Last Asylum Plague Raven
The Raven is a combat companion that fights next to your five heroes, and every upgrade you make to it applies to all of your squads. You level it from 1 to 250 with Raven Fruit and Raven Essence, evolve it to open Epigraph Plans, and equip it with six pieces of Raven gear. This page lists the cost, the sources and the bonus of each step.
How the Raven Works
The Raven attacks enemies for the whole battle and takes no damage. Part of its HP, ATK and DEF converts into the stats of all your heroes during a fight, so a stronger Raven lifts every squad at once. Total Might counts it as one of five sources, next to buildings, research, heroes and troops, and the might page shows how the five fit together.
You open the Raven Nest at Sanctuary level 7. The Raven screen has Stats, Raven Gear, Skill and Skin tabs. Raven gear opens later, at Sanctuary level 15, together with the Raven Workshop. The buildings page has the costs of both buildings.
Raven Skill Stars
The Raven casts Raven Fireworks. At level 1 it targets the 2 enemies with the highest HP and deals 1184% ATK as Physical DMG with a 13 second cooldown. The skill gains a star at levels 30, 50, 70, 90 and 110, and each star raises the damage and adds a debuff or extra damage.
| Stars | Raven level | Skill damage | New effect |
|---|---|---|---|
| 0 | 1 | 1184% ATK | None |
| 1 | 30 | 1190% ATK | Increases damage taken by affected targets by 12% for 5s |
| 2 | 50 | 1428% ATK | Deals 18% extra damage |
| 3 | 70 | 1598.4% ATK | Increases damage taken by affected targets by 15% for 5s |
| 4 | 90 | 1864.8% ATK | Extra damage increases to 36% |
| 5 | 110 | 1894.2% ATK | Increases damage taken by affected targets by 15% for 7s |
Raven Levels and Upgrade
Feeding Raven Fruit fills the progress bar of the current level. When the bar is full, the Raven levels up and its attributes rise. Below 80% progress, a feeding has a 50% chance to crit and double the progress it gives. Above 80% there are no crits.
Key levels work differently. Every 5th level up to 145, and every level from 150, uses a five phase Key Upgrade that costs Raven Essence as well as Fruit, and Essence steps never crit. The table shows the stats at each milestone and what it costs to finish that level and to reach it from level 1. Fruit totals are base values before crits.
| Level | Raven HP | Raven ATK | Raven DEF | Fruit to finish | Essence to finish | Fruit to reach | Essence to reach |
|---|---|---|---|---|---|---|---|
| 1 | 13,960 | 523 | 105 | 4,000 | None | 0 | 0 |
| 5 | 14,830 | 547 | 111 | 11,250 | 5 | 16,000 | 0 |
| 10 | 22,193 | 751 | 166 | 15,000 | 10 | 51,250 | 5 |
| 20 | 49,452 | 1,308 | 371 | 22,500 | 30 | 197,000 | 35 |
| 30 | 108,982 | 2,070 | 818 | 30,000 | 50 | 477,750 | 105 |
| 50 | 386,737 | 4,237 | 2,904 | 37,500 | 120 | 1,820,250 | 395 |
| 70 | 945,916 | 7,101 | 7,102 | 45,000 | 200 | 4,332,750 | 995 |
| 90 | 1,873,455 | 14,065 | 14,066 | 52,500 | 400 | 7,935,250 | 2,095 |
| 110 | 3,254,686 | 24,434 | 24,435 | 75,000 | 700 | 13,582,750 | 4,045 |
| 150 | 6,419,280 | 48,192 | 48,193 | 900,000 | 500 | 64,200,150 | 22,045 |
| 200 | 8,617,115 | 64,693 | 64,693 | 1,800,000 | 1,000 | 127,200,150 | 57,045 |
| 250 | 11,188,803 | 84,000 | 84,000 | - | - | 235,200,150 | 117,045 |
Reaching level 110 takes about 13,582,750 Fruit and 4,045 Essence. The whole climb to level 250 takes about 235,200,150 Fruit and 117,045 Essence. After level 145 every level becomes a key level. The Essence cost per level falls from 5,000 to 500, while the Fruit cost triples.
