Honkai: Star Rail Agate (Stoneheart) Leaks: Kit & Design Speculation
The Interastral Peace Corporation (IPC) is one of the most powerful factions in the Honkai: Star Rail universe, and at the top of its hierarchy sit the Ten Stonehearts. We've already met the debt-collecting Topaz, the gambling high-roller Aventurine, and the cunning Jade. Now, whispers from the data-sphere point to the next Stoneheart preparing to take the stage: Agate.
While official details are scarce, the lore crumbs dropped in Penacony and the pattern of IPC character releases allow us to build a compelling picture of what Agate might bring to the game. Will they complete the Follow-Up Attack (FUA) Exodia team? What is their Cornerstone ability? In this guide, we dive deep into the leaks and speculation surrounding Agate.
A Vow of Stone:
The Ten Stonehearts are bound by their Cornerstones. Whether you align with the strategists or the enforcers, you can represent the IPC's elite with the Stoneheart's Oath Ring Series Metal Badges. This collection features the emblems of Aventurine, Topaz, Jade, and hints at the symbols of future members like Agate.
1. Who is Agate? (Lore & Rank)
The "Ten Stonehearts" are high-ranking executives in the IPC Strategic Investment Department, each wielding a Cornerstone granted by Diamond (the Emanator of Preservation). Agate has been mentioned in voice lines and lore texts as a key member of the group.
The Meaning of Agate
In gemology, Agate is often associated with balance, protection, and strength. It is a grounding stone. This suggests that Agate might play a defensive or stabilizing role within the IPC, perhaps acting as the "Shield" to Diamond's "Sword."
Potential Rank & Role
- The Enforcer: Unlike the manipulative Jade or the showman Aventurine, Agate might be a more direct enforcer of IPC will, possibly leading security forces or asset recovery teams.
- The Mediator: Given Agate's balancing properties, they could be the internal affairs officer ensuring the other Stonehearts don't destroy each other.
2. Kit Speculation: The Final Piece of the IPC Team?
The current "IPC Team" (Aventurine, Topaz, Dr. Ratio/Jade, Robin) heavily favors Follow-Up Attacks (FUA). It is highly probable Agate will continue this trend but fill a niche that is currently lacking.
Theory A: The Quantum Shielder
Path: Preservation / Element: Quantum
While Aventurine is an incredible shielder, the game lacks a Quantum Preservation unit with FUA synergy (Fu Xuan doesn't do FUA). Agate could provide shields that reflect damage or trigger FUAs when hit, punishing enemies for attacking.
Theory B: The Physical Harmony
Path: Harmony / Element: Physical
Robin is currently the best support for the IPC team, but she isn't technically a Stoneheart. Agate could be a dedicated "Stoneheart Buffer" who provides specific bonuses based on how many IPC members are in the party, perhaps granting "Debt" stacks or increasing Cornerstone charges.
| Feature | Topaz | Aventurine | Jade | Agate (Speculation) |
|---|---|---|---|---|
| Role | FUA Sub-DPS / Debuffer | Sustain / Sub-DPS | AoE Sub-DPS / Buffer | Crowd Control / Tank |
| Core Mechanic | Proof of Debt (Numby) | Blind Bet (Shields) | Debt Collector (HP Drain) | Asset Freeze (Stun/Delay) |
| Cornerstone | Topaz of Debt Retrieval | Aventurine of Stratagems | Jade of Credit | Agate of Fortitude |
The Golden Standard:
The standard for IPC style is set by Aventurine. If Agate is anything like him, expect a flashy, high-stakes design. While waiting, you can admire the gambler himself with the Honkai: Star Rail Aventurine 1/7 Scale Figure. It's a centerpiece worthy of the Strategic Investment Department.
3. Cornerstone Design: "Agate of Fortitude"
Every Stoneheart has a "Cornerstone" form—a powered-up state where they channel Diamond's authority. For Agate, we speculate a design that embodies impenetrable defense or crystalline structures.
- Visuals: Expect earth tones mixed with IPC's signature gold and white. Agate stones often have banded patterns, which could translate into a layered outfit or armor design.
- Weapon: A heavy weapon like a hammer, shield, or gauntlets would fit the "strength" theme of Agate, contrasting with Topaz's pistol and Aventurine's chips.
4. Release Date Window
HoYoverse tends to release Stonehearts during major arcs involving the IPC.
- Version 3.X (Amphoreus Arc): With the story moving to new planets, the IPC will inevitably be involved. Agate could appear as an antagonist-turned-ally in late 3.X patches (similar to Jade in Penacony).
- Pier Point Arc: The eventual return to the IPC headquarters (Pier Point) would be the most logical place for a mass Stoneheart reveal.
5. FAQ: The Stonehearts
How many Stonehearts are playable?
Currently, Topaz, Aventurine, and Jade are playable. Agate, Obsidian, Pearl, Sugilite, Opal, Amber, and Diamond remain unreleased or NPC-only for now.
Will Agate be a villain?
The IPC are "morally gray." Like Topaz and Aventurine, Agate will likely be an antagonist initially due to conflicting interests with the Astral Express, but not a villain in the traditional sense.
Is Numby a Stoneheart?
No, Numby is a Trotter! But he is the mascot of the group. If you want your own Trotter, check out the Topaz & Numby Happy Shake Figure for some desk-shaking fun.
Where can I buy the Stoneheart Badges?
You can find the official Stoneheart's Oath Ring Series Metal Badges at Bahomu's Honkai: Star Rail Collection.
Conclusion
The Ten Stonehearts are shaping up to be one of the most interesting factions in Honkai: Star Rail. Agate represents the next chapter in this corporate saga. Whether they bring a new shield meta or a unique crowd control mechanic, their arrival will surely shake up the market.
