List of Creatures by Experience to Hit Points Ratio

An important factor to consider when hunting to gain levels, more so for a Druid or Sorcerer when hunting creatures that they can only kill with runes, is the ratio of Experience points earned by killing a creature to the amount of damage you have to inflict on the creature to kill it.

There are, of course, other factors to consider, such as self-healing of creatures, damage dealt by creatures requiring frequent healing or the amount and quality of loot dropped by the creatures, that determine which ones, in reality, are most economical to hunt.
