Okay, I was just fooling around in the Battledome while checking iDB for the information. I selected Robo Grarrl as a challenger, tried to steal from him and for some reason, I stole a
Life Giver, which isn't even on the list of weapons which the Robo Grarrl has!
By the way, please move if I didn't post this in the correct forum.

How is it even possible to steal a weapon from your opponent which he or she doesn't even have?
Maybe he doesn't own an Amulet of Life, but owns the Life Giver instead. Which would be a mistake to report in that one other thread that never seems to get noticed (since I reported that one of Turmy's weapons blocks Earth, and that still hasn't been updated), assuming you could confirm that he uses Life Giver against you rather than Amulet of Life.
I'll try to fight him a couple more times to see if it shows up as
Life Giver when you have it, but
Amulet of Life when he has it.
EDIT: I stole the
Amulet of Chaos, but when I used it and it said I accidently froze myself, I'm not actually frozen... It seems to have done nothing because neither me or Robo Grarrl was frozen, and I was not healed by 2 HP either. Oh, and it didn't take away any health from either of us.

Odd and interesting. I'm going to look into this too. I've fought him a bunch and never noticed any of that happening to me.
I think I can now confirm that the Robo Grarrl uses a
Life Giver, and not
Amulet of Life. If anyone who can change the iDB website reads this, please fix the error.
