Last Asylum Plague Epigraphs
Epigraphs are Raven upgrades that buff the heroes of one squad in PvP and PvE. You craft them in the Epigraph Workshop from Epigraph Shards or open them from Epigraph Chests. The Workshop unlocks at Sanctuary level 5, SSR epigraphs need Workshop level 15 and UR epigraphs need level 20. Raven basics live on the Raven page, so this guide covers the Workshop, rarities, chests, stars, Epigraph Plans and the best picks.
Epigraph Workshop
The Epigraph Workshop is a single building that unlocks with the Sanctuary at level 5 and upgrades to level 30. It does not add stats by itself. Its level decides which epigraphs you can craft: level 15 for SSR and level 20 for UR. The system itself opens only after the Raven reaches Evolve level 10, so there is no rush to build the Workshop before that. The full upgrade costs 844,385,340 Grain, 844,385,340 Timber and 413,100,000 Herb at base values, before Construction Speed bonuses. Other buildings are listed on the buildings page.

Epigraph Rarities
Epigraphs come in four rarities, written with numerals in their names: I is R, II is SR, III is SSR and IV is UR. Each rarity has four epigraphs, one per type. UR and SSR epigraphs also come in Warrior, Ranger and Warlock versions, which gives 12 of each, while SR and R epigraphs work for every faction. That makes 32 epigraphs in total. A faction version buffs only the heroes of that faction, so match it to the squad you plan to use. The heroes page explains the factions.
| Rarity | Epigraphs | Workshop level | Shards per craft | Max star | Might per epigraph |
|---|---|---|---|---|---|
| UR (IV) | 12 | 20 | 800 UR Epigraph Shards | 6 | 120,000 to 600,000 |
| SSR (III) | 12 | 15 | 400 SSR Epigraph Shards (800 for Guard of Nature III) | 5 | 20,000 to 210,000 |
| SR (II) | 4 | Chests only | Not craftable | None | 8,000 |
| R (I) | 4 | Chests only | Not craftable | None | 4,000 |
Guard of Nature III for the Warrior faction is the one SSR entry in the craft list with no Workshop level requirement. The rest of the SSR list asks for level 15. UR epigraphs carry about six times the Might of SSR ones at their first star, and the gap stays wide at the top star, as the stars table shows.
Epigraph Video Guide
This video walks through the Raven and epigraph system, which helps you see how the Workshop, Raven Evolve levels and the squads connect before you commit shards.
How to Craft Epigraphs
- Upgrade the Sanctuary to level 5 and build the Epigraph Workshop.
- Evolve the Raven to level 10. This is Evolve Stage I, and it unlocks the epigraph system and Epigraph Plan 1. The Raven page covers evolving.
- Upgrade the Workshop to level 15 for SSR crafts or level 20 for UR crafts.
- Collect shards of the matching rarity. UR Epigraph Shards come with every epigraph chest, and SSR Epigraph Shards come from the 7-Day Epigraph Supply.
- Pick the faction and the type in the Workshop and pay the shards: 800 UR shards for a UR epigraph, 400 SSR shards for most SSR epigraphs.
- Equip the finished epigraph in an Epigraph Plan for the squad you want to buff.
Epigraph Types
Every rarity has the same four types: Initiative, Attack, Support and Defense. The table shows the Warrior versions. Ranger and Warlock versions have the same numbers for their own faction. Values grow with the star level, so the table lists the first and the last star. Raven's own skill, Raven Fireworks, hits the 2 enemies with the highest HP, which matters for Frenzied Flock IV below.
| Type | UR at star 0 | UR at star 6 | SSR at star 0 | SSR at star 5 |
|---|---|---|---|---|
| Initiative: Guard of Nature | 800K HP shield that absorbs 50% damage for 15s, then 5% less damage taken | 4.0M HP shield that absorbs 50% damage for 15s, then 15% less damage taken | If the faction has HP above 50%, all allies take 1% less damage | If the faction has HP above 50%, all allies take 6% less damage |
| Attack: Frenzied Flock | +2.5% ATK for 3s after a Raven skill, Raven skill targets +1 | +12% ATK for 3s after a Raven skill, Raven skill targets +3 | +1% ATK for 3s after a Raven skill | +4.5% ATK for 3s after a Raven skill |
| Support: Reversal Power | Top 3 ATK allies deal 3% more damage for 3s, enemies deal 5% less | Top 3 ATK allies deal 15% more damage for 3s, enemies deal 13% less | Top 3 ATK allies deal 2% more damage for 3s | Top 3 ATK allies deal 12% more damage for 3s |
| Defense: Protective Charm | +9% DEF for the faction, top 2 max HP allies get another +13.5% DEF | +27% DEF for the faction, top 2 max HP allies get another +40.5% DEF | +2.5% DEF for the faction until battle ends | +11.25% DEF for the faction until battle ends |
Frenzied Flock IV is the only epigraph that changes how many enemies the Raven skill hits. It adds 1 target at star 0, 2 targets from star 2 and 3 targets from star 5, so the skill can reach 5 enemies. SR and R epigraphs have one flat effect and no stars. Guard of Nature II lowers damage taken by 2% and Guard of Nature I by 1%, which is why they mostly serve as Raven Evolution material.