Raven Essence Sources
Raven Essence raises the level cap of the Raven. It is sold in shops one unit at a time, and each shop has its own purchase limit. One guide also counts 4 Essence per day from the second and third daily quest chests, and the Alliance Caravan and Crystal Cluster Valley rewards include Essence too. The shops page shows what else each shop sells.
| Shop | Currency | Price per Essence | Purchase limit |
|---|---|---|---|
| Thief Hunt shop | Lion Coins | 200 | 50 |
| VIP Shop | Diamonds | 398 | 50 |
| Honor Shop | Fame Medals | 800 | 100 |
| Expedition Shop | Expedition Medals | 300 | 30 |
| Alliance Shop | Alliance Coins | 990 | 10 |
| Sanctuary Shop | Copper Coins | 100,000 | 10 |
Raven Fruit Sources
Raven Fruit is the main fuel for leveling. It drops in stacks of 500, 1K, 10K and 100K. The Expedition Shop sells a 100K stack for 2,100 Expedition Medals, up to 25 times, which makes it the biggest single source.
World map Blights pay a first kill reward of Raven Fruit: 920 for a level 1 resource Blight, rising to 1,600 at level 30. One guide says this reward resets every day and that Falcon Quests and the Thief Hunt event also pay Fruit. The Falcon Tower page explains the quests.
What to Know First
This video shows the Raven screens and the order in which to upgrade them, which makes the tables above easier to read before you spend Fruit.
Raven Evolution Stages
Evolution is a second track that is separate from the Raven level. It raises Raven HP, ATK and DEF and unlocks the Epigraph Plans, with up to 900 evolve levels. You raise it with Raven Evolve Guide items, which give 10,000 or 1,000 Evolve EXP each, and with spare Epigraphs of lower ranks. UR Epigraphs cannot be used as material. The Alliance Shop sells the 10,000 EXP guide for 1,980 Alliance Coins, up to 5 times.
| Evolve level | Stage | Unlocks | Raven HP | Raven ATK | Raven DEF |
|---|---|---|---|---|---|
| 10 | Stage I | Unlock Epigraph system; Unlock Epigraph Plan 1 | 100,870 | 595 | 596 |
| 150 | Stage II | Unlock Epigraph Plan 2; Epigraph System Boost reaches +1 | 678,227 | 4,001 | 4,001 |
| 300 | Stage III | Unlock Epigraph Plan 3; Epigraph System Boost reaches +2 | 1,791,188 | 10,566 | 10,566 |
| 450 | Stage IV | Unlock Epigraph Plan 4; Epigraph System Boost reaches +3 | 3,211,318 | 18,943 | 18,943 |
| 600 | Stage V | Epigraph System Boost reaches +4 | 5,541,281 | 32,687 | 32,687 |
| 750 | Stage VI | Epigraph System Boost reaches +5 | 8,013,602 | 47,270 | 47,270 |
| 900 | Stage VII | Massive Stats boost, Raven Might can increase by over 2M from Lv.751-900 | 17,710,779 | 104,472 | 104,472 |
Evolve level 10 opens Epigraph Plan 1, and Plans 2, 3 and 4 follow at 150, 300 and 450. The Epigraph types, crafting and faction rules have their own page, the Epigraphs guide.
Raven Gear and Chests
Raven gear is a separate set from hero gear, so the gear page does not cover it. The Raven wears 6 pieces, three that boost the Raven and three that boost your heroes. Each piece runs from level 1 to 12, and the Fuse Multiple button turns spare duplicates into higher pieces. The table shows the base stat of each piece at levels 1, 7 and 12, and the extra bonuses that come at higher levels.
