The beast has a number of hit dice equal to: 1d6 per trainer level

When the beast hits a creature of equal or smaller size with an opportunity attack, the creature's speed becomes 0 for the rest of the turn.

When the beast is successful with a grapple attempt, it can immediately make one attack against the creature.

When the beast takes the Attack action, its attacks target two creatures that are within 5ft of each other, and within 5ft of the beast. Make one attack roll, and apply the result to both targets.

The beast regains 5 hit points at the start of its turn if it has at least 1 hit point, and less than 1/2 of its maximum hit points.

Melee Weapon Attack:, reach 5 ft., one target. (1d6) + strength modifier piercing damage (Bite) or slashing damage (Claws)

It makes a Strength (Athletics) check contested by the target's Strength (Athletics) or Dexterity (Acrobatics) check (the target chooses the ability to use). If its win the contest, the target becomes grappled.

The beast attempts to restrain a target that it has grappled. It makes another grapple attempt against the grappled target. If its win the contest, the target becomes restrained so long as it is grappled.

1 Command Point

A brilliant green light emits from the beast in all directions. Any number of creatures of your choice within 15 feet of the beast regain 2d8 hit points.

2 Command Points

The beast may transform into an Aspect of Spring. A soft glow shimmers around the beast and seems to rejuvenate the plant life around it. The beast immediately regains 10 hit points. The transformation lasts for 10 minutes or until the beast chooses to revert to its normal form (no action required). The transformation ends early if the beast drops to 0 hit points. The beast may not use this ability again until it has finished a long rest.

The beast can make an attack of opportunity against a creature when it moves to within 5ft of the beast.

If a creature within 5ft of the beast drops to 0 hit points, the beast can willingly end its aspect early so that the creature drops to 1 hit point instead.
