How to Beat Avenger's Hospitality

Choose Any Ultimate or Dexterity Gears

The stage directly supports the Ultimate and Dexterity Gears. So, when you talk to Ray at the choose those specific buffs to breeze through the stage quickly.

Choose Sustain and CRIT Resonia

During the challenge, it's best to choose a lot of Resonia that can save your team's health, like HP or Shield ones, since you'll be fighting various bosses.

The bosses before the Sweeper Final Boss are the Notorious Dead End Butcher, Sacrifice Bringer, Nineveh, and Geppetto. That's why it's crucial to balance out the sustain and CRIT buff during this stage.

Use AoE Attacks On Final Boss

The final boss is a Sweeper enemy in the starting area and is seeking ''revenge'' against proxies for becoming a dummy for attacks. One thing to note in this stage is that more will spawn after you beat the first sweeper enemy.

It's best to group them and unleash combos to defeat them in one fell swoop!

At the Cost of Life Guide

At the Cost of Life Hollow Intel

• Carrying this Card into the Hollow will undoubtedly be extremely perilous - So, the depot has also prepared 5 Ether Dewdrops.
• Friendly Talk areas no longer provide HP Recovery.

At the Cost of Life Exclusive Supplies

Supply	Exclusive Supply Effect
Reckless Warrior	When current HP exceeds 10% of Max HP, it will be reduced to 10%. All squad members take more DMG, but attacks are guaranteed to trigger critical hits and their ATK and Anomaly Proficiency are increased.

How to Beat At the Cost of Life

Avoid Getting Hit By Enemies

During this stage, you only have a fixed 10% HP. This would mean the elite enemies and bosses can one-shot you. So, you must dodge or use Perfect Assists or Ultimates to avoid getting hit.

Bring a Bangboo or Agent Best for Sustain

It's best to use Bangboos like Avocaboo or Exploreboo and Agents like Caesar, Seth, or Astra to make sure that if you do get hit, you'll survive it.

Avoid Combat Stages

Avoid going through Combat Stages on the way to the Final Stage as much as possible. This would make it easier to avoid using up the Five Ether Dewdrops in your possession just in case you die in the Final Stage against Geppetto.

Do Not Choose the Adversity Gears

Avoid Adversity gears like Combat Nutrient Pack and Emblem of Calamity since Brawlboo will diminish 30% HP from all party members to deal DMG on the enemies.

How to Beat Strategic Standby

Plan Your Route to Avoid Most Combat

All Hollow Intel and Exclusive Supplies all point to avoiding combat areas as much as possible. Choose non-combat areas as this will increase Gear Coin earnings and CRIT Rate as well as reduce DMG to agents!

Save Ultimate For Elite or Boss Enemies

Since you get fewer chances for combat, avoid using your ultimate when up against normal enemies and use them on elite or boss enemies instead.

Avoid Price Difference Areas

While it's best to go through all combat areas, try to avoid areas marked with a purple lightbulb symbol since that could have encounters that would result in both a buff and a debuff.
