Weapon Skill Points (WSP) are hidden points that are accumulated by using Weapon Skills and executing Skillchains with special weapons, which fall into three categories: The first type are the weapons involved in the Trial Weapon quests that are used to gain access to special Weapon Skills for each weapon class (generally available between skill levels 230 and 250, depending on the weapon). The second type are weapons with special effects that are unlocked by accumulating Weapon Skill Points and are obtainable through Kindred's Seal NM battles, also known as KSNMs. Finally, points must be obtained on the weapons that are dropped in Nyzul Isle in order to allow access to the Mythic Weapon Weapon Skills in the Unlocking a Myth series of quests.
