Actions

Multiattack.The frostmourn makes one Freezing Touch attack and one Icy Axe attack. It can replace one of these attacks with a Polar Ray attack.

Freezing Touch.mw 10 to hit, reach 5 ft., one creature. ({@damage 4d8) cold damage plus 18 (4d8) necrotic damage. If this damage would reduce the target to 0 hit points, the target drops to 1 hit point instead and has the petrified condition, turning into a frozen statue. If the statue takes bludgeoning damage, it shatters, killing the frozen creature. If the statue would take fire damage, it instead takes no damage and thaws, ending the petrification.

Icy Axe.mw 10 to hit, reach 10 ft., one target. ({@damage 3d8 + 6) slashing damage plus 7 (2d6) cold damage.

Polar Ray.rs 8 to hit, range 120 ft., one target. ({@damage 5d10 + 4) cold damage, and the target's speed is reduced by 10 feet until the end of its next turn.

Reactions.Reactions the creature can take:

Blizzard Escape.Immediately after a creature the frostmourn can see hits it with an attack roll, the frostmourn momentarily dissolves into a blizzard, reducing the damage to itself by half. The frostmourn can then magically teleport to an unoccupied space it can see within 30 feet of itself.

Frostmourn

When a frost giant is murdered in a dishonorable manner—perhaps poisoned, stabbed in the back, or killed while sleeping—the slain giant can rise as a frostmourn. Driven by its desire for vengeance, the frostmourn can turn the living into frozen statues with a touch or blast enemies with frigid wind. Achieving vengeance is not always enough to grant these creatures rest; often, their hatred and loathing of the living is sufficient to keep them roaming the wilds for years after their murderers are slain.

A frostmourn looks like a desiccated corpse mummified by exposure to bitter cold. It carries the marks of its death on its body: a wound that seeps frosty vapor or vibrant, purple veins showing the ravages of poison. It can momentarily dissolve its body into a swirling blizzard to avoid harm, reforming at a distance to continue its assault.
