HAMSTRING[[Category:Skills Usage: hamstring <target>
Duration: N/A
Hitting your target's achilles tendon with a slashing weapon will result in
crippling your target for some time. (The amount of time depends an how
well you've learned hamstring as well as your level and tier.) A crippled
person will move at half his speed and their damage will be substantially
lowered until they recover from the effect. After the effect wears off,
you will not be able to hamstring the target again until some time has
passed.
