A Brief on The Cavern of Corrosion

Cavern of Corrosion is a challenge in the game. You unlock this part of the game from the Trailblazer Mission - The Stars Are Cold Toys, which is a part of the Sweltering Morning Sun storyline. The challenge refreshes daily and allows you to get relics. You will need 40 Trailblazer Power to start the challenge.

To progress in the Cavern of Corrosion, you must raise your Equilibrium level. Each level is based on your Equilibrium Level. There are a total of 12 paths which are unlocked based on your Equilibrium level. From the 12 paths, you can get a total of 24 unique drops or cavern relics.

So, there are a lot of relics. If you want to farm these, you must have Trailblazer power. Trailblazer power is recovered automatically, at a rate of 1 Trailblazer Power per 6 minutes. That is 300 Trailblazer power acquired over a whole day or within twenty-four hours. This game feature will limit you.

To get around this limitation, you are presented with two options:

  • One is to use fuel to get back 60 Trailblazer Power or in other words, 6 hours worth of Trailblazer power.
  • The other way is to use Stellar Jade to replenish it completely. The latter method allows you to replenish Trailblazer Power eight times a day. To get Stellar Jade, complete tasks or do an Honkai Star Rail top up. The best platform to make the top-up is LDShop, it lets players top up for less and is a great way to save money.

The Relics to Farm in the Realm of the Strange 300% Event

With the arrival of new characters like Castorice and Anaxa in version 3.2, you must wonder what the best relics are for them.

We will be going through the best relics for the recent characters like Anaxa and Castorice along with their recommended team members.

For Castorice

If you have pulled Castorice, congrats! Now, how to build her? So she is a DPS main and her main strength lies in her CRIT DMG. So, likewise, she should have a suitable team and relics. Teams for her include RMC, Pela, Lynx, Tribbie, and Gallagher. We will get into each of her recommended team members soon, but what relics to farm for Castorice?

From this event, the best relic you can get for her is the Poet of Mourning Collapse relic set. It also works well for Castorice, Jade, Tribbie, and Qingque. The effects are as follows:

  • With the two-piece set, it will increase the Quantum DMG by 10%.
  • With the whole set, you will see a decrease in the SPD stats. But, if your SPD is less than 110/95, then your CRIT rate is increased by 20 to 32%.

This set increases the CRIT Rate for her memosprite and herself. Hence, it is the best set for Castorice. To make the most use of this set, avoid getting SPD stats, and keep it below 110/95.

For Anaxa

Like Castorice, Anaxa is also a Main DPS. He also has a bonus ability to inflict Qualitative Disclosure on the opponent. So, if you are looking to build him, your main aim should be to increase the CRIT Rate over DMG. He will get CRIT DMG from the bonus ability.

Anaxa works well with a lot of characters, namely, RMC, Asta, Lynx, Sunday, Robin, Huohuo, Herta, Tribbie, and Lingsha. So, what are the relics to get for Anaxa? The best relic to farm for Anaxa in this event is the Genius of Brilliant Stars relic set. The relic provides the following boosts:

  • With two pieces of the set, you will see an increase of 10% on the Quantum DMG of your character.
  • With the whole set, whenever your character deals damage to an enemy, it will ignore 10% of the DEF. But, this effect does not work on opponents who are weak to Quantum.

For Remembrance Trailblazer (RMC)

RMC is the best free-to-play support character for both Castorice and Anaxa. For the RMC, only one relic set stands out in this event. It is the Hero of Triumphant Song relic set. The set gives the following effects:

  • With the two-piece set, you will see an increase of 12% in ATK.
  • With the whole set, your memosprite should be out on the field. When your memosprite is out, your SPD increases by 6%. Whenever your memosprite attacks, it increases both your and your memosprite’s CRIT DMG by 30% for two rounds.

It is also a great set for Aglaea.

For Tribbie

If you’ve got Tribbie, she is a great support character for both Castorice and Anaxa. She can work with any team, and deal a great deal of damage. You should aim to build her as a sub DPS, to support the main DPS. She also works well in dual DPS team lineups. For her, the best relic to get from this event is the Poet of Mourning Collapse, the same as Castorice.

