Recomended Characters
| Character | Explanation |
|---|---|
Psyche | - Excresduo provides Psyche with the Skill DMG boost that Elpides Abound is lacking. Since ideal demon wedges for her Consonance Weapon focus more on landing crits, the additional Skill DMG provided by this weapon is almost essential. |
Lynn | - When Supports are providing enough Sanity upkeep, Lynn can consider using the Excresduo for a large Skill DMG boost. However, for a more consistent Lynn, you will typically want to equip Bluecurrent Pulse over this weapon. |
Lisbell | - Lisbell will greatly benefit from the Excresduo's increase in Skill DMG as it will apply to her consonance weapon. |
Similar to Wanewraith, Excresduo provides the user with an unconditional Skill DMG increase. This means it's useful on any character that wants to focus on dealing DMG, especially those who are being built around Skill DMG.
