Lengthens

From GuildWiki

A weapon upgrade, weapon modifier or armor piece that "lengthens" the duration of a condition or skill will typically increase the duration by 33%.

[edit] Notes

• This applies not only to conditions inflicted by the weapon that bears the weapon upgrade itself, but also conditions of the same type inflicted by skills. For example: A Necromancer wielding a barbed weapon can lengthen the foes' bleeding caused by the popular Signet of Agony + Plague Sending combo. Likewise, an Elementalist wielding a heavy weapon can lengthen the weakness caused by Enervating Charge.
• Indirect condition application is not always effected by a Lengthens Prefix. See below for examples:
  • Withering Aura: Heavy Weapon upgrade will only Lengthen Weakness if the attacker has the mod. The caster having the mod makes no difference.
