Duskblade is an enchanted halberd +2. It has the same properties as a Halberd +2 as well with 1d10 +2 points of piercing damage, 7 speed factor +2 THACO bonus and a weight of 12 lbs, but it inflicts +2 points of cold damage when hitting an enemy, which also raises the value of the item. This item appears in Baldur's Gate II: Shadows of Amn and this item will probably appear in Baldur's Gate II: Enhanced Edition.
This weapon is dropped by Shade Patrick during the battle between the Shade Lord at the Ruined Temple area during the subquest to stop the murders in Umar Hills.
In-game description
| “ | Halberd +2 Duskblade
Though once a simple halberd, this weapon spent many hundreds of years in a tomb next to the soul phylactery of a powerful lich. The creature was eventually erased from existence, purportedly by another of its kind, but such close proximity to that concentrated evil has imbued this blade with the very essence of night and the chill of darkness, energy that becomes deadly in combat. It is a foul weapon, and a warrior should use it with caution. |
