If you haven't you'll wonder why the book is out of order and doesn't work.
-Player must be targeted with a ranged touch attack (like Disintegrate)
-The caster *critically fails* (rolls a 1) on that attack
-The player succeeds on an untrained ranged touch attack of their own
I would be amazed if this ability triggered and succeeded more than once in an entire campaign unless the DM went out of their way to target the player with it.
Oh, and "ranged touch attack" only appears in the Bestiary once lolololololololololololololol
