Random Utterance (Su): Every round as a free action, amid its garbled babbling, a garbler speaks one word of power. This utterance affects one random target within range.

6Preternatural clarity (reversed)

Reverse Utterance (Su): As an immediate action, a garbler can reverse any utterance from the lexicon of the Evolving Mind that it hears spoken within 60 feet. The target remains the same, but a garbler uses this ability when reversing an utterance would be advantageous to it. Thus, a truespeaker seeking to harm the garbler with a reversed word of nurturing might inadvertently heal it instead. A garbler instinctively knows how best to reverse an utterance and will never reverse a beneficial utterance that targets it.

Immunities: A garbler has immunity to gaze attacks, visual effects, illusions, and other attack forms that rely on sight.

Skills: A garbler never needs to make a Truespeak check for its utterances

A garbler is blind, but it can sense foes nearby using its blind-sight. Once it detects prey, a garbler rushes to attack the nearest creature with its many gnashing mouths.