| Piece | Level 1 | Level 7 | Level 12 |
|---|---|---|---|
| Heart of Wisdom | 9,324 Raven HP | 1,351,647 Raven HP | 8,995,299 Raven HP, 5% Crit rate taken (reduced) |
| Feather of the Night | 4,662 Hero HP | 619,380 Hero HP | 4,997,388 Hero HP, 30% Hero HP |
| Sharp Beak | 35 Hero DEF | 4,450 Hero DEF | 35,731 Hero DEF, 30% Hero DEF |
| Tail of Wind | 75 Raven DEF | 9,750 Raven DEF | 64,315 Raven DEF, 10% Crit rate |
| Attacker's Claw | 60 Raven ATK | 9,700 Raven ATK | 64,316 Raven ATK, 20% Crit DMG |
| Eye of Perception | 30 Hero ATK, 0.25% Hero DMG dealt | 4,500 Hero ATK, 3.5% Hero DMG dealt | 35,731 Hero ATK, 15% Hero DMG dealt, 30% Hero ATK |
Pieces come from Raven Gear Chests. A Lv.N chest gives one random Lv.N piece, chests exist from Lv.1 to Lv.12, and Choice Chests let you pick the piece. The Raven Workshop makes Lv.1 chests on its own. The Expedition Shop sells 3 Lv.3 chests for 200 Expedition Medals each, the Thief Hunt shop sells 3 for 360 Lion Coins each, and the Alliance Shop sells 20 Lv.1 chests for 990 Alliance Coins each. Alliance Caravans also drop chests, and one guide adds Falcon Quests and Covert Ops. A Lv.7 chest is worth 810,000 points on Day 3 of Alliance Duel, so several guides save chests for that day.
Raven Set Bonuses
The game shows "Raven set not activated" until you equip the gear that belongs to a set. Two sets exist, the Night Raven Mask and the Raven Feather Cloak, and each has 12 levels. The Mask raises Raven HP, hero HP and hero DEF, the same stats as Heart of Wisdom, Feather of the Night and Sharp Beak. The Cloak raises Raven ATK, Raven DEF and hero ATK, the stats of Tail of Wind, Attacker's Claw and Eye of Perception. One guide says the three pieces beside a set must all reach level 7 before the set can reach level 7, so finish one side before you split your chests.
| Set | Level 1 | Level 4 | Level 8 | Level 12 |
|---|---|---|---|---|
| Night Raven Mask | 7,200 Raven HP, 4,000 Hero HP, 29 Hero DEF | 57,600 Raven HP, 32,000 Hero HP, 229 Hero DEF | 216,000 Raven HP, 120,000 Hero HP, 858 Hero DEF | 720,000 Raven HP, 400,000 Hero HP, 2,860 Hero DEF |
| Raven Feather Cloak | 52 Raven ATK, 29 Hero ATK, 52 Raven DEF | 412 Raven ATK, 229 Hero ATK, 412 Raven DEF | 1,545 Raven ATK, 858 Hero ATK, 1,545 Raven DEF | 5,150 Raven ATK, 2,860 Hero ATK, 5,150 Raven DEF |
Raven Workshop and Nest
The Raven Workshop opens at Sanctuary level 15 and has 30 levels. It produces Lv.1 Raven Gear Chests over time and stores 24 hours of output, so chests stop piling up if you skip a day. Every Workshop level shortens the time per chest. The four right columns show the Grain, Timber, Herb and time that each Workshop upgrade costs. The Raven Nest opens at Sanctuary level 7 and has a single level, because it is the screen where you manage the Raven and not a building you upgrade. Both sit in the Gear and Raven group on the buildings page.
| Workshop level | Time per chest | Chests per day | Storage | Grain | Timber | Herb | Build time |
|---|---|---|---|---|---|---|---|
| 1 | 4h 0m | 6 | 24 hours | 9 | 9 | 0 | 2s |
| 5 | 3h 52m | 6.21 | 24 hours | 6,761 | 6,761 | 0 | 8m |
| 10 | 3h 42m | 6.49 | 24 hours | 122.9K | 122.9K | 59,340 | 1h 28m |
| 15 | 3h 32m | 6.79 | 24 hours | 1.08M | 1.08M | 561.1K | 5h 33m |
| 20 | 3h 22m | 7.13 | 24 hours | 9.51M | 9.51M | 4.6M | 1d 5h 55m |
| 25 | 3h 12m | 7.5 | 24 hours | 50.02M | 50.02M | 23.86M | 5d 12h 46m |
| 30 | 3h 2m | 7.91 | 24 hours | 244.5M | 244.5M | 120.9M | 25d 15h 43m |
Raven Skins
Raven skins unlock automatically as the Raven level rises, and each skin from level 50 on gives a bonus. Forest Raven is the starting skin. Lunar Shadow is a separate event skin that gives Raven ATK +1,000 and Crit Rate +2%. The skins page lists city, march and chat skins too.
