Noctenium

Noctenium skill improving consumable.

Noctenium Infusions are given as quest rewards from some Vanguard Requests. Infusions can be activated in inventory and they give buffs to skills used.

Buffs include damage increase, but also stun attacks and priest blessings duration, faster resurrect, faster Rain of Arrows, and giving warrior Poison Blade 1 extra edge point.

Noctenium Infusions have some problems, including so called "noctenium lag". Game client actually sends character's inventory to server every time infusion is spent and server sends it back. Other problem is that classes with fast attack speed like warrior use much more noctenium than classes with slower but harder-hitting attacks like slayer.

Nowadays it's recommended to use Noctenium Refiners from Vanguard Initiative merchants that combine certain amount of Noctenium Infusions to a time-limited buff.

Lore
Lore concerning noctenium is closely tied to Alliance system. There was quest Noctenium Knowledge along with its single-player dungeon on Island of Dawn about noctenium before Alliance was removed from game.

Noctenium initially came from Alliance quests, which gave Pure Noctenium Powder as reward. This had to be combined with Noctenium Tissue dropped from monsters on Alliance territories using Affinity Catalyst from Alliance merchant. Affinity Catalyst is still available on special merchant after Alliance removal. This gave certain amount of Noctenium Infusions. Activating Noctenium also had effect of improving PVP attack and defense (now removed effect).

As Noctenium Infusions are now rewards from Vanguard Requests, there is no longer need to craft them.
