Clockwork Lion

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

Pack Tactics. The clockwork lion has advantage on an attack roll against a creature if at least one of the lion’s allies is within 5 feet of the creature and the ally isn’t incapacitated.

Pounce. If the clockwork lion 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 clockwork lion can make one bite attack against it as a bonus action.

Running Leap. With a 10-foot running start, the clockwork lion can long jump up to 25 feet.

Mechanical Construct. Provided one has the correct tools and knowledge, one can fix the clockwork lion after it has been reduced to 0 hit points and bring it back to life. Depending on the skill of the mechanic, the lion may be friendly to the mechanic and its companions

Oil Slick. Twice per day, the clockwork lion can release a wave of slick oil. This counts as a cast of the spell grease.
