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 creates 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 best artifact sets for Thoma. The most recommended set for Thoma is the 4-piece Emblem of Severed Fate. This set increases his Energy Recharge by 20% and boosts his Elemental Burst damage based on his Energy Recharge. Since Thoma's Elemental Burst is a key part of his kit, this set helps him maintain consistent uptime on his shield and Pyro application. Another good option is the 4-piece Noblesse Oblige, which increases his Elemental Burst damage by 20% and provides a 20% attack boost to the entire team after using his Burst. This set is particularly useful in teams that rely on attack buffs.

For main stats, prioritize Energy Recharge on the Sands, HP% on the Goblet, and HP% or Healing Bonus on the Circlet. Thoma's shield scales with his HP, so increasing his HP will make his shield stronger. Energy Recharge is crucial because it ensures that Thoma can use his Elemental Burst frequently, which is essential for maintaining his shield and providing consistent Pyro application. Sub-stats to look for include HP%, Energy Recharge, and Elemental Mastery.

When it comes to weapons, the best options for Thoma are those that provide Energy Recharge or HP. The Favonius Lance is an excellent choice because it provides Energy Recharge and generates energy particles when Thoma scores a critical hit. This helps him maintain his Elemental Burst uptime. Another good option is the Prototype Starglitter, which also provides Energy Recharge and increases Thoma's attack after using his Elemental Skill. If you have access to 5-star weapons, the Engulfing Lightning is a top-tier choice due to its high Energy Recharge and attack boost based on Energy Recharge.

In terms of team composition, Thoma works well in teams that benefit from consistent Pyro application and shielding. One effective team is a Vaporize team with characters like Childe or Xingqiu as the main DPS, Thoma as the shielder and Pyro applicator, and Bennett as the healer and attack buffer. Another strong team is a Melt team with Ganyu or Ayaka as the main DPS, Thoma as the shielder, and Diona or Rosaria as the Cryo support. Thoma's shield and Pyro application can also be useful in Overload teams with characters like Raiden Shogun or Fischl.

When building Thoma, it is important to avoid common mistakes such as neglecting his Energy Recharge or focusing too much on damage stats. Thoma's primary role is to provide shields and support, so prioritizing HP and Energy Recharge is more important than trying to maximize his damage output. Additionally, make sure to level up his Elemental Skill and Burst talents, as these are the core of his kit.

Advanced techniques for optimizing Thoma include timing his Elemental Skill and Burst to maximize shield uptime and Pyro application. For example, using his Elemental Skill right before his Burst can help ensure that his shield is active when his Burst starts dealing damage. Additionally, pairing Thoma with characters who can generate energy particles, such as Bennett or Fischl, can help him maintain his Energy Recharge and keep his Burst active.

In specific scenarios, such as the Spiral Abyss, Thoma's shielding and Pyro application can be invaluable. For example, in floors with high damage enemies, Thoma's shield can protect your team and allow your DPS characters to focus on dealing damage. In floors that require Pyro application, such as those with Cryo shields, Thoma's consistent Pyro damage can help break shields quickly.

In conclusion, building Thoma effectively requires focusing on artifact sets and stats that enhance his shielding and energy recharge. The 4-piece Emblem of Severed Fate and 4-piece Noblesse Oblige are the best artifact sets for him, with main stats prioritizing HP% and Energy Recharge. Weapons like the Favonius Lance and Prototype Starglitter are excellent choices, and team compositions should focus on characters that benefit from his shielding and Pyro application. By following these strategies and avoiding common mistakes, you can maximize Thoma's potential and make him a valuable asset to your team.
