What are the best artifact sets for Thoma in Genshin Impact?

Thoma is a 4-star Pyro character in Genshin Impact who primarily serves as a support and shield provider. His kit revolves around his Elemental Skill, which generates a shield, and his Elemental Burst, which deals Pyro damage and provides additional shielding. To maximize Thoma's potential, it is important to focus on artifact sets and stats that enhance his shielding capabilities, energy recharge, and support utility. Here is a detailed guide on how to build Thoma effectively.

First, let's discuss the mechanics of Thoma's abilities. His Elemental Skill, Blazing Blessing, creates a shield that scales off his maximum HP. This shield not only absorbs damage but also applies Pyro to nearby enemies when it is first activated. His Elemental Burst, Crimson Ooyoroi, deals AoE Pyro damage and creates a Fiery Collapse effect, which deals additional Pyro damage and refreshes his shield. The shield's strength and uptime are crucial for Thoma's role as a support, so building him with high HP and energy recharge is essential.

For artifact sets, the best options for Thoma are those that enhance his shielding and support capabilities. The 4-piece Noblesse Oblige set is a strong choice, as it increases his Elemental Burst damage and provides a team-wide attack buff after using his Burst. This set synergizes well with Thoma's role as a support, as it allows him to boost the damage output of his teammates. Another excellent option is the 4-piece Tenacity of the Millelith set, which increases his HP and provides an attack buff to the team when his Elemental Skill hits an enemy. This set further enhances his shielding and support utility.

If you are unable to obtain a full 4-piece set, you can mix and match 2-piece sets that provide HP and energy recharge bonuses. For example, combining a 2-piece Tenacity of the Millelith set with a 2-piece Emblem of Severed Fate set can be effective. The Tenacity set increases his HP, while the Emblem set boosts his energy recharge, ensuring that he can use his Elemental Burst more frequently.

When it comes to artifact main stats, prioritize HP on the Sands, Goblet, and Circlet. This will maximize the strength of his shield. For substats, focus on HP percentage, energy recharge, and flat HP. Energy recharge is particularly important, as it allows Thoma to use his Elemental Burst more often, maintaining shield uptime and providing consistent support.

For weapons, Thoma benefits from polearms that provide energy recharge or HP. The Favonius Lance is an excellent choice, as it provides energy recharge and generates energy particles for the team. The Black Tassel is another good option, as it increases his HP, further boosting his shield strength. If you have access to 5-star weapons, the Staff of Homa is ideal, as it provides both HP and critical damage, enhancing Thoma's overall utility.

In terms of team composition, Thoma works well in teams that benefit from his shielding and Pyro application. He is particularly effective in teams that rely on reactions like Vaporize or Melt. For example, pairing Thoma with a Hydro DPS like Tartaglia or Ayato can create powerful Vaporize reactions. He also synergizes well with characters who benefit from consistent Pyro application, such as Ganyu for Melt reactions. Additionally, Thoma can be a valuable support in teams that require a strong shield, such as those featuring fragile DPS characters like Yoimiya or Hu Tao.

When building Thoma, it is important to avoid common mistakes such as neglecting energy recharge or focusing too much on damage stats. While Thoma can deal some damage, his primary role is to provide shields and support, so prioritizing HP and energy recharge is crucial. Additionally, make sure to level up his talents, particularly his Elemental Skill and Burst, as this will significantly enhance his shielding and support capabilities.

Advanced techniques for optimizing Thoma include managing his energy recharge to ensure consistent shield uptime and timing his Elemental Skill and Burst to maximize their effectiveness. For example, using his Elemental Skill immediately before his Burst can help ensure that his shield is active when the Fiery Collapse effect triggers. Additionally, positioning Thoma strategically to apply Pyro to multiple enemies can enhance his utility in combat.

In summary, building Thoma effectively involves focusing on artifact sets and stats that enhance his shielding and support capabilities. Prioritize HP and energy recharge, and choose artifact sets like Noblesse Oblige or Tenacity of the Millelith to maximize his utility. Pair him with characters who benefit from his shielding and Pyro application, and avoid common mistakes like neglecting energy recharge or focusing too much on damage stats. By following these strategies, you can build a Thoma that excels in providing support and protection for your team.
