Lightning reflexes. The kamana has advantage on all dexterity checks.
Multiattack. The kamana makes 2 claw attacks. Claw. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) piercing damage. Lightning Bolt (Recharge 5 or 6). A bolt of lightning comes from the kamana in a 30 ft. straight line. Every creature within that line must make a dexterity saving throw DC 15 or take 3d6 lightning damage.
Thunderflee (recharge 5 or 6). When the kamana gets hit with an attack, it teleports itself to an unoccupied space it can see within 60 ft. Immediately after it disappears, a thunderous boom sounds, and each creature within 10 feet of the space it left must make a Constitution saving throw DC 15, taking 3d6 thunder damage on a failed save, or half as much damage on a successful one.
