Your slippery ways allow you to evade a damaging blow.
Prerequisite: Dex 15, Small size or smaller, improved evasion.
Benefit: The effects of this feat resemble those of the rogue's defensive roll, but you can use Scramble to avoid a potentially fatal attack entirely. Once per day, when you would be reduced to 0 hit points or less by damage in combat (from a weapon or other blow, not a spell or special ability), you can attempt to scramble our of the way. This requires a Reflex saving throw (DC 10 + damage dealt). If the save is successful, you avoid the damage entirely. You must be aware of the attack and able to react to it; you cannot use Scramble if you are denied your Dexterity bonus to Armor Class.
Special: Since you cannot normally make a saving throw to avoid the damage from a blow, improved evasion does not apply. That is, you cannot save twice against the same attack.
