Fear raging barbarians wielding two-handed melee weapons, for they shall surely slay you with the ease of a red-hot knife going through a stick of butter. Fear giants wielding their customary weapons against you, for you are squishy and go splat with a most satisfying "SPACK!" sound. Fear being on the wrong end of an Alexanderian phalanx and its ranks and files of longspears, for you make a good pin cushion and they make good pins. Fear all of this, unless you have Spring Attack and some way to exploit the low AC scores that such combatants often present to you.
