This section focuses on using Thoma as a trigger for Burgeon. Thoma's slow rate of Pyro application paired with frequent Fiery Collapse triggers make him a great option for Burgeon. Additionally, he provides defensive utility in the form of shields.

Energy Recharge / Elemental Mastery / HP% / HP / CRIT Rate
While building as much Elemental Mastery (with enough Energy Recharge) as possible is optimal for damage, you may use some HP% mainstats if you desire a stronger shield. This can be relevant if running teams without other forms of defensive utility outside of Thoma's shields, and it's worth keeping in mind that Burgeon deals self-damage. Energy Recharge substat until requirement is met. *Crit Rate substat is only useful if using Favonius Lance.

Best Weapons

Base ATK565
Elemental Mastery+110
SourceForging
Samurai Conduct
Increases Elemental Skill DMG by 6~12%. After Elemental Skill hits an opponent, the character loses 3 Energy but regenerates 3~5 Energy every 2s for the next 6s. This effect can occur once every 10s. Can be triggered even when the character is not on the field.
High refinement is recommended to further reduce Thoma's Energy Recharge requirements
Base ATK565
Energy Recharge+61.3%
SourceWish
Windfall
CRIT Hits have a 60~100% chance to generate a small amount of Elemental Particles, which will regenerate 6 Energy for the character. Can only occur once every 12~6s.
If using this weapon, try to build some Crit Rate so Thoma can trigger the passive.
Base ATK454
Elemental Mastery+221
SourceWish
Bane of Flame and Water
Increases DMG against opponents affected by Hydro or Pyro by 20~36%.
Becomes a more reasonable option when you have Thoma's [C4].

Elemental Mastery+110

Stillwood Moonshadow
After triggering Burning, Quicken, Aggravate, Spread, Bloom, Hyperbloom, or Burgeon, a Leaf of Revival will be created around the character for a maximum of 10s. When picked up, the Leaf will grant the character 16~32% ATK for 12s. Only 1 Leaf can be generated this way every 20s. This effect can still be triggered if the character is not on the field.
Base ATK354
HP+46.9%

Bane of the Soft
Increases DMG against slimes by 40~80%.

Tip of the Spear
When the wielder is healed, restore 8~16 Energy. This effect can triggered once every 10s, and can occur even when the character is not on the field.
In teams where you are able to heal Thoma consistently (overhealing also counts), Rightful Reward can be a reasonable option due to the amount of energy generation.
