Touch Attack of Opportunity

[DarkPhoenixx]

Can i deliver touch spell as attack of opportunity?

Quote:

A monk, a character with the Improved Unarmed Strike feat, a spellcaster delivering a touch attack spell, and a creature with natural physical weapons all count as being armed

Does it mean i threaten the squares around me with touch attack?

[Majuba]

Yes, IF the spell is already cast.

[Nefreet]

Yes. You must already be holding the charge, though.

That is what i thought. Thanks :)