| Skin | Unlocks at | Bonus |
|---|---|---|
| Forest Raven | Raven level 1 | None |
| Oath's Eye | Raven level 50 | Raven ATK +5100 |
| Embers of War | Raven level 100 | All Hero ATK +5.5% |
| Shadow Sentinel | Raven level 150 | All Hero Skill damage +2.5% |
| Raven Guardian | Raven level 200 | All Hero damage taken -5.5% |
| Phantom Hunter | Raven level 250 | In PvP battles, enemy soldier casualties +5.5% |
Raven Epigraphs
Epigraphs are skill modules that you slot into Epigraph Plans. They buff the squad assigned to a plan, and the faction of the Epigraph must match the heroes in that squad. Plan 1 opens at evolve level 10, as the evolution table shows. Crafting, ranks, stars and the Epigraph Workshop are on the Epigraphs page.
Raven's Gratitude Quest
Raven's Gratitude is the game's name for the Raven arrival quest. The game describes it as "A companion from the sky" and says the Raven's firepower helps you eliminate the Blight. After the Raven arrives, it grows through the level, evolution and gear systems described above.
Raven Upgrade Order
The data above gives a simple order. Early on, Fruit does most of the work, and Essence matters at key levels.
- Build the Raven Nest at Sanctuary level 7 and finish the unlock treatment.
- Feed Fruit through the first levels and spend Essence at the key levels.
- Push the level to 30, 50, 70, 90 and 110 for the five skill stars, picking up the Oath's Eye and Embers of War skin bonuses at 50 and 100.
- Build the Raven Workshop at Sanctuary level 15, collect chests every day and fuse duplicates into one strong piece per slot.
- Raise the evolve level to 10 to open Epigraph Plan 1, then aim for 150, 300 and 450 for the next plans.
Frequently Asked Questions
What is the max Raven level?
The Raven levels up to 250. Levels 1 to 110 need 4,045 Raven Essence in total, and the full climb to 250 needs 117,045. Raven Evolution is a separate track that goes up to level 900 and opens the Epigraph Plans. The level table lists the cost of each step.
How do I get Raven Essence?
Raven Essence comes from shops, one unit per purchase. The Honor Shop allows 100 purchases for 800 Fame Medals each, the Thief Hunt shop 50 for 200 Lion Coins, and the Expedition Shop 30 for 300 Expedition Medals. The sources table has every shop.
Does the Raven affect all squads?
Yes. The Raven fights next to your five heroes, and part of its HP, ATK and DEF converts into hero stats in battle. Any upgrade you make to the Raven applies to every squad, so it is one of the most efficient places to put resources. Epigraph bonuses work per squad and depend on how many Epigraph Plans you have unlocked.
What does the Raven Workshop produce?
The Raven Workshop produces Lv.1 Raven Gear Chests over time. At level 1 it makes one chest every 4h 0m, and at level 30 one every 3h 2m. It stores 24 hours of output, so collect the chests at least once a day. The Workshop section has the full speed table.
How many pieces of Raven gear can I equip?
You can equip 6 pieces of Raven gear: Heart of Wisdom, Feather of the Night, Sharp Beak, Tail of Wind, Attacker's Claw and Eye of Perception. Each piece levels from 1 to 12. Two set bonuses, the Night Raven Mask and the Raven Feather Cloak, come on top of the pieces. The feature opens at Sanctuary level 15.
Which Raven skin is best?
The skins unlock by Raven level, so you cannot buy a better one early. Oath's Eye gives Raven ATK +5100 at level 50, and Embers of War gives all heroes ATK +5.5% at level 100. Raven Guardian at level 200 cuts hero damage taken by 5.5%. The Raven skins section lists all six, and the skins page covers the rest.
