Slow-active Venom (Passive) Any model that suffers a Wound from a Rhûnish War Drake, but is not slain, reduces their Fight value and Attacks by 1 (to a minimum of 1) for the remainder of the game. Once an enemy model has been affected by this special rule, it cannot be affected again for the remainder of the game, even if wounded by a different Rhûnish War Drake.
Terror (Passive) Should a model wish to Charge this model, it must first take a Courage test before it moves. If the test is passed, the model may Charge as normal. If the test is failed, the model does not Charge and may not move at all this turn.
Sometimes, a model will only cause Terror in certain enemies. In these instances, the creatures that are affected are clearly listed, and only those models need to make a Courage test before charging this model. For example, a model with the Terror (Orc) will cause Terrior in all Orc models.
