Keen Smell. The tiger has advantage on Wisdom (Perception) checks that rely on smell.
Pounce. If the 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 13 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.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (1d10 + 3) piercing damage.
Claw. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage.
Teleport (Recharge 4–6). The tiger magically teleports, along with any equipment it is wearing or carrying, up to 40 feet to an unoccupied space it can see. Before or after teleporting, the tiger can make one bite or claw attack.
Chameleon Power. As a free action, the tiger can magically blend in with the surroundings. This provides a +10 competence bonus on his stealth check. Being hit, attacking, or moving more than half his speed breaks the effect. Attacking coming out of stealth next to the target, on a failed perception check by the target, grants the tiger advantage on next attack roll.
