Alpha Dire Werebear

Shapechanger. The werebear can use its bonus action to polymorph into a Large bear-humanoid hybrid or into a Huge bear, or back into its true form, which is humanoid. Its statistics, other than its size and AC, are the same in every form. The equipment it is wearing or carrying isn't transformed and may break or fall off. It reverts to its true form if it dies.

Legendary Resistance (3/Day). If the werebear fails a saving throw, they can choose to succeed instead.

Siege Monster. The werebear deals double damage to objects and structures.

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

Pack Leader. As the Alpha, the dire werebear provides unnerving leadership to its pack. Allies to the dire werebear within 60 feet are granted with immunity to the frightened and charmed conditions.

Multiattack. In bear form, the werebear makes three claw attacks and one bite. In humanoid form, it makes three greatscythe attacks. In hybrid form, it can attack like a bear or a humanoid.

Bite (Bear or Hybrid Form Only). Melee Weapon Attack: +13 to hit, reach 5 ft., one target. Hit: 23 (3d10 + 7) piercing damage. If the target is a humanoid, it must succeed on a DC 19 Constitution saving throw or be cursed with werebear lycanthropy.

Feral Beast. The werebear can make up to three reactions each round if it is lower than half its maximum hit points.

Daunting Strike. When the werebear is hit with an attack roll it may use a reaction to make one claw or greatscythe attack to it's attacker.

Legendary Tenacity. If the werebear is hit with an attack roll and can see the attacker, they can use their reaction to roll a d6. On 1-5 you halve the damage, on a 6 the damage is negated instead. Additionally, if they were to be reduced to 0 hit points it becomes 1 instead.

The dire werebear can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature's turn. The werebear regains spent legendary actions at the start of its turn.

Charged Maul Attack. The werebear can move up to half its movement speed and makes one claw or greatscythe attack.

Grizzly Gore (Costs 2 Actions). The werebear moves at least 10 to 40 feet to its target and makes one bite attack, then heals equal to the damage given.

Roar of Ferocity (Costs 3 Actions). The werebear let's out a bellowing roar that can be heard up to 5 miles. Every creature that can hear within 120 feet that is not allied with the werebear must make a DC 17 Wisdom saving throw or be frightened for one minute. If the save is made, then the creature is immune to this effect for 24 hours. Additionally, every friendly creature the werebear selects gains a d8 to all damage rolls for one minute. The werebear may also receive temporary hit points equal to 15 times the number of creatures selected (up to a maximum of 5 creatures). This effect will only work once per battle.
