Kroot Hunting Pack

Each time a KROOT model from your army makes an attack, add 1 to the Hit roll if the target of that attack is below its Starting Strength, and add 1 to the Wound roll as well if the target of that attack is Below Half-strength.

KROOT models from your army have a 6+ invulnerable save against melee attacks and a 5+ invulnerable save against ranged attacks.
