When Honkai Star Rail's version 2.0 update arrived, the relic farming landscape expanded significantly with two specialized sets aimed at different damage archetypes. The first set, Pioneer Diver of Dead Waters, focuses on exploiting debuffed enemies, while the second set, Watchmaker, Master of Dream Machinations, enhances Break Effect for supports and damage dealers alike. These sets were originally datamined around the 1.6 period, when players were preparing builds for Dr. Ratio and Ruan Mei. Although those characters had temporary options at launch, the 2.0 relic additions eventually offered more precise best-in-slot choices for particular team compositions.
🧩 Pioneer Diver of Dead Waters
This set caters to damage dealers who benefit from conditions such as debuffs, vulnerabilities, and damage-over-time effects on opponents. Dr. Ratio stands out as the primary candidate because his kit rewards attacking enemies that are afflicted by multiple negative statuses. The set can also function for a CRIT-based Kafka build, though Kafka usually prefers damage-over-time scaling. Characters like Topaz, Guinaifen, and Silver Wolf become valuable teammates because they can reliably place debuffs and help the wearer trigger the more powerful four-piece condition.
The set bonuses are as follows:
-
2-Piece Bonus: Increases damage dealt to enemies with debuffs by 12%.
-
4-Piece Bonus: Increases CRIT Rate by 4%. Attacks against enemies with at least 2 or 4 debuffs deal 8% or 12% increased CRIT DMG respectively. Upon inflicting a debuff on an enemy, both the CRIT Rate and CRIT DMG bonuses are doubled for one turn.
| Effect | Condition | Bonus |
|---|---|---|
| Damage boost | Enemy has a debuff | 12% increased DMG |
| CRIT Rate | Wearer equipped with 4-piece | 4% |
| CRIT DMG | Enemy has at least 2 debuffs | 8% |
| CRIT DMG | Enemy has at least 4 debuffs | 12% |
| Bonus doubling | Wearer inflicts a debuff | CRIT Rate and CRIT DMG doubled for 1 turn |
Players who want to maximize this set should coordinate debuff application. A single debuffer may not be enough to maintain the four-debuff threshold, so combining multiple sources such as Silver Wolf's bugs, Guinaifen's Firekiss, Topaz's Proof of Debt, or Dr. Ratio's own debuffs can make the four-piece bonus much more consistent. The doubled bonus after inflicting a debuff also encourages the wearer to have at least one way to apply a negative status themselves.
🕰️ Watchmaker, Master of Dream Machinations
The Watchmaker set is designed for Break Effect-oriented supports and damage dealers. It can be viewed as a direct upgrade to Thief of Shooting Meteor when the energy regeneration from the older set is not required. Ruan Mei benefits heavily from this set because reaching a high Break Effect total is important for her team buffs, and the Watchmaker set can provide a substantial amount without relying solely on substats. A Break Effect Silver Wolf can also use the set, and future Break Effect characters may find it useful as well.
The set bonuses are as follows:
-
2-Piece Bonus: Increases Break Effect by 16%.
-
4-Piece Bonus: When the wearer uses their Ultimate on an ally, Break Effect for all allies increases by 24% for 2 turns. This effect cannot be stacked.
| Effect | Condition | Bonus |
|---|---|---|
| Break Effect | Wearer equipped with 2-piece | 16% |
| Team Break Effect | Wearer uses Ultimate on an ally | 24% for all allies for 2 turns |
| Stacking | Repeated Ultimate casts | Cannot be stacked |
Ruan Mei players often target around 180% Break Effect to fully benefit from her kit. The Watchmaker set's 16% two-piece bonus and the temporary 24% teamwide buff can help reduce the relic substat requirements. The main drawback is that Thief of Shooting Meteor is easy to obtain from weekly Echo of War encounters, so many accounts may already have a decent Break Effect loadout. However, for players who want to push Ruan Mei's support potential in a dedicated team, Watchmaker provides a more focused option.
⚡ Farming and Preparation
Since the release of these sets, farming them in their respective Cavern of Corrosion locations requires Trailblaze Power. Players who planned ahead before the 2.0 patch often stockpiled Fuel and reserved Trailblaze Power to obtain a large number of relics on day one. The same principle still applies when a new account decides to build Dr. Ratio or Ruan Mei: saving energy resources and focusing on the correct Cavern can accelerate the process.
For Dr. Ratio teams, having Topaz, Guinaifen, or Silver Wolf is especially helpful because the Pioneer Diver four-piece bonus depends on maintaining debuffs. For Ruan Mei teams, the Watchmaker set works best when she can use her Ultimate regularly, as the teamwide Break Effect buff lasts only two turns and cannot be stacked.
Ultimately, these two relic sets remain meaningful examples of how Honkai Star Rail's gear system can shape character builds. Pioneer Diver of Dead Waters rewards strategic debuff stacking, while Watchmaker, Master of Dream Machinations pushes Break Effect synergy across the team.