Epigraph Chests
An epigraph chest gives one random epigraph of its rarity or higher plus UR Epigraph Shards, so every chest moves you toward the next UR craft. The UR Epigraph Choice Chest lets you choose the epigraph. A UR craft costs 800 shards, which is 8 UR chests of shards alone, or 27 SSR chests.
| Chest | Possible rarity | UR shards | Chests for one UR craft |
|---|---|---|---|
| R Epigraph Chest | R/SR/SSR/UR | 1 | 800 |
| SR Epigraph Chest | SR/SSR/UR | 5 | 160 |
| SSR Epigraph Chest | SSR/UR | 30 | 27 |
| UR Epigraph Chest | UR | 100 | 8 |
| UR Epigraph Choice Chest | UR | 100 | 8 |
Chests are sold in several places, and the limits below are per shop. The shops page covers the full stock, and the VIP page explains the VIP Shop.
| Shop | Chest | Price | Limit |
|---|---|---|---|
| Expedition Shop | R Epigraph Chest | 400 Expedition Medals | 20 |
| Expedition Shop | SSR Epigraph Chest | 11,000 Expedition Medals | 1 |
| Alliance Shop | SR Epigraph Chest | 3,980 Alliance Coins | 5 |
| Honor Shop | UR Epigraph Chest | 50,000 Fame Medals | 1 |
| VIP Shop | SR Epigraph Chest | 60% off offer | 10 |
| Thief Hunt Shop | SR Epigraph Chest | 120 Lion Coins | 3 |
| Thief Hunt Shop | SSR Epigraph Chest | 400 Lion Coins | 1 |
| Strange Bazaar | SSR Epigraph Chest | 30 Strange Coins | 20 |
| Strange Bazaar | UR Epigraph Chest | 200 Strange Coins | 30 |
| Strange Bazaar | UR Epigraph Choice Chest | 375 Strange Coins | 5 |
| Blades Out Shop | UR Epigraph Chest | 55 Stone Blades | 10 |
Alliance Duel chests can also drop UR epigraphs, and the Alliance Duel page lists the rest of its rewards. The Epigraph Pass has three tiers, a free one plus an Epic and a Mythic pass, and you level it with daily quests. The Epigraph Bond event pays rewards when your epigraphs reach set Might values.
7-Day Epigraph Supply
This event runs for 8 days and unlocks one pack per day for the first 7 days. Unclaimed packs are lost after it ends, so log in daily. It is the main source of SSR Epigraph Shards: days 1 and 3 give 870 SSR shards, enough for two 400-shard crafts or one 800-shard craft.
| Day | Reward |
|---|---|
| 1 | 420 x SSR Epigraph Shard |
| 2 | 6 x Raven Evolve Guide (1,000 EXP) |
| 3 | 450 x SSR Epigraph Shard |
| 4 | 6 x Raven Evolve Guide (1,000 EXP) |
| 5 | 6 x Raven Evolve Guide (1,000 EXP) |
| 6 | 3 x Raven Evolve Guide (10,000 EXP) |
| 7 | SSR Epigraph Chest |
Epigraph Stars
Stars raise the effect and the Might of an epigraph, and each new star needs more copies of the same epigraph than the last. The copies column counts the epigraph itself plus every copy spent so far. A UR epigraph reaches star 6 with 29 copies in total. An SSR epigraph reaches star 5 with 19.
| Star | Total copies | UR Might | SSR Might |
|---|---|---|---|
| 0 | 1 | 120,000 | 20,000 |
| 1 | 2 | 160,000 | 30,000 |
| 2 | 4 | 240,000 | 60,000 |
| 3 | 7 | 280,000 | 75,000 |
| 4 | 12 | 340,000 | 110,000 |
| 5 | 19 | 500,000 | 210,000 |
| 6 | 29 | 600,000 | - |
The last star is the most expensive: star 6 on a UR epigraph needs 10 more copies for 100,000 extra Might. Spare SSR epigraphs have another use. At star 0 an SSR epigraph is worth 20,000 to 40,000 Raven Evolve EXP, while one Raven Evolve Guide grants 10,000, so decide whether a spare is star material or evolve material. See the might page for other ways to raise total power.
