Persistence

Persistence is the older search name for the duration support now recorded as Prolonged Duration I. The source history places the rename in version 0.3.0. Keeping the alias helps identify older guides, but a current gem comparison should use the newer name rather than treating the two names as separate supports that can be stacked.

The support grants more Skill Effect Duration to supported skills with a relevant duration. Its cost and reservation multiplier is a separate tradeoff, and the attribute requirement is listed independently. Increasing duration is useful only when the supported effect's duration is the part of the setup you want to change. It does not by itself prove higher damage, a faster cast or a larger area. The gem has no recommended-support list because it is itself a support; compatibility starts with the active skill receiving it. Engrave the required tier from an Uncut Support Gem, rather than using an Uncut Skill Gem or an Uncut Spirit Gem. Spark and Withering Presence are useful comparison pages because their source cards describe duration-related behaviour, yet their active effects and resource costs differ. Check the current gem tags and support wording when translating a guide that still uses the Persistence name.

Engrave an Uncut Support Gem of the required tier. Skill or support socketed in the gem panel.
