Rubia is a Physical 
Fire DPS that with all sorts of damaging skills. High damaging DoTs, DEF shred, and evasion makes her a versatile DPS. She does not need dupes to function, with most of her combat power being locked behind potentials. She's a decent DPS with various utilities, but keep in mind that she needs a lot of tears to be good.

Strengths and Weaknesses
＋Rubia is a decent DPS, and most of her combat power is unlockable through potentials instead of dupes.
＋Rubia has the best AoE for a DEF shred costume.
? Rubia is currently untested in Mirror Wars. In theory, her costumes should be good in PvP.
－Conversely, Tears of the Goddess are a scarce resource. Using so many just to make Rubia usable may delay you from upgrading key potentials for other units.
－Rubia is generally outclassed by Liatris as a DPS, and her shred isn't that big an upgrade over Elise, who can shred for 50% without potentials. There is currently no strong justification to invest in her over other Fire DPS units.
Costumes
Rubia currently has 3 costumes. The Thorn of the Desert is a DoT skill, Empress of the Ocean is a wide AoE attack with DEF shred, and Maid Name C is a damaging costume with both a self-buff and evade utility.
Thorn of the Desert
Very Front
Dagger Dance
SP ◆ 4 — CD ● 5 Turns
Attack 3 Times, each attack deals Physical DMG based off of 40% of ATK. Deal Physical DMG based off of 75% of ATK every turn for 3 turns.
Skill Potential 1
Initial DMG +25%
Skill Potential 2
DoT DMG +50%
Skill Potential 3
DoT DMG +50%
| +1 | +2 | +3 | +4 | +5 |
|---|---|---|---|---|
| Physical DMG | Physical DMG | SP | DoT | DoT |
| 40% ▸ 60% | 60% ▸ 75% | 4 ▸ 3 | 75% ▸ 120% | 120% ▸ 165% |
Thorn of the Desert is recruitable in the pub of Story Pack 5.
This costume deals more damage than [Rodev's Star] Liatris, however the pattern is worse than Liatris's 
pattern. The massive multipliers coming from the skill potentials also make this costume more usable at +0.
Key Upgrades: Skill Potential 2 and 3, Design +3, others are nice to have.
Empress of the Ocean
Very Front
Break Bullet
SP ◆ 5 — CD ● 5 Turns
Attack 6 Times, each attack deals Physical DMG based off of 25% of ATK. Reduce DEF by 25% for 4 turns.
Skill Potential 1
DMG +7%
Skill Potential 2
DEF Shred +10%
Skill Potential 3
DEF Shred +10%
| +1 | +2 | +3 | +4 | +5 |
|---|---|---|---|---|
| Physical DMG | Physical DMG | SP | Physical DMG | Physical DMG |
| 25% ▸ 32% | 32% ▸ 39% | 5 ▸ 4 | 39% ▸ 45% | 45% ▸ 50% |
The biggest DEF shred AoE in the game, compared to [Lovely Lady] Elise's skip 
pattern. However, given that shred is only required against elite enemies a lot of the time, the only advantage this costume has over Elise in PvE really is the chain utility. Additionally, you need to use 3 tears to get to 45% DEF shred, since Skill Potentials 2 and 3 are locked behind Skill Potential 1.
This costume is really scary in PvP, however the high SP cost makes it unsuitable for an attack opener. It also completely whiffs its AoE if she targets a backline enemy.
Key Upgrades: Skill Potentials 2 and 3, Design +3, others are nice to have.
Maid Name C
Very Front
[Secret Service] Enhancement
SP ◆ 3 — CD ● 5 Turns
Evade enemy attacks with 100% chance for until 2 successful evasions. Increase ATK by 50% for 4 turns. Attack 2 Times, each attack deals Physical DMG based off of 120% ATK.
Skill Potential 1
DMG +20%
Skill Potential 2
ATK Buff +2 Turns
Skill Potential 3
Evade +1
| +1 | +2 | +3 | +4 | +5 |
|---|---|---|---|---|
| SP Cost | Physical DMG | Physical DMG | Physical DMG | Physical DMG |
| 3 ▸ 2 | 120% ▸ 140% | 140% ▸ 160% | 160% ▸ 180% | 180% ▸ 200% |
Maid Name C's is a cheap skill that offers utility more than damage. Her ATK buff isn't that strong, but it has 100% uptime with skill potential 2. Her evade is also really neat, allowing her to completely evade strong enemy skills, especially those that deal high Fixed or Pure DMG. This evasion is also very annoying to deal with in PvP.
NOTE: Evade does not work in Fiend Hunt!
Key Upgrades: Design +1, Skill Potential 2 and 3
Building Rubia
Rubia has slightly different gear depending on whether you're using her in PvP or PvE.
Carneliana
Exclusive Stat — 45 ATK%
Correct Main Stats — ATK + CDMG
This exclusive weapon is a decent boost to Rubia's DMG. It's definitely nice to have, but not strictly necessary.
Bond Potential
| ATK | 52% |
| HP | 154 |
| CDMG | 47.2% |
| ATK | 116 |
| DEF | 5% |
| - | - |
| ATK | 52% |
| CDMG | 28.4% |
| Fire DMG | 30% |
Maid Name C is Rubia's BiS potential for PvE content, given how useful Advantage DMG is. If you don't have this costume, Thorn of the Desert is a decent alternative.
Use Thorn of the Desert for PvP.
Optimal Build [PvE]
＋
or
＋
Optimal Substat Spread (Assuming BBS Refinements) — 4 ATK% substats + 11 CDMG substats
Refer to the Defensive Gearing section of my gear guide for what body and head pieces to use.
Optimal Build [PvP]
Optimal Substat Spread (Assuming BBS Refinements) — 15 CDMG substats
Use full DEF gear so Rubia won't immediately die to counters.
Using Venomous Touch as your accessory is an okay alternative to Warmth of the Brazier if you already have it for her PvE build, since her costumes are multi-hit skills. It is also completely fine if you have some ATK% substats in place of CDMG substats, since it's very hard to get all 15.
