If a Caster is hit while casting he/she has to make a concentration check. Does this also apply to any of the following and could you point out in what book and the page the answer came from.
1. Extraordinary abilities?
2. Supernatural Abilities?
3. Spell-like(or Psi-like) Abilities?
Thanks in advance.

Spell-like (and psi-like) abilities can be disrupted like spells (and powers) can. Supernatural and Extraordinary abilities cannot.

Extraordinary Abilities (Ex)

Extraordinary abilities are nonmagical, though they may break the laws of physics. They are not something that just anyone can do or even learn to do without extensive training.

These abilities cannot be disrupted in combat, as spells can, and they generally do not provoke attacks of opportunity. Effects or areas that negate or disrupt magic have no effect on extraordinary abilities. They are not subject to dispelling, and they function normally in an antimagic field.
Spell-Like Abilities (Sp)

Usually, a spell-like ability works just like the spell of that name. A few spell-like abilities are unique; these are explained in the text where they are described.

A spell-like ability has no verbal, somatic, or material component, nor does it require a focus or have an XP cost. The user activates it mentally. Armor never affects a spell-like ability’s use, even if the ability resembles an arcane spell with a somatic component.

A spell-like ability has a casting time of 1 standard action unless noted otherwise in the ability or spell description. Spell-like abilities cannot be used to counterspell, nor can they be counterspelled. In all other ways, a spell-like ability functions just like a spell:

Using a spell-like ability while threatened provokes attacks of opportunity. It is possible to make a Concentration check to use a spell-like ability defensively and avoid provoking an attack of opportunity. A spell-like ability can be disrupted just as a spell can be. Spell-like abilities are subject to spell resistance and to being dispelled by dispel magic. They do not function in areas where magic is suppressed or negated.
Supernatural Abilities (Su)

Supernatural abilities are magical and go away in an antimagic field but are not subject to spell resistance, counterspells, or to being dispelled by dispel magic. Using a supernatural ability is a standard action unless noted otherwise. Supernatural abilities may have a use limit or be usable at will, just like spell-like abilities. However, supernatural abilities do not provoke attacks of opportunity and never require Concentration checks. Unless otherwise noted, a supernatural ability has an effective caster level equal to the creature’s Hit Dice. The saving throw (if any) against a supernatural ability is:

10 + ½ the creature’s HD + the creature’s ability modifier (usually Charisma).


EDIT: Oh sure, make me check the books :smalltongue: Monster Manual, page 315.
