A combat level is you overall fighting skills. (attack, strength, defense, hitpoints, magic, ranged, and summoning all contribute to your combat level).
What you attack should be based mainly on your combat level. Try to attack creatures that are a bit over half your combat level. That way, the creatures will continue attacking you (if you choose an aggresive type) - as soon as you kill one, the next one starts to attack you. If the combat level of the creatures you attack is too high, you will need more food.
