The blink dog is not a fearsome fighter, though they are as intelligent as many a human and know well enough how to use their abilities to advantage. Because of their magic resistance, they rarely fear spellcasters ... while their natural ability to blink, similar to the 3rd level mage spell. This ability is done without limitation. Typically an entire blink dog pack will blink in waves of 3 to 5 animals, with others standing their ground to draw attackers who can then be attacked in turn from the rear by blinking dogs. As the dogs are intelligent, they have grown effective in this strategy.
Likewise, an entire pack, if seriously challenged, will disappear all at once, as they have the ability to blink to the Astral Plane and remain there (unlike the mage spell). However, blink dogs do not like to attack aggressively. They will prefer to weaken and injure opponents; then blink to a distance of four combat hexes and cease attacking, to give the enemy a chance to back away. Blink dogs will not attack an opponent that makes it clear they are unarmed.
Blink dogs can be understood through the spell or ability, speak with animals.
