How do I optimize Thoma's shield and Pyro application in Genshin Impact?

To optimize Thoma's shield and Pyro application in Genshin Impact, you need to focus on his abilities, team composition, and artifact and weapon choices. Thoma is a 4-star Pyro polearm user who excels as a support character, providing strong shields and consistent Pyro application. His shield is tied to his Elemental Skill and Burst, making energy management and cooldown timing crucial. HereÔÇÖs a detailed guide to help you maximize his potential.

First, letÔÇÖs break down ThomaÔÇÖs mechanics. His Elemental Skill, Blazing Blessing, creates a shield that scales off his Max HP. This shield absorbs damage and applies Pyro to nearby enemies upon activation. His Elemental Burst, Crimson Ooyoroi, creates a secondary shield that refreshes every second and deals Pyro damage to nearby enemies. This ability allows Thoma to apply Pyro consistently, making him a great enabler for elemental reactions like Vaporize or Overload. To optimize his shield strength, you need to prioritize HP% stats, as his shields scale directly with his Max HP. Additionally, his Pyro application relies on his Burst uptime, so Energy Recharge is essential to ensure he can use his Burst frequently.

For step-by-step strategies, start by focusing on ThomaÔÇÖs talent upgrades. Prioritize his Elemental Skill and Burst, as these are the core of his shield and Pyro application. His Normal Attack talent is less important unless you plan to use him as a main DPS, which is not recommended due to his low damage output. Next, build his artifacts to maximize HP% and Energy Recharge. A 4-piece Tenacity of the Millelith set is ideal for Thoma, as it boosts his HP and provides a team-wide ATK buff when his Elemental Skill hits enemies. Alternatively, a 2-piece Tenacity of the Millelith and 2-piece Emblem of Severed Fate can work well, balancing HP and Energy Recharge. For main stats, aim for HP% on the Sands, HP% or Pyro DMG Bonus on the Goblet, and HP% or Healing Bonus on the Circlet. Substats should prioritize HP%, Energy Recharge, and flat HP.

Weapon choice is also critical. Thoma benefits from polearms that provide Energy Recharge or HP. The Favonius Lance is an excellent option, as it generates energy particles for the team and helps Thoma maintain his Burst uptime. The Black Tassel is another good choice, offering a significant HP boost to strengthen his shields. If you have access to 5-star weapons, the Staff of Homa is ideal, as it provides both HP and Crit DMG, enhancing ThomaÔÇÖs overall utility.

In terms of team composition, Thoma works best in teams that rely on Pyro reactions. For example, pairing him with Hydro characters like Tartaglia or Ayato can create consistent Vaporize reactions, significantly boosting team damage. He also synergizes well with Electro characters like Raiden Shogun or Fischl for Overload reactions. ThomaÔÇÖs shields and Pyro application make him a great support for characters who need protection and elemental synergy. Avoid pairing him with characters who rely on Cryo reactions, as his Pyro application can interfere with Freeze or Melt setups.

Common mistakes to avoid include neglecting Energy Recharge, which can leave Thoma unable to use his Burst consistently. Another mistake is focusing too much on damage stats like ATK or Crit, which are less effective for Thoma compared to HP and Energy Recharge. Additionally, avoid using Thoma in teams where his Pyro application might disrupt desired elemental reactions, such as in a Freeze team with Cryo and Hydro characters.

For advanced techniques, consider timing ThomaÔÇÖs Elemental Skill and Burst to maximize shield uptime. Use his Skill to create an initial shield, then follow up with his Burst to refresh the shield and apply Pyro. This ensures continuous protection and Pyro application. Additionally, use his Burst before switching to your main DPS to trigger elemental reactions immediately.

In summary, optimizing ThomaÔÇÖs shield and Pyro application requires a focus on HP, Energy Recharge, and team synergy. Build him with HP% artifacts and Energy Recharge weapons, prioritize his Elemental Skill and Burst talents, and pair him with characters who benefit from Pyro reactions. Avoid common mistakes like neglecting Energy Recharge or using him in incompatible teams. With the right setup, Thoma can provide strong shields and consistent Pyro application, making him a valuable support character in Genshin Impact.
