Bijan summons a sand beast and rides it forward for 12 seconds, gradually gaining speed. When it hits an obstacle or enemy hero, or reaches the end of its duration, the beast dives underground, dealing 300 (+120% AD) physical damage, knocking enemies up for 1 second, and reducing their armor by 15% for 4 seconds. While charging, Bijan is immune to control effects and may dismount at any time; the beast continues in the same direction before diving underground. A nearby ally can mount the beast and continue using skills and normal attacks. The ally is forced to dismount if controlled, if they use a movement skill, or if Bijan dismounts first. If the diving beast hits an enemy, Bijan immediately gains 5 stacks of his passive buff.
