Into the Unreachable Veil Light Cone: HSR Guide

The “Into the Unreachable Veil” is a 5-star Light Cone in Honkai: Star Rail, and its answer is simple: it is the signature Light Cone for the character Dr. Ratio, a follow-up attack-focused Hunt character, and it is also the best general-purpose Light Cone for any Hunt character who relies on follow-up attacks. This article explains exactly what the Light Cone does, who can use it, and how it compares to other options.

Background and Lore

Introduced in Version 1.6 alongside Dr. Ratio, “Into the Unreachable Veil” is a Hunt-class Light Cone with a base HP of 952, ATK of 582, and DEF of 463 at Level 80. Its name and flavor text reference Dr. Ratio’s philosophical outlook—the “unreachable veil” symbolizes the unknown truths he seeks to uncover through logic and reason. In the game’s lore, Dr. Ratio is a member of the Intelligentsia Guild who believes that knowledge should be pursued relentlessly, and this Light Cone embodies that pursuit by rewarding aggressive, follow-up-based combat.

How the Light Cone Works

The Light Cone’s passive ability, “Unveil,” increases the wearer’s CRIT Rate by 18% at Superimposition Level 1 (up to 30% at Superimposition Level 5). Additionally, when the wearer uses their Ultimate, it increases the DMG of their follow-up attacks by 30% for 2 turns (up to 50% at S5). This effect is straightforward: it boosts both the chance to land critical hits and the damage of follow-up attacks, which are the core of Dr. Ratio’s kit.

For Dr. Ratio, who triggers follow-up attacks after using his Skill and Ultimate, this Light Cone synergizes perfectly. The CRIT Rate boost helps stabilize his damage, while the follow-up DMG boost amplifies his most frequent source of damage. For other Hunt characters, the CRIT Rate is always valuable, but the follow-up DMG boost only applies if they have follow-up attacks in their kit or via relics like the Pioneer Diver of Dead Waters set.

Who Should Use It

This Light Cone is the best-in-slot for Dr. Ratio, but it is also a strong option for several other Hunt characters:

• Dr. Ratio – The intended user; the passive aligns perfectly with his kit, making it his undisputed best choice.
• Topaz & Numby – Topaz’s Numby performs follow-up attacks on every turn, so the follow-up DMG boost applies almost constantly, making this a top-tier option for her as well.
• March 7th (Hunt) – Her enhanced state triggers follow-up attacks, so she can benefit, though her base CRIT Rate is low, so the CRIT Rate boost helps.
• Other Hunt characters – For characters like Seele, Yanqing, or Sushang, the CRIT Rate is useful, but they lack reliable follow-up attacks, so the second half of the passive is wasted. In such cases, a Light Cone like “Cruising in the Stellar Sea” (a free 5-star from Herta’s Store) may be more consistent for overall damage.

How to Obtain It

“Into the Unreachable Veil” is a limited-time Light Cone that appears on the “Brilliant Fixation” banner during Dr. Ratio’s debut banner. It is not available in the standard banner or the Starlight Exchange, so players must pull for it during its featured window. As with all limited Light Cones, it may return in future reruns, but there is no confirmed schedule. For players who missed it, the free 5-star “Cruising in the Stellar Sea” from Herta’s Store is a solid substitute for Dr. Ratio, offering CRIT Rate and ATK boosts that are easy to maintain.

Comparison with Other Light Cones

To understand its value, compare it with other Hunt Light Cones:

• vs. Cruising in the Stellar Sea (S5) – This free Light Cone gives 16% CRIT Rate and increases ATK by 32% when an enemy’s HP is below 50%, plus a CRIT Rate boost on kill. For Dr. Ratio, “Into the Unreachable Veil” (S1) provides 18% CRIT Rate (2% more) and a 30% follow-up DMG boost, which is more impactful than the ATK boost in most scenarios. However, Cruising is free, so it is the best budget option.
• vs. Swordplay (S5) – Swordplay increases DMG by 8% per hit, stacking up to 5 times (40% total). For characters with multi-hit attacks, this can rival the Veil, but it lacks the CRIT Rate, making it less consistent for Dr. Ratio.
• vs. Sleep Like the Dead – This Light Cone gives 30% CRIT DMG and a 36% chance to inflict a “Mishap” that increases CRIT Rate by 12%, but it is conditional and less reliable than the Veil’s direct CRIT Rate.

In summary, “Into the Unreachable Veil” is the strongest Hunt Light Cone for follow-up attackers, but for non-follow-up characters, it falls behind more universal options.

Common Mistakes and Misconceptions

A common mistake is assuming the follow-up DMG boost applies to all attacks. It only applies to follow-up attacks (those triggered by talents or certain relic sets), not to basic attacks, skills, or ultimates. Another misconception is that the CRIT Rate boost is enough to make it the best for every Hunt character—this is false because the follow-up DMG portion is wasted on characters without follow-ups, making it less efficient than other Light Cones that provide a more universal damage boost.

Additionally, players often overlook that the follow-up DMG boost lasts for 2 turns after using the Ultimate. This means the character must use their Ultimate before the follow-up attack to benefit, which is natural for Dr. Ratio but may require timing for others.

Is It Worth Pulling?

For Dr. Ratio mains, yes—it is a significant damage increase over his second-best option, “Cruising in the Stellar Sea.” The CRIT Rate and follow-up DMG combine to boost his overall DPS by roughly 15-20% in typical rotations. For players who do not have Dr. Ratio, it is still a great Light Cone for Topaz, but if you have neither, it is better to save your Stellar Jades for other limited Light Cones that benefit your roster more broadly.

As with all limited banners, there is no guarantee of obtaining the Light Cone without spending, so plan your pulls carefully. The pity system ensures a 5-star Light Cone within 80 pulls, but it may not be the featured one.

Frequently Asked Questions

Is “Into the Unreachable Veil” good for Seele?

It is not ideal. Seele does not have follow-up attacks, so the follow-up DMG boost is wasted. The CRIT Rate is useful, but Light Cones like “In the Night” (her signature) or “Cruising in the Stellar Sea” provide more consistent damage boosts.

Can I get this Light Cone from the standard banner?

No. It is a limited-time Light Cone that only appears on the Brilliant Fixation banner during its featured period. It is not in the standard “Stellar Warp” pool.

What is the best Light Cone for Dr. Ratio if I don’t have this one?

The free “Cruising in the Stellar Sea” from Herta’s Store is the best free option, as it provides CRIT Rate and ATK boosts that are easy to maintain. Other good 4-star options include “Swordplay” and “Only Silence Remains.”

Does the follow-up DMG boost stack with other sources?

Yes, it stacks additively with other follow-up DMG boosts, such as those from relic sets or other Light Cone effects. For example, if you have a 30% boost from this Light Cone and a 20% boost from a relic set, your total follow-up DMG increase is 50%.

How many pulls do I need to guarantee this Light Cone?

The hard pity for a 5-star Light Cone on the Brilliant Fixation banner is 80 pulls. However, there is a 75% chance it will be the featured Light Cone, so you might need up to 160 pulls to guarantee it if you lose the 75/25 once.

Is this Light Cone good for future Hunt characters?

It depends on whether they have follow-up attacks. If a future Hunt character has a follow-up mechanic, this Light Cone will likely be a top-tier option. If not, it will be less valuable. Keep an eye on the character’s kit before pulling.
