Formula to calculate mob level based on how hard they hit?

[pijan]

I read this someplace and I can't remember where. What's the formula to calculate a mobs level based on how hard it hits? It was only for normal mobs in classic/kunark I think but I don't remember the details.

found something that says

"I thought it was (maxhit / 4) + 15 to determine level. 132/4 = 33 + 15 = lvl 48 mob"
