Keen Smell. The tiger has advantage on Wisdom (Perception) checks that rely on smell.

Pounce. If Xenev Tiger moves at least 20 feet straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 16 Strength saving throw or be knocked prone. If the target is prone, the tiger can make one bite attack against it as a bonus action.

Two attacks each turn - One bite and one Claw

Guardian Lunge. If an ally within 15ft is hit with a melee attack, Xenev Tiger may use it's reaction to lunge 15ft and make a Claw attack on the attacker
