Special thanks to BleedingSoul & KarenRei for some of the creature stats and formulas

Order below is a general guide to creature difficulty. Depending on your stats, armor, weapon, etc you may find that the sort order isn't 100% for accurate.

Attack / Defense are not the only determinants for creature difficulty.  The formulas used are player discovered and though consistent are not proven.

Be advised that unknown attributes like physique and coordination also determine difficulty.  Some creatures with lower Atttack / Defense might be more difficult due to higher Physique / Coordination.
