Ulfrun's Endurance

Voruna Ulfrun's Descent augment

Released Jul 27, 2023

Ulfrun's Endurance returns Voruna's charges when enemies die from Slash Status during Ulfrun's attack, within a rank-dependent radius. Consider it for sustained use of Ulfrun's Descent when Slash Status kills occur near Voruna.

Understand Ulfrun's Endurance

Useful when…

  • Voruna builds using Ulfrun's Descent that can secure Slash Status kills during its attack.
  • Situations where increasing the distance for charge restoration is valuable.

Trigger and radius

The augment restores Voruna's charges when an enemy dies from Slash Status within range during Ulfrun's attack. Its radius scales with rank: 5 m at rank 0, 15 m at rank 2, and 20 m at rank 3. Both the Slash Status kill and the timing during Ulfrun's attack are part of the trigger.

Build fit and investment

This is a standard Voruna mod with Zenurik polarity, base drain 6, and maximum rank 3. The listed rank-up steps cost 30, 60, and 120 Endo, plus 1,449, 2,898, and 5,796 Credits. Ranking increases the radius, which can make qualifying kills count from farther away; it does not change the stated kill and timing conditions.

Different Voruna augment effect

Prey of Dynar modifies Shroud of Dynar: it increases an enemy's Damage Vulnerability by 50%, and using Fang of Raksh on that enemy increases its spread radius by 150%. That is a separate ability effect and does not provide Ulfrun's charge restoration.

Limitations and tradeoffs

  • Charge restoration depends on an enemy dying from Slash Status during Ulfrun's attack and within the listed radius.
  • The mod consumes a standard slot and base drain 6.

Common mistakes to avoid

  • Expecting charge restoration from any kill rather than a Slash Status death during Ulfrun's attack.
  • Assuming the listed radius applies regardless of rank.
