Description from the Dor Un Avathar
Magic-Like Abilities are treated and activated in all ways as per the spell listed, except they do not cost magic points, do not require a free hand, and are given a set number of uses. Magic- Like Abilities cannot be used in Anti-Magic areas. Magic-Like abilities can be used with the Extension spell, if a Monster has access to both.
