Special Traits

  • Shapechanger. The oreios giant can use its action to polymorph into a Huge 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 each form. Any equipment it is wearing or carrying isn’t transformed. It reverts to its true form if it dies.
  • Keen Smell. The oreios giant has advantage on Wisdom (Perception) checks that rely on smell.


  • Multiattack. In bear form, the oreios giant makes two claw attacks. In humanoid form, it makes two greataxe attacks. In hybrid form, it can attack like a bear or a humanoid.
  • Claw (Bear or Hybrid Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 18 (3d8 + 5) slashing damage.
  • Greataxe (Humanoid or Hybrid Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 18 (3d8+ 5) slashing damage.
  • Bite (Bear or Hybrid Form Only). Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 21 (3d10 + 5) piercing damage.


This massive humanoid is hairier than usual, even for a giant of its size. It has thick eyebrows and a squat nose, with black, beady eyes.

Polyphonte was the granddaughter of Ares, who scorned womanhood and preferred to hunt like Artemis. Infuriated by Polyphonte’s behavior, Aphrodite decided to punish her by forcing the mortal to fall in love with a bear. The results of their union are the oreios.

Oreios giants look much like normal giants, though slightly stockier, and with coarser, stiffer hair and stiff. In their hybrid forms they are terrifying foes, wielding their axes and bite to good effect.

Sacred to Ares. The original giants were spawned through an argument with two different gods, Aphrodite and Artemis. Polyphonte scored Aphrodite’s worship and went to the mountains to practice Artemis’ sports instead.

This displeased Aphrodite, who made Polyphonte fall in love with a bear. Disgusted, Artemis turned all beasts against the mortal. Polyphonte fled to her father’s house and raised the half-bear children, who honored neither god nor man. Zeus sent Hermes to punish them as he saw fit, but they were ultimately Ares’ kin and so he rescued them before Hermes could chop off their hands and feet.

Oreios giants anger quickly. They usually begin a battle in giant form, then switch to hybrid form to take advantage of their immense strength in that shape.