For Lynx

Lynx is one of the best free-to-play healers for your teams with Castorice and Anaxa. You should focus on pushing her speed and healing stats. The Messenger Traversing Hackerspace is the best relic to get for her from this event. The set gives the following boosts:

  • With two pieces of the set, you will see an increase of 8% on the SPD of your character.
  • With the whole set, when you use your ult on an ally, the SPD of all allies increases by 12% for 1 turn. It is not stackable.

For Pela

If you are looking for another free-to-play support character to join your Castorice team, Pela is the best bet. Pela is a debuffer, so her best relic from this event is the Eagle of Twilight Line relic set. It has the following effects:

  • With the two-piece set, there is an increase of 10% in Wind DMG dealt.
  • With the whole set, whenever Pela uses her ult, the action is advanced by 25%.

For Gallagher

Gallagher is the best healer or sustains character to get for your team with Castorice. To be honest, he is one of the best in the game. You should focus on his Break effect stats and his SPD stats. For his SPD stats, the Messenger Traversing Hackerspace relic set is, the same as Lynx. To increase his break effect, go for the Passerby of Wandering Cloud relic set.

  • The two-piece set increases the healing by 10%.
  • The whole set causes an immediate regen of one skill point at the start of a battle.

For Gallagher, it is best to go for two pieces of the Messenger set and two pieces of the Passerby set.

For The Herta

The Herta is the best for a dual DPS team, along with Anaxa. So, here you will need a CRIT DPS build. From this event, the best relic to get her is the Scholar Lost in Erudition relic set. The set gives the following effects:

  • With the two-piece set, you will see an increase of 8% in the CRIT rate.
  • With the whole set, there is an increase in the DMG by 20% for the skills and ult. Moreover, after using the ult, the DMG dealt is increased by 25% for the next skill.

For Lingsha

Continuing with the dual DPS team with Anaxa, Lingsha will be the best sustain or healer. Your main focus should be on the SPD and break effect. So, you can go with the same relic set at Gallagher or a better option would be the Iron Calvary Against the Scourge relic set. It has the following effects:

  • The two-piece set increases Lingsha’s Break Effect by 16%.
  • With the whole set, there are two conditions. If your Break effect is above 150, the Break DMG will disregard 10% of the DEF of the enemy. If your Break Effect is above 250%, the Super Break DMG dealt will disregard 15% of the DEF of the opponent.

Similar to Gallagher, for best results use two pieces of the Messenger set and two pieces of the Iron Calvary set.

For Sunday

Sunday is a great support for the team with Anaxa. His build requires CRIT DMG. So, the best relic from this event is the Sacredos’ Relieved Ordeal relic set. The set gives the following effects:

  • Two pieces of the set will increase the wearer’s SPD by 6%.
  • With the whole set, whenever you use a skill or ult on an ally, it increases the CRIT DMG of the ally by 18% for two rounds. It is stackable for two rounds.

For Robin

Like Sunday, Robin is also a great support for your team with Anaxa. ATK should be your main focus here. For increasing ATK, you have two great relics in this event. One is the Prisoner in Deep Confinement Set and the Musketeer of Wild Wheat set. Both the sets are good on their own, but for best results use two pieces from each set to maximize the increase of ATK stats.

For Huohuo

Another great healer for the team with Anaxa is Huohuo. You will have to focus on building the SPD stats. Like Lynx, the best relic you can get for her from this event is the Messenger Traversing Hackerspace relic set.

 

For Asta

If you are searching for a free-to-play support character for the team with Anaxa, then build Asta. For Asta, you must build the SPD stats to fit in more turns in one cycle. Here too, the Messenger Traversing Hackerspace relic set will be the best.

 

Conclusion

HSR relics determine whether you break and make the game. A good combination of relics and character builds will push you really far, with relative ease. But, at the end of the day, ensure you have fun. May your pulls on the current and upcoming banners be fruitful and get you the characters you want.
