| Review | |||||||||
| - A debuffer and Physical attacker - His excellent passive causes Defense Reduction for All Enemies - Tenacious with Guts + Barrier creation when Guts is active - Increases damage output with Physical Attack Boost at 6th Transcendence | |||||||||
Highly Versatile Debuffer
His debuffs, including Defense Reduction for all enemies, Physical Vulnerability, Incoming Healing Reduction, and Reduce Buff Duration, are highly effective. He performs best in a Physical team, though he can also be valuable in other team compositions.
Effective in Any Content
There's no content where he isn't effective; as a debuffer, he can contribute in any battle. It's best to switch between Vanessa, who applies Magic Vulnerability, and Ace, who applies Physical Vulnerability, depending on the situation.

Best Build for Ace
Recommended Equipment Sets
| Set | Reason |
|---|---|
Gatekeeper | - Increases durability to support allies for extended periods |
Ace's passive skills, particularly Defense Reduction and Healing Reduction, are exceptionally powerful. Since you want Ace to stay on the field as long as possible, the Gatekeeper set is highly recommended for boosting durability.
Gatekeeper Set
| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Gatekeeper | [Weapon] - HP (%) - Defense (%) [Armor] - Block Rate - Damage Reduction | - Speed - Block Rate - HP (%) - Defense (%) - All Attack (%) |
Use the Gatekeeper set to increase durability with stats like HP and Block Rate. If you want to boost the shield value when Authority activates, adding All Attack (%) substats is also a viable option.
