Whenever a creature takes damage from a bandersnatch's tail slap attack, quills, or quill defense, that creature must make a DC 28 Reflex save or a quill lodges in its flesh, causing the creature to become sickened until the quill is removed. Removing one quill requires a DC 20 Heal check made as a full-round action. For every 5 by which the check exceeds the DC, one additional quill can be removed. On a failed check, a quill is still removed, but the process deals 1d10+6 points of damage to the victim. The save DC is Dexterity-based.
