower moments.
I'll start with something I just had happen in a game with a level 19 necro. I'd been putting off using slaves for a while because I didn't feel like starting with that hassle til I found good corpses, but I got my hands on 2 scrolls of familiar summoning. I went to the small cave and got a Kiri-run and a Giant Rust Monster. They both proceeded to chew through the SMC and UD with no problems. But on level 7 I pool sipped and got permanent invisibility. For some reason, Rusty had no problems following me, but Kiri kept getting confused. I also had teleportitis(controlled) and this was somehow resetting his AI. Anyways, I got annoyed and just went to clear a few rooms and go grab him after. In a shockingly short span of time he forgot about me, and was hostile when I got back. After blasting me with a spell for 70 damage he got annihilated in a flurry of 7 attacks by rusty.
Rusty then went on to clear the Darkforge and kill Kherab by himself, but was almost killed by the crown of science room. It had a blindness trap and multiple fireball traps, so he followed me into the crown room, and then proceeded to stagger from trap to trap for like 20 turns til I got desperate and teleported him, hoping to catch up with him. I had to throw like 7 potions at him to get him back to stability.
Anyways, anyone got some funny stories about followers?
