Sword of Unending Winter

A fey longsword covered in frost which, when wiped away, reveals a clear blade made out of solid ice. The blade does not seem to melt at even the highest of temperatures. It feels extremely cold to the touch and prolonged contact causes frostbite.

The blade freezes everything it touches. When put in water, it will turn water within a radius of 5 feet into solid ice. The blade is sharp enough to be pulled out of this ice assuming the hilt can still be pulled.

Attacks made with this weapon deal an additional 1d8 cold damage. A creature reduced to 0HP by this sword is frozen solid.

Hit points lost to this weapon cannot be healed at a temperature below 21°C/70°F.

An eladrin attuned to this sword becomes aligned to winter and cannot change season.

The sword has 10 charges. It regains 1 for each hour it spends submerged up to its hilt in moonlit ice. 1 charge - Ray of Frost 3 charges - Slow, Snillocs Snowball Swarm 6 charges - Cone of Cold
