Raven is one of those systems in Last Asylum Plague that many players underestimate early on. At first it looks like just another progression mechanic sitting quietly in your base. But once you start upgrading it, you quickly realize how much impact it has on combat efficiency and overall progression.
The trick is knowing where Raven resources actually come from and how to collect them without wasting stamina, points, or event rewards. A lot of players struggle because they rely on only one or two sources. In reality, Raven progression becomes smooth when you combine several systems together.
Let’s go through the most reliable ways to upgrade your Raven and obtain Raven gear chests.
Daily Rewards
The simplest way to collect Raven Essence is through daily task rewards.
Every day you can complete routine tasks that generate activity points. Once you reach 60 points, the reward chest grants a total of 6 Raven Essence.
It may not look like a huge amount at first, but daily rewards are extremely important because they are guaranteed and repeatable. Over time those small amounts stack up into a steady supply.
Players who consistently complete their daily activity goals often upgrade their Raven much faster than those who skip these tasks.
Alliance Shop
The Alliance Shop is another reliable place to purchase Raven Essence.
Each essence costs 990 Alliance Points, and buying 10 requires 9,900 Alliance Points. These points come from several alliance activities, including:
- Donating to alliance research
- Donating trap cheese
- Alliance duel weekly rewards
- Thief Hunt rankings
- Celia’s Hunting event
- Pandemic Experience alliance difficulty clears
- Caravan trade activities
Because alliance points are earned from many sources, active players usually accumulate them quickly.
If Raven progression is your priority, spending alliance points here is often one of the best uses for them.
Pandemic Experience Event
During the Pandemic Experience event, alliances can earn additional rewards by clearing higher difficulty stages together.
Completing these challenges grants Alliance Points, which can then be used to purchase Raven Essence from the alliance shop.
The higher the difficulty your alliance clears, the better the rewards become. Strong alliances can farm large amounts of points during this event.
Because it doesn’t appear all the time, it’s worth participating whenever the event becomes available.
Alliance Caravan
The Alliance Caravan activity also provides chances to obtain Raven-related rewards.
Caravan runs give resources and sometimes gear chests. The leader usually receives slightly better rewards compared to regular participants.
Although some rewards are random, participating regularly still increases your chances of obtaining Raven-related items over time.
Expedition Shop
You can earn Expedition Points by completing watchtower activities. These points are then used in the Expedition Shop.
Raven Essence can be purchased here, and buying 30 essence costs around 9,000 points.
For players who actively participate in expedition activities, this shop becomes another reliable way to build up Raven resources.
Honor Shop
Honor Points are earned from competitive events such as:
- Elixir battles
- Royal City Scramble
- Destiny Arena
- Triangular Arena
These points can be spent in the Honor Shop, where Raven Essence is sometimes available.
However, this option is more flexible. Some players prefer spending honor points on other rewards, so purchasing Raven Essence here is usually a matter of personal strategy.
Thief Hunt Event
The Thief Hunt event provides another opportunity to obtain Raven-related rewards.
Players earn Lion Coins by defeating enemies during the event, especially:
- Gold Thieves
- Thief Leaders
Raven Essence exchanges during this event typically require 10,000 Lion Coins for 50 essence.
Because these enemies give higher event points, targeting them is the fastest way to accumulate Lion Coins.
Diamond Purchases
For players willing to spend diamonds, Raven Essence can also be purchased directly.
Buying 50 Raven Essence costs around 19,900 diamonds.
This method is generally used by heavy spenders who want to accelerate Raven upgrades quickly. Free-to-play players usually rely on events and shops instead.
Best Enemies for Raven EXP and Progress
When it comes to farming Raven-related experience and rewards, certain enemies are more efficient than others.
Resource Monsters are recommended mainly for new players. They provide reasonable rewards early on but become less efficient once stronger enemies are available.
For stronger players, Elite Blight level 21 or higher becomes a better target. These enemies provide more experience than high-level resource monsters and are more efficient for stamina usage.
Another important enemy type is Wandering Blight. The first kill of the day usually provides better rewards compared to other targets, so hunting these enemies when they appear on the map is always worthwhile.
Events That Reward Raven Progress
Several limited events indirectly support Raven upgrades.
One of the most useful strategies is saving stamina until events like Thief Hunt or Pandemic Experience begin. Using stamina during these events generates extra event currency, which can later be exchanged for Raven resources.
Another notable event is Celia’s Hunting Day, where players fight the Blighted Countess. This event lasts only two days but offers valuable random rewards including recruit tickets, alliance points, and speedups. Up to 20 rallies per day can be launched during the event.
Falcon Activities and Sanctuary Sources
Some Raven resources also appear in smaller amounts through regular gameplay systems.
Falcon Quests occasionally provide Raven-related rewards as part of their mission payouts.
Additionally, certain rewards can appear inside the Sanctuary or Clinic systems, depending on your base progression and available activities.
While these sources are not the primary way to farm Raven resources, they still contribute to overall progress.
Best Ways to Get Raven Gear Chests
Raven Gear Chests are extremely valuable because they contain equipment used to strengthen the Raven system.
Several places offer these chests.
The Alliance Shop allows players to buy Level 1 Raven Gear Chests, with 20 chests costing around 19,800 alliance points.
The Expedition Shop is another excellent option. Each exchange costs around 200 points, and purchasing multiple chests usually totals about 600 points. Many players consider this one of the best-value purchases available.
Other sources include:
- Covert Operations
- Falcon activities
- Pirate Legacy rewards
- Alliance Caravan rewards (random drops)
Because these sources are partly RNG-based, consistent participation increases your chances of receiving Raven gear.
Tactical Supply and Secret Rewards
Additional Raven gear can appear through special reward systems.
Tactical Supply is earned through competitive events such as:
- Alliance Duel
- Destiny Arena
- Triangular Arena
Meanwhile, Secret Rewards can appear through systems like:
- Covert Ops Force
- Falcon events
- Gear Pass
- Hero Pass
These rewards are less predictable but can provide useful Raven materials.
Raven Workshop – Improving Production Efficiency
Inside your base, the Raven Workshop is responsible for generating Raven-related outputs.
Upgrading this building reduces the production time, allowing you to collect resources more frequently.
While it may not produce huge amounts instantly, upgrading the workshop ensures a steady supply over the long term.
Best Events for Raven Gear Chests
Certain events provide particularly strong rewards for Raven progression.
Alliance Duel is one of the most important ones. Milestones such as:
- 550,000 points
- 2,280,000 points
- 3,620,000 points
- 7,190,000 points
offer increasingly valuable rewards including Raven gear chests.
Another great event is Pandemic Experience, where clearing difficulty level 5 or higher grants Raven gear chest rewards.
Participating in these events regularly can dramatically speed up Raven development.
The Raven system may seem complicated at first, but progression becomes straightforward once you focus on the most efficient sources.
Complete daily tasks to collect Raven Essence consistently.
Spend alliance points in the alliance shop whenever possible.
Participate in events like Thief Hunt and Pandemic Experience.
Farm stronger enemies such as Elite Blight and Wandering Blight.
Purchase Raven gear chests from the Expedition Shop and Alliance Shop.
By combining these sources instead of relying on just one, Raven upgrades become much faster and far more manageable.
Over time, a well-developed Raven system will noticeably improve your combat strength and help you dominate tougher battles across the wasteland.
