Canopy Camouflage. The rosemar has advantage on Dexterity(stealth) checks made in forest or jungle environments.

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

Speak with Plants. The rosemar can communicate with plants as if they shared a language.

Sun Bathe. If the rosemar is under direct sunlight it recovers 2 hit points at the start of each of its turns.

Multiattack. The rosemar makes two vine whip attacks.

Vine Whip. Melee Weapon Attack: +5 to hit, reach 10 ft., one target. Hit: 8 (2d4 + 3) piercing damage. If the target is a medium or smaller creature, the roseamar can attempt to grapple it. The target must succeed a DC 13 Strength (athletics) or Dexterity (acrobatics) check or become grappled. Until this grapple ends, the target is restrained, and the rosemar can't attack another target with its vine whip.

Rage Powder (Recharge 5-6). A cloud of pollen bursts from the rosemar's petals. Each creature within 5 ft of it must make a DC 13 Constitution saving throw or become blinded by rage. An affected creature will use every attack they have against the closest living target to them. An affected creature can remake their saving throw at the end of each of their turns.

Sun's Ray (Recharge 6). A beam of brilliant light flashes out from the rosemar's head in a 5-foot-wide, 60-foot-long line. Each creature in the line must make a DC 13 Constitution saving throw. On a failed save, a creature takes 6d6 radiant damage and is blinded until the rosemar's next turn. On a successful save, it takes half as much damage and isn't blinded by this attack. Undead and oozes have disadvantage on this saving throw.

Take Root. This creature resists any effects that would have it move unwillingly.
