Recommended Heroes for Ring of Immortality
Fai, Branze & Bransel, and More
The Ring of Immortality is best for heroes like Fai and Branze & Bransel — attackers with low base durability who need to stay on the field longer. It's especially valuable for heroes who become stronger as the battle goes on.
Be Aware of Heroes Not Recommended for Ring of Immortality
If a hero whose Passive Skill grants Immortality equips the Ring of Immortality, only the stronger of the two effects will activate. If that hero also has an on-Immortality effect, it may fail to trigger. Avoid equipping the ring on the heroes listed above.
Recommended Refining and Crafting for Ring of Immortality
Ring of Authority Recommended
The best Fixed Refinement for Ring of Immortality is the Ring of Authority. Ring of Resurrection is a solid second choice, but since Immortality is often equipped on low-durability heroes and Attackers, Ring of Authority tends to be more useful than Ring of Resurrection, which is better suited for high-durability heroes.
Attacker-Friendly Rings Are Also an Option
If Refinement two Legendary rings together is difficult, consider rings that pair well with Attackers — such as Ring of Roar (generates Barrier based on Attack), Ring of Annihilation (Damage Boost for 4–5 target skills), Ring of Vengeance (Damage Boost), or rings that apply status effects.
Random Conversion requires fewer materials
Fixed Conversion lets you obtain a specific ring, but requires more material rings. With Random Conversion, the ring obtained is random but requires fewer materials, so Random Conversion is recommended unless you are targeting a specific ring.

Adventurer SkillsExchange at Arena Shop

You can exchange for a ★4 Legendary Accessory Box at the Arena content shop. The Winner's Medal cost is high, but it is one of the highest-priority items to exchange for in the Arena Shop.
Arena GuideExchange at Total War Shop

The Total War exchange shop offers ★4–★6 Rare or Legendary Accessory Boxes. Collecting advanced Total War Coins is demanding, but opportunities to obtain ★6 Legendary rings are limited, so it is recommended to save up 2,500 and exchange.
Total War GuideExchange at Topaz Shop

You can also exchange for a ★4 Legendary Accessory Box at the Topaz shop, available through paid purchases. Since it requires 10,000 Topaz, depending on your Topaz balance and progression, it may be better to prioritize other rewards.
Purchase Nightmare Pass

The Premium Pass for Nightmare Pass IV and V also includes ★4 Legendary Accessory Boxes and ★6 Uncommon Accessory Selection Boxes. The other rewards are also generous, so purchasing it is recommended if you don't mind spending.
★6 Legendary Rings Can Be Converted to a Different Type

★6 Legendary rings can be converted into a ★6 Legendary Accessory Selection Box once per month. Use this feature if you didn't get the ★6 Legendary ring you wanted.
