Suppresses enemy commander effects within 6 squares.
Characters within 6 squares cannot receive the benefits (or the penalties) of enemy commander effects until they move out of range. An enemy commander within 6 squares has its commander effect suppressed until it moves out of range. (It still counts as a commander.)
A character who starts its turn outside this range and whose speed is modified by a commander effect continues to move at that speed for the rest of its turn, even if it comes within 6 squares of this character. Conversely, a character that begins its turn within range cannot have its speed modified by an enemy commander effect for the rest of its turn, even if it moves farther than 6 squares from this character.
