From the SRD:
Ability Drain: This effect permanently reduces a living opponent’s ability score when the creature hits with a melee attack. The creature’s descriptive text gives the ability and the amount drained. If an attack that causes ability drain scores a critical hit, it drains twice the indicated amount (if the damage is expressed as a die range, roll two dice).
Yup.From the SRD:
Energy Drain (Su): This attack saps a living opponent’s vital energy and happens automatically when a melee or ranged attack hits. Each successful energy drain bestows one or more negative levels (the creature’s description specifies how many). If an attack that includes an energy drain scores a critical hit, it drains twice the given amount.
If a melee attack causes a saving throw every time it
damages an opponent (a monster with a poisonous bite, for
example) and the attack is a confirmed critical hit, are two
saves rolled because there are two damage rolls?
A critical hit doesn’t deliver any extra poison; however,
there are special attacks that do have extra effects with critical
hits. These include energy drains, ability drains, and most kinds
of ability damage that are not dealt through poison. See the
introduction to the Monster Manual or Chapter 3 of the
DUNGEON MASTER’s Guide.
Scion said:Is the second 20 necissary for the example? or just to make sure it is a crit and hits?confirmation only requires a successful hit on the confirmation roll after all.. Just making sure!
