NO, the pet must be +9 LvL higher than the raid boss.
it used to be an exploit like this in retail server but they fixed it.
you take a pet like a baby cougar.. EXP the shit out of it so it gets to LvL 80
then you cast Blazing or Freezing skin on it, you order it to
hit the raid boss ( Lower of 71 LvL RB ). On first hit the pet
petrifies and doesn't die, but it has like 30 Pdef so each time the raid boss
hits the petrified pet it hits for 20k damage. the petrified pet cannot die
but it returns ( because of the buff) about 4-5K damage back to raid boss.
because of the returned damaged the raid boss keeps hitting the pet untill
it suicides. FIXED on Retail.
yeap i know its fixed but trust me u can do it with any lvl pet the point is to get petrify and to have low def
