Is Thoma Viable as DPS?
No one will stop you if you want to build Thoma as DPS, though honestly it won’t be as good as other character because his DPS windows only happen during his burst when his Normal Attack infused with Fiery Collapse which have low multiplier (check screenshot above).
Fiery Collapse also happen every 1s so not every hit will trigger this effect.
His best build would be shield and elemental reaction support with his shield from elemental skill and burst.
Thoma have high energy cost and his shield scales off max HP, so for weapon with Energy Recharge or HP from substats or passive is the best for him.
Starting with expensive 5 star option, Staff of Homa will increase Thoma HP by 20% and Vortex Vanquisher can increase Thoma shield strength by 20/25/30/35/40% depend on refinement level.
Both Engulfing Lightning and Skyward Spine have Energy Recharge substats which helps a lot considering Thoma elemental burst have 80 energy cost.
For cheaper 4 star option your first choice and most recommended is The Catch, f2p polearm which can be obtained from Fishing system and easy to refine. This polearm have Energy Recharge substats and it’s passive will increase Elemental Burst DMG and CRIT Rate.
Other option is Favonius Lance which have effect to generate a small amount of elemental particles for faster energy recharge and Prototype Starglitter from blacksmith forging.
If you insist to play Thoma as DPS, your first choice would be 2 Crimson Witch of Flames + 2 Noblesse Oblige. 2 Crimson will boost Thoma Pyro DMG by 15% while 2 Noblesse will increase his Elemental Burst DMG by 20%.
Your second option as burst or DPS is 4 Emblem of Severed Fate. 2 set will give Thoma 20% more Energy recharge, and 4 set will increase his elemental burst DMG by 25% of Energy Recharge (max 75%).
If you want to go all out using Thoma as support, it’s recommended to use 4 Noblesse Oblige.
2 set will increase Thoma Elemental Burst DMG by 20% and it’s 4 set will increase all party members ATK by 20% for 12s when Thoma using elemental burst.
Another option is balanced set of 2 Tenacity of the Millelith + 2 Emblem of Severed Fate. 2 Millelith will increase Thoma HP by 20% and 2 Emblem will increase his Energy Recharge by 20%.
For DPS build
(not recommended), go with usual Pyro DMG% for goblet and CRIT DMG/CRIT Rate% for circlet. For Sand, if you have enough ER you can go for HP% but if you have low ER it’s recommended to use Energy Recharge%.
|HP%/Energy Recharge%||Pyro DMG Bonus%||CRIT Rate%/CRIT DMG%|
|CRIT Rate% > CRIT DMG% > HP% > Energy Recharge% > HP flat|
For shield and support build (recommended) you can go all out with HP%.
|HP% > Energy Recharge% > HP flat > CRIT Rate% > CRIT DMG%|
