Medium humanoid (human, shapechanger), neutral evil
Skills Perception +2
Shapechanger. The wereboar can use its action to polymorph into a boar-humanoid hybrid or into a boar, or back into its true form, which is humanoid. Its statistics, other than its AC, are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.
Charge (Boar or Hybrid Form Only). If the wereboar moves at least 15 feet straight toward a target and then hits it with its tusks on the same turn, the target takes an extra 7 (2d6) slashing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone.
Multiattack (Humanoid or Hybrid Form Only). The wereboar makes two attacks, only one of which can be with its tusks.
Maul (Humanoid or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage.
Tusks (Boar or Hybrid Form Only). Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) slashing damage. If the target is a humanoid, it must succeed on a DC 12 Constitution saving throw or be cursed with wereboar lycanthropy.
Wereboars are ill-tempered and vulgar brutes. As humanoids, they are stocky and muscular, with short, stiff hair. In their humanoid and hybrid forms, they use heavy weapons, while in hybrid or animal form, they gain a devastating goring attack through which their curse is spread. A wereboar infects other creatures indiscriminately, relishing the fact that the more its victims resist the curse, the more savage and bestial they become.
Characters as Wereboars
The character gains a Strength of 17 if his or her score isn't already higher, and a +1 bonus to AC while in boar or hybrid form (from natural armor). Attack and damage rolls for the tusks are based on Strength. For the Charge trait, the DC is 8 + the character's proficiency bonus + Strength modifier.
