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.
While building as much Elemental Mastery (with enough Energy Recharge) as possible is optimal for damage, you may use some HP% main stats 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 is worth keeping in mind that Burgeon deals self-damage.
Thoma's talent levels do not contribute towards his Burgeon damage, so leveling them is optional in this respect. However, you may still wish to level them for stronger shielding.
