Quickness (Su) A wither worm can take an extra move action during its turn each round.
Wither (Su) The flesh of any living creature hit by a wither worm's antennae attack withers painfully. The creature suffers 1d4 points of temporary Strength damage, and must make a DC 13 Fortitude save or be stunned for 1 round by the resulting pain. Temporary Strength damage functions as normal Strength damage, except a character heals temporary Strength damage at a rate of 1 point per hour. The save DC of this ability is Constitution-based, and includes a +2 racial bonus.
