| Review | |||||||||
| - One of the few heroes who can grant Stun Immunity - Can also be a healer with her AoE Heal - Her damage increases at 6th Transcendence with Ignore Defense - Not suitable for rerolling with two single-target attacks - Stun Immunity is easily replaceable with Evan, who is available from the start | |||||||||
Physical Attack Buffer with Stun Immunity
One of the few characters with Stun Immunity. While Evan, who also has Stun Immunity, provides a Durability Boost, Sieg offers a Physical Attack Boost. He is recommended for content where firepower is more important than durability, such as Castle Rush.
Can Also Be Used as a Single-Target Physical Attacker
Sieg has two single-target physical skills and can be used as an attacker in content where single-target physical attacks are effective, like Castle Rush or Advent Expedition. Skill 2 also heals all allies while attacking, giving him healer-like qualities.
6 Transcendence and Skill 2 Enhancement are Useful
At 6 Transcendence, Skill 2 becomes an Ignore Defense attack, making Transcendence effective for improving his attacker performance. Additionally, enhancing Skill 2 increases the amount of healing, so prioritize Skill Enhancement if you want to boost his healing performance.

Best Build for Sieg
Recommended Equipment Sets
| Set | Reason for Recommendation |
|---|---|
Vanguard | - Increases HP recovery amount - Good compatibility with Physical Attack Boost passive - Recommended for Attacker/Supporter hybrid user |
Avenger | - Easy to increase damage output with Boss Damage Dealt Boost - Recommended for prioritizing Attacker performance |
Gatekeeper | - Compensates for low durability - Recommended for prioritizing durability or support performance |
Choose equipment based on whether you want Sieg to primarily play the role of an Attacker or a Supporter. Vanguard if prioritizing both, Avenger if prioritizing Attacker, Gatekeeper if prioritizing Support or Durability is recommended.
Vanguard Set (Balance Type)
| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Vanguard | [Weapon] - All Attack (%) - Crit Rate [Armor] - All Attack (%) - Block Rate | - All Attack (%) - Crit Rate - Crit Damage - Weakness Hit Chance - Block Rate |
In situations where you want to use him as Attacker/Supporter hybrid, increasing Attack with Vanguard is recommended. Equip Attack options if you want to increase healing, Crit Rate to increase damage, or Block Rate to increase durability.
Vanguard Set and Best CharactersAvenger Set (Damage Type)
| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Avenger | [Weapon] - Crit Rate - Crit Damage [Armor] - All Attack (%) | - Crit Rate - Crit Damage - Weakness Hit Chance - All Attack (%) |
In situations where you want to use him as a Single-Target Physical Attacker in Boss Content, focusing on Crit Rate with Avenger is recommended. Adopting Block Rate is an option if durability is lacking, but basically focus on offensive options.
Avenger Set and Best CharactersGatekeeper Set (Durability Type)
| Set | Main Stat Candidates | Substat Candidates |
|---|---|---|
Gatekeeper | [Weapon] - All Attack (%) - Crit Rate (%) [Armor] - Block Rate - All Attack (%) | - Crit Rate (%) - Crit Damage - All Attack (%) - Weakness Hit Chance - Block Rate |
Since his original durability is not very high, adopting Gatekeeper to make him harder to defeat is also an option. Think of it as compensating for weaknesses rather than specializing in durability, and prioritizing Attack-oriented options is fine.
