|---|---|

Duessel Best IVs
Recommended IVs
| Stat | Superboon/Superbane | IV Recommendation |
|---|---|---|
| HP (19) |
|
★★☆☆☆ |
| Atk (25) |
|
★★★★★ |
| Spd (5) |
|
★☆☆☆☆ |
| Def (12) |
|
★★★★☆ |
| Res (7) |
|
★★★☆☆ |
◯ = Stat gains +4 with a superboon, ✕= Stat goes down by -4 with a superbane, - = No assets or flaws
| See the IV Checker for All Units | Trait Fruits—How to Change IVs |
When using an Ascendant Floret, we recommend getting the next superboon if it fits the hero. If not, consider what stat your hero needs most.
+Atk/-Spd
The best IVs for Duessel are+Atk and -Spd. A +Atk IV will effectively raise this units' ability to deal damage. His Spd is not important as it is very unreliable. Additionally, Obsidian Lance can guarantee him follow-up attacks so forcing Spd into his kit is not needed at all. With all that said, Spd is the ideal bane for Duessel.
+Atk for a +10 Merge
We recommend a +Atk IV when merging Duessel to 10. His Atk levels combined with the guaranteed follow-up attack from Obsidian Lance that is quite easy to trigger, will allow him to attain a decent level of offensive prowess.
If you prefer a full on tank Duessel, you can also go for +Res or +Def stats depending on your needs.

Duessel Best Weapon Refine
Effect of Duessel's Refined Weapon
| Exclusive Weapon Effect from Refining (Special Effect Type) | |
|---|---|
| SP: 400 | |
| Might: 16 Range: 1 HP: 3 Grants Def+3. Enables 【Canto (2)】. At start of combat, if foe's HP ≥ 75% or if number of allies adjacent to unit ≤ 1, inflicts Atk/Def-6 on foe, unit makes a guaranteed follow-up attack, and reduces damage from foe's attacks by 20% of unit's Def during combat (excluding area-of-effect Specials). For foes within 3 rows or 3 columns centered on unit, inflicts Atk/Def-5, neutralizes bonuses to Atk/Def, neutralizes effects that grant "Special cooldown charge +X", and those foes cannot make a follow-up attack during combat. At start of combat, if unit's HP ≥ 25%, inflicts Atk/Def-6 on foe and deals damage = 20% of unit's Def during combat (excluding area-of-effect Specials), and restores 7 HP to unit after combat.  ：500  ：200 |
|
We recommend the Special Effect Refine for Obsidian Lance
Refined Obsidian Lance grants 【Canto (2)】 inflicts Atk/Def-12 onto Duessel's foe and grants Duessel a guaranteed follow-up attack, true damage and true damage reduction equal to 20% of Duessel's Def, and 7 HP post-combat healing.
Refined Obsidian Lance also inflicts Atk/Def-5, dull Atk/Def bonuses, a Guard effect, and follow-up denial to all foes within 3 rows or 3 columns centered on Duessel. This effect is active even during ally's combats, giving Duessel a useful support effect outside combat.
This weapon refine improves Duessel's support and combat abilities. However, the combat abilities are reliant on Duessel's foe having high HP or Duessel having only one or no nearby allies.

Duessel Roles, Strengths, and Weaknesses
Duessel Roles
Duessel is a close physical attacker (range = 1). Therefore, when not accounting for the Weapon Triangle, the amount of damage he deals will be equivalent to his Atk minus the foe's Def stat.
Duessel Strengths
Refined Obsidian Lance has offense, defense, and support at the same time
Refined Obsidian Lance grants 【Canto (2)】 inflicts Atk/Def-12 onto Duessel's foe and grants Duessel a guaranteed follow-up attack, true damage and true damage reduction equal to 20% of Duessel's Def, and 7 HP post-combat healing.
Refined Obsidian Lance also inflicts Atk/Def-5, dull Atk/Def bonuses, a Guard effect, and follow-up denial to all foes within 3 rows or 3 columns centered on Duessel. This effect is active even during ally's combats, giving Duessel a useful support effect outside combat.
This weapon refine improves Duessel's support and combat abilities. However, the combat abilities are reliant on Duessel's foe having high HP or Duessel having only one or no nearby allies.
Duessel Weaknesses
Weak with poor positioning
Remember the benefits of having no adjacent allies! Duessel is a totally different unit when all of his skills are activated. This makes him quite tricky to use in maps that are in closed corridors such as Urusla's Grand Hero Battle map shown below:
You can easily trigger Obsidian Lance and Def/Res Solo 4 when initiating as they check Duessel's position in relation to allies upon enterting combat, but be wary that Rouse Def/Res 3 checks for allies at the beginning of the turn! Make sure be mindful of Duessel's positioning when ending your turn.
Weak to Cavalry Effective Weapons
Duessel takes 1.5x damage from cavalry-effective weapons like Ridersbane, and one blow from this type of weapon is sure to take him down. Make sure you know what weapons you are up against before hopping too far into the line of battle!

Inheriting Lull Atk/Def 3 or Def/Res Solo 4
Duessel can be used to inherit the skills Lull Atk/Def 3 or Def/Res Solo 4. If you are able to inherit Def/Res Solo 3 from another unit, you can inherit both Def/Res Solo 4 and Lull Atk/Def 3 from Duessel. However, Duessel is powerful and very reliable unit. Please think carefully before fodderring him off!