Epigraph Plans
An Epigraph Plan is a set of epigraph slots that you assign to one squad. With a single plan, the buffs apply to only one squad of your choice, and each extra plan covers another squad. Plans open with Raven Evolve stages, listed below. The same stages also raise the Epigraph System Boost.
| Raven Evolve level | Stage | Epigraph unlock |
|---|---|---|
| 10 | Stage I | Unlock Epigraph system; Unlock Epigraph Plan 1 |
| 150 | Stage II | Unlock Epigraph Plan 2; Epigraph System Boost reaches +1 |
| 300 | Stage III | Unlock Epigraph Plan 3; Epigraph System Boost reaches +2 |
| 450 | Stage IV | Unlock Epigraph Plan 4; Epigraph System Boost reaches +3 |
| 600 | Stage V | Epigraph System Boost reaches +4 |
| 750 | Stage VI | Epigraph System Boost reaches +5 |
Plan 1 is available as soon as the system opens, and plans 2 to 4 follow at levels 150, 300 and 450. Finish a full set for your first plan before you spread shards across the others. Your squads page shows how to build the squads these plans will buff.
Best Epigraphs
No single epigraph wins for every account, but a few rules hold up on the numbers and in the guides.
- Match the faction. A Warrior epigraph buffs only Warrior heroes, so Ranger or Warlock versions are wasted on a Warrior squad. Pick your squad on the best team list first.
- Prefer UR. A UR epigraph starts at 120,000 Might, and a maxed SSR reaches 210,000, so even a fresh UR beats a fully starred SSR.
- Start with Frenzied Flock IV when you can. It is the only epigraph that adds Raven skill targets, up to +3.
- Give the best epigraphs to the main squad, the next best to the second squad, and the leftovers to the rest, especially for PvP.
- Finish one full set of four before you start a second faction.
Gear and the Raven grow side by side, so check the gear page for the hero side and the upgrade guide for where epigraphs fit in the overall order.
Frequently Asked Questions
How do I get epigraphs in Last Asylum?
You get epigraphs from two routes. Craft them in the Epigraph Workshop with Epigraph Shards, or open Epigraph Chests from the Expedition, Alliance, Honor, VIP and Thief Hunt shops and from Alliance Duel. The system itself opens at Raven Evolve level 10. Details for each route are in Epigraph Chests.
What Epigraph Workshop level do I need for UR epigraphs?
UR epigraphs need Epigraph Workshop level 20 and 800 UR Epigraph Shards each. SSR epigraphs need level 15 and 400 SSR Epigraph Shards, or 800 for Guard of Nature III. At base speed levels 1 to 20 take 4d 12h 6m. The level table lists every cost.
How many Epigraph Plans can I unlock?
You can unlock four Epigraph Plans, and each plan covers one squad. Plan 1 opens at Raven Evolve level 10, Plan 2 at level 150, Plan 3 at level 300 and Plan 4 at level 450. With only one plan, the buffs apply to one squad of your choice. See the Raven page for how evolving works.
Which epigraphs should I craft first?
Craft epigraphs that match the faction of your main squad, and pick UR before SSR when you can afford it. Frenzied Flock IV is the one epigraph that adds targets to the Raven skill, up to +3. A Warrior epigraph does nothing for a Ranger squad, so check your best team first.
Can I use spare epigraphs for Raven Evolution?
Yes for R, SR and SSR epigraphs, but not for UR. A spare SSR epigraph gives 20,000 to 40,000 evolve EXP at star 0, and a higher star level gives more. UR epigraphs cannot be used as Raven Evolution material, so keep them for your squads.
How many copies does a UR epigraph need for max stars?
A UR epigraph reaches star 6 with 29 copies of the same epigraph in total, and an SSR epigraph reaches star 5 with 19. The stars table shows the running total for every star and the Might each star adds.
