Dagger of the North
Each dagger is just slightly different from the rest but are obviously made from the same blacksmith. The pommel and hilt are a brushed steel, and where the blade, hilt and guard meet, each has a small sapphire embedded in the metal. A faint sense of cold air is felt near the weapon when it’s drawn from it’s sheath and a light frost or fog will linger in the air around the steel blade.
(+1 dagger, Roll of 20 does an additional +2 cold damage to target)
