Recommended Heroes for Ring of Bulwark

Rudy, Evan, and More

The Ring of Bulwark is especially recommended for heroes like Rudy and Evan who frequently stack Defense. Legendary rings always take priority, but don't hesitate to use Rare rings when they're short.

Recommended Refining and Crafting for Ring of Bulwark

Durability Ring Refinements Recommended

Since this ring is equipped on heroes with high Defense, Refinement Ring of Tenacity — which triggers healing — is the top pick for further increasing durability. Ring of Protection (Defense Boost) and Ring of Bulwark (Block Rate Boost) are also solid secondary choices.

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.

How to Get Ring of Bulwark

Drops from Adventure Nightmare

Accessory Rank by Area

Accessories have a chance to drop when you clear Adventure Nightmare stages. Nightmare becomes available after clearing Adventure 14-50, and the rank of dropped accessories increases as you advance through stages.

Equip a Pet with Equipment Drop Rate UP

Pets with Equipment Drop Rate UP
Mog (up to 30% UP)	Doo (up to 10% UP)

Nightmare uses a 2-round format that requires 2 parties. By including Mog or Doo in one of your parties, you can boost the accessory drop rate.

Point!	Doo can be obtained through Pet Conversion. Mog and Doo's effects do not stack, so only bring one of them.

Advent Expedition Ranking Rewards

You can earn Rare Accessory Boxes from the Advent Expedition ranking rewards. Rankings are determined by the damage dealt to the God of Destruction after defeating the 4 Shadows of Destruction.

Exchange at Guild Shop

You can exchange God of Destruction Fragments (earned from Advent Expedition individual rewards) for a ★5 Rare Accessory Box. However, other rewards such as Old Four Emperors Summon Cards and Equipment Boxes are generally recommended first.

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.
