Raven is one of the most important combat mechanics in Last Asylum.
Raven works as an additional hero for your formation. However, there is one major difference: any upgrade made to Raven affects all of your squads. Because of this, upgrading Raven is one of the most important things you can do to increase your overall squad might.
There are four different ways to upgrade Raven and improve its various stats.
1. Leveling Raven Attributes
When you first enter the Raven Nest building, the first section you will see is the Stats section. This is where you can upgrade Raven’s different attributes, including:
- ATK
- HP
- DEF
Leveling Raven’s attributes not only increases Raven’s Might, but also contributes to improving your heroes’ stats, such as HP, ATK, and DEF.
Additionally, leveling Raven’s attributes also upgrades Raven’s Skill, making this an important part of strengthening your overall formation.
Raven Skill
Below is a description of the Raven Skill.
Raven Fireworks
“ Targets 2 enemies with the highest HP, dealing 1124% ATK as Physical DMG (CD:13s) “
Upgrade Preview:
Star Level 1 (Level 30) : Increases damage taken by affected targets by 12% for 5s.
Star Level 2 (At Level 50) : Deals 18% extra damage.
Star Level 3 (At Level 70) : Increases damage taken by affected targets by 15% for 5s.
Star Level 4 (At Level 90) : Extra damage increases to 36%.
Star Level 5 (At Level 110) : Increases damage taken by affected targets by 15% for 7s.
Leveling up Raven increases its Star Level at specific levels. Your goal should be to get Raven to Level 110 as soon as possible to gain the maximum benefits from the Raven Skill.
Leveling Raven requires two main resources:
- Raven Fruit
- Raven Essence
Raven Fruit
Raven Fruit can be obtained through a variety of methods.
- Falcon Quests: One of the best and most consistent sources of Raven Fruit. Completing these quests regularly provides a steady supply.
- Resource Monsters, Elite Blights, and Wandering Blights: Defeating these enemies for the first time each day on the World Map rewards Raven Fruit.
- Thief Hunt: Defeating Gold Thieves and Boss Thieves during the Thief Hunt event provides Raven Fruit.
- Expedition Shop: You can purchase 100,000 Raven Fruit up to 25 times for 2,100 Expedition Medals per purchase. This is one of the best ways to obtain a large amount of Raven Fruit.
Raven Essence
Raven Essence can be obtained from several different sources:

When Should You Use Raven Resources?
When leveling Raven, it is very important to know when to use your Raven Fruit and Raven Essence.
The best time to spend these resources is Day 1 of the Alliance Duel event. Using Raven resources during Alliance Duel provides a large number of points, helping you unlock higher tiers of rewards while also contributing points toward your Alliance’s progress and victory.
Therefore, it is best to save your Raven resources throughout the other days and spend them on Day 1 of Alliance Duel. This allows you to maximize the rewards you receive from the event.
2. Raven Gear
You can make Raven stronger by equipping higher-level Raven Gear.
You can equip a total of 8 pieces of Raven Gear, with each piece providing different bonuses.
| Gear | Bonus |
|---|---|

| Feather | Increases Hero HP |
| Beak | Increases Hero DEF |
| Tail | Increases Raven DEF |
| Claw | Increases Raven ATK |
| Eye | Increases Hero ATK and Hero DMG Dealt |
| Mask | Increases Raven HP, Hero HP, and Hero DEF |
| Cloak | Increases Raven ATK, Hero ATK, and Raven DEF |
How to Obtain Raven Gear Chests
Raven Gear can be obtained from Raven Gear Chests, which are available through several sources:
- Covert Ops: Completing Covert Ops quests can reward Raven Gear Chests.
- Raven Workshop: The Raven Workshop building in your Territory provides a steady source of Raven Gear Chests. Upgrading the building can reduce production time.

When Should You Open Raven Gear Chests?
Similar to Raven resources, it is important to save your Raven Gear Chests for the appropriate Alliance Duel day.
The best time to open Raven Gear Chests is Day 3 of the Alliance Duel event. Opening the chests on Day 3 provides a larger number of Alliance Duel points, allowing you to maximize your event rewards.
3. Raven Evolution
The Raven Evolution feature allows you to further increase Raven’s HP, ATK, and DEF.
It is important to level Raven Evolution to at least Level 10 as soon as possible because reaching Level 10 unlocks the Epigraph mechanic for Raven.
Raven Evolution requires the Raven Evolve Guide item. Additionally, extra Epigraphs that you do not need can also be used to increase your Raven Evolution level.
Raven Evolve Guide
Currently, the Raven Evolve Guide can only be obtained from the Alliance Shop for 1,980 Alliance Coins each.

As you unlock additional Epigraph Plans, you can assign Epigraphs to additional squads.
