Chasmic Altar Event Guide – Defend Esperia From the Devourer!

Here is Borderpolar's complete guide to the new Chasmic Altar event in AFK Arena. This event looks like the Abyssal Expedition as you see a boss on top of an altar on your map, but it's a single boss fought across all servers to decrease campaign difficulty for everyone. Players have to cleanse 5 altars in total, and cleansing an altar moves the event to the next phase where the Gould – The Devourer will cast a different debuff on your team.

The Chasmic Altar Event Took Place in April 2021, so I assume the Cleansed Realm appeared on AFK Arena's world map on May 2021.

Chasmic Altar Formation Recommendations per Phase

Chasmic Altar – Phase 4 Best Team Comps (Normal Attack Damage Only)

Ideally, you want to use Saurus in one team for healing and damage and Raku in the other one as his normal attacks are insane. I don't have Raku, so my options were quite limited here.

Wu Kong is also pure gold here due to his clones. The damage is insane. Albedo and Ainz teams are only great if you have Albedo's SI +30 as it buffs dimensional hero damage and Ainz wrecks. If you have her with SI +30, you can even go full-dimensional. Otherwise, avoid these teams and try conventional formations.

Joker is viable even if not ideal due to his fast attacks, especially at SI +20 and higher.

I highly recommend leaving the first team intact and toying around with the second team. The 1st team comp got me to second place on the server even though my Raine is not 3/9 Mythic Furniture.

If you have any other formation recommendations please leave a comment!

The Devourer's skills

Chasmic Altar Rules

1. The Devourer is invading Esperia. Arden has sensed the impending danger and has called upon all living beings to band together to protect the realm.

2. The Devourer's HP is determined by the number of active players across all servers.

3. Players can cleanse the Corrupted Altars within the Chasmic Altar by assailing The Devourer.

4. Cleansing the Corrupted Altars helps reduce the difficulty of Campaign stages across all servers by granting players Purifying Power. Players can gain more Purifying Power by cleansing more Altars.

5. With the help of Purifying Power, Campaign stage enemies' levels can be reduced according to how many players have completed it. More players who have completed a certain stage will further reduce its difficulty.

6. Damage dealt to The Devourer will be converted into Contribution Points, which will then be permanently recorded on the leaderboard.

7. Players who attack The Devourer will get different rewards based on their contribution Point ranking.

Chasmic Altar Reward Rules

1. The highest amount of damage a player deals with The Devourer will convert into Contribution Points, which will later be permanently recorded on the leaderboard.

2. The daily top 10 ranked players of each server will be awarded the title “Pioneer' and a Limited-Time Medal (2 days) as rewards.

3. Besides ‘Pioneer,' players will be divided into Diamond, Gold, Silver, Bronze divisions. Gold, Silver and Bronze divisions shall each be
respectively split into 2 smaller sub-divisions.

4. Based on a player's daily division ranking, players can acquire Essence, Hero Experience, Gold, a Common Hero Scroll, etc. Rewards will be calculated daily at 00:00 UTC.

5. The Top 10 players will receive a limited edition avatar frame based on final Contribution Point rankings across all servers. The top 1000 players will receive a Limited-Time Medal (6 months) when the event ends.

6. Rankings within the leaderboards are subject to constant changes. Thus, leaderboard rewards will only be finalized when the final leaderboard rankings are calculated.
