Dark Weapon is a Hex in Dark Souls 2. To cast a Hex, you must use a staff/chime or Special Weapons that can cast Hex.
"Felkin the Outcast applied his art to transform Magic Weapon into a hex.
Adds dark damage to the types of damage the weapon already inflicts.
Those who choose the path of dark are admonished by all manner of sorcerer.
But that does not stop the curious from being drawn to this strangely alluring craft.
- Purchased from Felkin the Outcast for 2700 souls
- Buffs weapon by adding 50 dark damage then multiplying the total dark by 1.3X. Lasts roughly 90 seconds (~50 seconds at 16INT). Does around same damage as Resonant Weapon for 1 Attunement slot cost, longer duration and no soul cost.
- While this is arguably the best weapon buff for dark-infused weapons, it should be noted that resonant weapon does slightly more damage (.05, a negligable amount but more none the less) and should not be overlooked for a hexer that focuses on chime based spells.
