Proportion of mobs stats are same as bosses .
HP: 120 000
DEF: 2 016
HP: 179 998
+High DEF low HP ,thats why mages used to aoe golems ,because they had a low def which is insignificant while ur atacking with magic.
+Harpies got average hp but very low magic resistance.
HP: 233 025
HP: 150 000
+High HP low Def ,thats why melees used to prefere doing trolls/apos over golems/harpies because for melees low def mobs are easier to kill.
My 5 cents about this issue
