Raven epigraphs: stars, crafting and start

🗓 Updated: 2026-10-12

Data verified against the game client (v1.0.87, source: wiki-last-asylum.com).

Raven epigraphs slot into the raven blueprint and strengthen its skill, and through the skill the whole squad. There are 32 of them: four skill types across four ranks, with the higher ranks existing in three faction variants. They are built from fragments, and the first blueprint slot opens only at raven evolution level ten.

Stars and copies

Each next star needs more copies of the same epigraph: one, two, three, five and seven. That comes to 19 copies for five stars, eighteen of them consumed and one kept as the base.

It is easy to be off by a whole row here, because the star table holds an unused row for the final star: a naive count gives twenty-eight copies instead of 19.

Crafting

A top-rank epigraph costs 800 UR fragments and needs the Epigraph Workshop at level 20; there are twelve of those. The rank below is built from SSR fragments: nine cost 400 each and three cost 800. Fragments do not carry between ranks, so the right rank has to be saved from the start.

The seven-day epigraph event shows the scale: it hands out 870 SSR fragments over a week of logins, enough for two cheap epigraphs or one expensive one. It gives no UR fragments at all.

Where to start

Below raven evolution level ten epigraphs are unavailable, and the first blueprint slot opens together with that level at a modest cost. After that, the epigraphs to collect first are the ones that add targets to the raven’s skill: three of the thirty-two do that, one per faction, and they change the mechanic itself rather than percentages. The other twenty-nine grant percentages to allied attack, defense and damage.

DTF Field Guide: Chests, Workshop, Purple vs Gold, Quick Add

Practical supplement from the DTF epigraph guide. Rule zero: decide your main squad first. Epigraphs are faction-bound and the second plan opens only at Raven evolution 150 (third at 300), so every fragment spent on a side faction is a fragment missing from the set that fights today.

Where the system starts. The Nest carries its own Raven development track, and evolution level 10 opens the epigraph system with the first plan. Early levels can be pushed with the Raven development manual from the Alliance shop; after that, epigraphs and their fragments feed the Raven’s growth.

Chests. The main source is chests in green, blue, purple and gold — but chest color does not guarantee the item inside. Cheap chests can still drop a good epigraph, just at lower odds; purple and gold chests skew toward purple and gold items, or fragments toward a future craft. Sources: event rewards, Alliance shop, Expedition, VIP shop (prices are steep — never buy a chest just because it sits on the shelf).

Hold chests for the right Alliance Duel day (Monday): opening epigraph chests then scores extra points — the same resource does double duty for the Raven and the weekly event.

What to do with drops. Green and blue epigraphs are Raven food — feed them into Raven development with little regret. Purple epigraphs can serve in the main set for months when no gold equivalent exists; keep purple fragments too until the first set is assembled, since they craft missing pieces and raise stars on equipped items. Once the main squad is fully gold, spare purple fragments can go to the Raven freely.

Gold is never feedstock. Even an off-faction gold waits: today it looks useless, but when the next plan opens it may already cover half of the following set. A concrete case from the guide: Warriors main, gold Sorcerer drop, third plan nowhere near — keep it. In a few months those two Sorcerers can become the core of a third squad, and the kept piece suddenly saves 800 fragments.

The Workshop. Chests alone would make the system a lottery, so needed epigraphs are crafted from fragments, split across three factions: Warriors, Rangers, Sorcerers. Before every craft ask one question: does this piece strengthen my main squad right now? “Someday useful” is not a yes. Push the Workshop toward level 20 to work with gold normally — it is not among the most painful buildings in cost or time. Crafting prices vary: some purple pieces cost 400 fragments, dearer ones 800; gold costs 800. Always check the price tag, not just the icon.

First squad first. At evolution 10 you get plan one; plan two waits until 150, plan three until 300 — and 300 is not “tomorrow.” One finished set beats three half-collections sitting in inventory. Slot positions inside a plan are fixed by the game (e.g. Nature Guard, Frenzy Flock, Protective Charm, Reversal Power) — each type has its place, which at least prevents building a Frankenstein of incompatible effects. Faction icons tell them apart at a glance: sword for Warriors, arrow for Rangers, magic symbol for Sorcerers.

Should you invest in purple? Yes — an empty slot gives nothing and a purple gives a working bonus until the gold analog appears. But do not chase a perfect purple at any cost: later the price per star climbs, and the gold version ends up clearly stronger even without heavy investment. Two measured examples for Warriors:

• Protective Charm: purple III gives all allied Warriors 9.5% + 1% = 10.5% DEF for the battle; gold IV gives 9% + 2.4% = 11.4% DEF to all allied Warriors plus 13.5% + 4% = 17.5% DEF to the two allies with the highest HP. The gap is 0.9 points on the main line and a whole extra effect on top.
• Attack epigraph: purple gives the three highest-ATK Warriors +3% damage for 3 seconds after the Raven skill; gold gives +4.3% damage and enemies deal 6.2% less damage over the same 3 seconds.

So: equip purple, upgrade cheaply (especially when the next star is cheap), but bank rare fragments toward gold. When the gold analog arrives, switch almost always — even over an invested purple. No purple is worth draining the UR fund for a marginal last star.

Stars. Raising stars is a separate operation from crafting: it needs extra copies of the exact same epigraph or its fragments, with no single fixed price (one shown case asked 1,200 fragments or three identical epigraphs). The 400/800 fragment numbers in the Workshop are crafting prices for a new piece, not star prices. Before an expensive star-up, open the Preview tab and read what the next star actually adds — sometimes it is worth it, sometimes the fragments help another first-squad piece more.

Quick Add — useful, but verify. The button auto-fills green and blue items into Raven development, with a separate toggle for purple fragments — leave that toggle off until the main set is assembled. The system is decent at sparing future-faction or already-invested pieces, but still eyeball the list before confirming: remembering where a good purple went takes longer than the check. If the inventory feels short, audit green and blue stockpiles first — the “shortage” often disappears.

Recovering old investments. Star reset exists for leveled epigraphs: it returns the copies spent on stars (11 copies back in the shown case) for redistribution — most useful when a gold piece replaces a purple or the squad changes. Quirk worth knowing: feeding an old leveled epigraph to the Raven directly yields the same development XP as resetting it first, so reset is for redistributing copies, not for a hidden XP bonus.

Two UI traps. Epigraphs cannot be swapped while the squad’s troops are outside the fortress — marching squads (e.g. out gathering) lock their epigraph settings, so recall troops home first. And after a big swap, refresh saved lineups in modes that remember squads separately (notably Canyon Conquest), or you fight a week on the old saved version.

From-zero order. Raven to evolution 10 and open plan one; pick one faction for the main squad and assemble its full set; slot purples into empty places without over-investing; push the Workshop toward gold in parallel; feed green/blue to the Raven, purple only after confirming the first set does not need it; stockpile other-faction gold for plan two at 150. Recheck saved squads after every major upgrade.
