Understand Festering Desire
Useful when…
- Improving a damage-dealing Elemental Skill’s damage and chance to critically hit.
- Adding Energy Recharge while using a sword user whose Skill is important to their damage.
What does it improve?
At refinement 1, Festering Desire increases Elemental Skill DMG by 16% and Elemental Skill CRIT Rate by 6%; refinement 5 raises those values to 32% and 12%. These Skill-specific bonuses do not state improvements to normal or charged attacks, Burst damage, or the character’s general CRIT Rate. Its secondary stat is Energy Recharge, which supports energy needs but is separate from the Skill damage effect.
When does it fit a sword user?
The clearest fit is a sword character whose Elemental Skill deals a substantial share of their damage and whose Burst benefits from Energy Recharge. The passive does not require a trigger or field-time condition in the supplied description, so the listed Skill bonuses are not limited to hitting an opponent after a particular action. Compare the character’s actual damage sources before choosing it: a character whose Skill is mainly utility may use little of the weapon’s distinctive damage bonus.
Which upgrades are sensible?
Ascension increases the weapon through stages; the listed steps use Dandelion Gladiator materials, horns, and Recruit’s Insignia at the first example. Refinement improves both Skill bonuses, and its progression uses Festering Dragon Marrow rather than another weapon copy. The examples show one marrow and 1,000 Mora for refinement 1 to 2, and one marrow with 8,000 Mora for 4 to 5. Refinement is most relevant when the wielder regularly deals Skill damage; ascension is the more direct general weapon progression.
How do the alternatives differ?
Absolution gives CRIT DMG and increases the wielder’s DMG when the value of a Bond of Life is increased, so its stated condition differs from Festering Desire’s Skill-specific bonuses. Amenoma Kageuchi instead grants seeds after Elemental Skills and converts them into Energy after a Burst; it is an energy-return option with an explicit Skill-to-Burst sequence. Aquila Favonia has ATK and Physical DMG Bonus, plus an effect triggered by taking damage. These are comparisons of distinct effects, not automatic upgrades or equivalents.
Limitations and tradeoffs
- Its damage bonuses apply specifically to Elemental Skills, not all damage.
- Energy Recharge may be less useful if the wielder does not need help meeting Burst energy requirements.
- Refinement improves a focused passive, so its value depends on the character’s Skill damage contribution.
Common mistakes to avoid
- Counting the Skill CRIT Rate as a general CRIT Rate bonus for normal attacks or Bursts.
- Choosing it for Energy Recharge alone without checking whether the character needs that stat.
- Assuming Amenoma Kageuchi’s Energy return or Aquila Favonia’s damage-taken trigger works like Festering Desire’s passive.
