FYI bears are awesome

RUST BEAR

# Encountered: 1 (1d4)
Alignment: Neutral
Movement: 120' (40')
AC: 6
HD: 5
Attacks: 2 claws, bite
Damage: d4/d4/d6
Save as: Fighter 2
Morale: 8
Hoard Class: VI

These enchanted animals appear to be grizzly bears with a coppery metallic sheen to their fur. Contact with a rust bear has the same effect as a rust monster, but these creatures do not hunger for or consume metals. If a rust bear hits a single target with both claw attacks it automatically hugs the victim for an additional 2d8 damage and any metallic armor worn is automatically rusted, no matter how powerful the enchantment.

PHASE BEAR

# Encountered: 1 (1d2)
Alignment: Neutral
Movement: 120' (40')
AC: 6
HD: 6
Attacks: 2 claws, bite
Damage: d4/d4/d6
Save as: Fighter 4
Morale: 8
Hoard Class: VI

Appearing as eerily translucent polar bears, all opponents of the phase bear are at -2 to hit due to its magical displacement abilities. Furthermore, the first strike against a phase bear always misses unless the attacker has access to true seeing magics. If a phase bear hits a single target with both claw attacks it automatically hugs the victim for an additional 2d8 damage, but this gives away the true position of the creature, negating the -2 to-hit penalty until the phase bear's next action.

WAR BEAST

# Encountered: 1d2 (1d2)
Alignment: Chaotic
Movement: 120' (40')
AC: 0
HD: 7
Attacks: 2 buzzsaws, bite
Damage: d12/d12/d8
Save as: Fighter 7
Morale: 10
Hoard Class: XVIII

Servants of the sword-god Nenguzei, these bipedal demon-bears have plating similar to the bulette and giant spinning buzzsaws instead of forepaws. If a war beast hits a single target with both saw attacks it automatically hugs the victim for an additional 2d20 damage. Any creature of less than 3 hit dice must save versus fear or flee in terror from these maniacal rampaging cyber-ursines.
