Here's how you can build your f﷽ree five-star Imaginary unit, Dr. Ratio, in Honkai: St♛ar Rail.
Aside from follow-up attacks, his playstyle also takes advantage of debuffs applied to enemies in order to increase his DMG output. He may be a free character, or at least he was for a mlimited time, but his combat capability is far from overwhelming. 🌠Know what it takes to master Dr. Ratio’s kit and he might just give you a passing grade.
6 Pair Him With Characters That Apply Debuffs 𒅌
After using Dr. Ratio’s Skill, Intellectual Midwifery, he has a 40 percent fixed chance of launching a follow-up attack against his target for one time. For each debuff that the target enemy possesses, the chance of triggering this follow-up attack will increase by 20 percent.
After unlocking Dr. Ratio’s second Major Trace, Inference, his Skill can apply a debuff to an enemy target. This debuff re𝕴duces the target’s Effect RES by 10 percent for two 💟turns.
This follow-up attack is how Dr. Ratio will deal most of his DMG, so ensuring that you trigger it is important. 168澳洲幸运5开奖网:Characters that can apply debuffs will be his best teammates, as they can increase the chance of 🦋trigger♈ing Dr. Ratio’s follow-up attack.
Aside from increasing his follow-up attack chance, these effects will also occur when you attack💦 a debuffed target:
- After unlocking his first Major Trace, Summation, when you use Dr. Ratio’s Skill, his CRIT Rate increases by 2.5 percent, and CRIT DMG by five percent. This effect can stack up to six times.
- After unlocking his third Major Trace, Deduction, when Dr. Ratio deals DMG to a target, the DMG dealt will increase by 10 percent, up to a maximum of 50 percent. The target must have at least three debuffs for this to take effect.
5 ♉ Use His Ultimate To Guarantee His Foll🎶ow-Up Attack
When you use his Ultimate, Syllogistic Paradox, Dr. Ratio will attack a single target enemy and apply two stacks of Wiseman’s Folly status to them. When your other party members attack a target afflicted with Wiseman’s Folly, Dr. Ratio will consume one stack and automatically launch his follow-up attack.

Dr. Ratio aims to cleanse the world of ignorance, and to do that he'𝕴ll need the right teammates to aid him.
This allows you to spam Dr. Ratio’s follow-up attacks, regardless of the trigger chance, for two consecutive times, and without needing to wait for his turn. After you use Dr. Ratio’s Ultimate on a target, focus your other characters’ attacks on that target to deal additional DMG.
4 🏅 Use His Technique For An Extra Debuff
Dr. Ratio’s Technique summons a statue of himself. Enemies within a certain radius of the statue will get Taunted, forcing them to attack the statue instead of you. When you enter battle with enemies within the statue’s range, all enemies will have their SPD reduced by 15 percent for two turns.
This SPD reduction is considered a debuff, which contributes to Dr. Ratio’s debuff needs. With his Technique, as well as the Effect RES Reduction from his Skill, you can apply two𒅌 debuffs on enemies from the start.
3 🍬 🦂 Equip His Best Relic Set
With the release of Penacony came two additional Relic Sets, one of them being the Pioneer Diver of Dead Waters, which is Dr. ratio’s best-in-slot set. The set provides the following effects:
- Two-Piece: Increases DMG dealt to enemies with debuff by 12 percent.
- Four Piece: Increases CRIT Rate by four percent. The wearer deals eight percent/12 percent increased CRIT DMG to enemies with at least two/three debuffs. After the wearer inflicts a debuff on enemy targets, the aforementioned effects increase by 100 percent, lasting for one turn.

Here's how to level u𒊎p your🌞 Dr, Ratio to be combat-ready.
The Pioneer Diver of Dead Waters set complements Dr. Ratio’s playstyle perfectly, as he wants to have debuffs on his enemies, and this set increases his DMG, CRIT Rate, and CRIT DMG when attacking debuffed enemies. This set can be farmed from Cavern of Corrosion: Path of Dreamdive🐓, which is located in The Reverie (Dreamscape) in Penacony.
2 Optimiz🔥e His Crit Ratio 🉐
Balancing a characters’ CRIT Rate ♋and CRIT DMG can be dꦛifficult, as it mostly boils down to being lucky with your Relic rolls. However, Dr. Ratio has a ton of CRIT sources, which make building him rather easy:
- Up to 15 percent CRIT Rate and 30 percent CRIT DMG from Summation (first Major Trace)
- 12 percent CRIT Rate from his regular Traces.
- Up to four percent CRIT Rate and 24 percent CRIT DMG from Pioneer Diver of Dead Waters set.
All of these combined can already provide up to 31 percent free CRIT Rate and 54 percent free CRIT DMG, without any Relic stats or 168澳洲幸运5开奖网:buffs from other party members. With these in mind, optimi🦂zing his CRIT Ratio won’t be too much of a 🎀hassle.
1 🌱 Take Note Of How Many Debuffs He Needs 🍬
When selecting Dr. Ratio’s Skill, an effect will appear on top of all enemies, which displays the chance of triggering his follow-up attack on specific targets. When a target has at least three debuffs, or if they’re affected by Wiseman’s Folly after using Dr. Ratio’s ✱Ultimate, “100 percent” will💛 be displayed on top of them, which guarantees Dr. Ratio’s follow-up attack.
For the other parts of his kit, it might be difficult to k🔯eep track of how many debuffs he needs to h🎀ave on his targets in order to maximize them as there are no visual indicators. The requirements for his other effects are:
- First Major Trace (CRIT Rate and CRIT DMG increase) - six debuffs
- Third Major Trace (DMG increase) - five debuffs
- Pioneer Diver of Deep Waters (Relic set) - three debuff
Since his follow-up attack is already guaranteed at three debuffs, you don’t need to achieve all the required number of debuffs for the other parts of his kit. Treat 𒉰them more as a bonus rather than a necessity.
