i tested this many times and you could if u want to, first get a monster with about 15000 health or so, now have someone hit a 9999 on it, it may say 9999 but use the spell libra on the monster now and check how much health it has if yoor people are a high lvl then it probably did over 10000. I did this on an azer and it was one hit (party all lvl 99)also it would be nice if someone could go on wifi for once, just saying....
