Boreal Displacer Beast

Avoidance. If the displacer beast is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the saving throw, and only half damage if it fails.

Boreal Reflection. The Boreal Displacer Beast can create one reflection of itself using a bonus action. It can have up to three images at a time. The reflections appear in the same space than the beast. The reflections are a perfect copy of the beast except for some subtle iridescent effects. An investigation check DC 14 reveals which beasts are reflections and which one is the real one. The check is done with disadvantage during combat.

• The reflexions share the initiative of the Borealis Displacer Beast. They can move on their own but cannot attack or interact with any objects or the environment.
• Physical attacks pass through the reflections, scattering them. Other attacks or effects have no impact on the reflections.
• If a reflection is in attack range, the Boreal Displacer Beast has advantage on the attack roll against a target. To the target, it seems that both, reflection and beast, move in perfect synchronisation coming from different angles.
• As an action, the Boreal Displacer beast can scatter one of its reflection in a burst of iridescent light made of ethereal curtains. All creatures within 30ft with line of sight of the image must make a Wisdom saving throw DC 14. If they fail, they become incapacitated for the next minute. They can repeat the saving throw at the end of their turn.

Arctic Predator. The Boreal Displacer Beast has adapted to the Frozen Tundra. In an arctic environment, the Displacer Beast has :

• +2 to its AC which sets it to 15
• Advantage to Stealth and Survival checks

Multiattack. The Boreal Displacer Beast makes two attacks with its tentacles.

Tentacle. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 7 (1d6 + 4) bludgeoning damage plus 3 (1d6) piercing damage.
