Pack Tactics. The lion has advantage on an attack roll against a creature if at least one of the lion's allies is within 1 square of the target and the ally doesn't have the incapacitated condition.
Rend. Melee Weapon Attack: +8 to hit, reach 2 sq., one target. Hit: 15 ( 2d8+6 ) piercing damage. If the lion moved at least 4 square straight toward the target immediately before the hit, the target must succeed on a DC 16 Strength saving throw or have the prone condition. If the target has the prone condition, the lion can make another Rend attack against it as a bonus action.
When it comes to infiltrating giant steadings, I must admit that spotted lions are in some ways preferable to, say, dire wolves or cave bears. Namely, if they're well fed, they're more likely to stretch and yawn than they are to raise an alarm when they spot you.Roughly twice the size of a common lion, a spotted lion has a dusky coat and mane, both speckled with charcoal-colored spots. Spotted lions gather in prides to hunt enormous prey ranging from giant elk to mammoths. Stone and cloud giants often keep these massive beasts as pets and hunting companions.
