Once you reach the desert island oasis, enhance a Ritual Tome by using Mela’s dedicated tome-upgrade shop with the tome and Asterine/Asterine Gems; if your version shows tome tiers as recipes, the same upgrade may appear as crafting the next-tier tome instead.
Ritual Tome enhancement is for players who want to keep using a favorite tome after enemy levels start outpacing it. The clearest route opens after enough main-story progress to reach the desert island and its Oasis, but some builds may present the same upgrade as a next-tier crafting recipe instead of a shop option.
When Ritual Tome enhancement becomes available

Enhancing a Ritual Tome raises the tome’s level and improves its damage, so an early favorite does not have to be thrown away just because stronger enemies start showing up. It is still an item upgrade, not a passive character upgrade, so the tome itself is what needs to be brought forward.

Requirements for a Ritual Tome upgrade
| Requirement | Why it matters | Confirmed detail | Caveat |
|---|---|---|---|
| Chosen Ritual Tome | The upgrade applies to the tome item itself. | Early-game tomes can reportedly be enhanced later. | Do not discard lower-tier tomes you may want to upgrade. |
| Asterine/Asterine Gem | This is the known enhancement material. | Stampede II uses 1x Asterine Gem. | Exact gem counts for every tome are not confirmed. |
| Desert Island and Oasis access | Mela’s tome-upgrade shop is found beside the Oasis. | The route opens after main-story progress to the desert island. | No exact quest name is confirmed here. |
| Crafting fallback | Some versions may list upgrades as next-tier recipes. | Stampede II consumes Stampede I as an ingredient. | The exact workstation for every tome is not fully verified. |
Before the upgrade will work, you need access to the Oasis, the Ritual Tome you want to improve, and the gem material tied to the next tier. The material name is not perfectly consistent yet: item records use Asterine Gem, while the upgrade route also refers to Asterine gems.
Keep every Rank I Ritual Tome you plan to upgrade; at least one Rank II recipe consumes the lower-tier tome as an ingredient.
Mela’s shop versus next-tier crafting
For this walkthrough, the main route is Mela’s tome-upgrade shop beside the Oasis. Reach the desert island, follow the quest marker to the Oasis, open the shop, pick the tome, spend the gem material, and confirm the enhancement.
The wrinkle is that some listed tome upgrades are framed as crafting the next-tier tome. In that format, “enhancing” a tome means using the lower-tier version as an ingredient, such as Stampede I becoming part of the Stampede II recipe.
Known Ritual Tome upgrade examples
| Tome or upgrade | Known input | Extra material | Evidence status |
|---|---|---|---|
| Ritual Tome: Stampede II | Ritual Tome: Stampede I | 1x Asterine Gem | Clearest confirmed recipe example. |
| Ritual Tome: Possession II | Ritual Tome: Possession I | Asterine Gem | Upgrade path is listed, but exact quantity is not firm. |
| Ritual Tome: Luxstorm 1 | Not confirmed | Not confirmed | Known tome/build item name only. |
| Ritual Tome: Crystal Orb 1 | Not confirmed | Not confirmed | Known tome/build item name only. |
The available recipe data does not cover every Ritual Tome, so do not treat this as a full upgrade list. What is clear is the pattern: at least some higher-tier tomes use the lower-tier tome plus Asterine Gem.
One base example is Ritual Tome: Possession I, which is listed with ritual materials such as 5x Simple Ritual Candle, 3x Shimmering Ink, and 1x Etherit. That supports the idea that Rank I tomes can be crafted first, then later used as upgrade inputs.
Common Ritual Tome upgrade mistakes

The easiest mistake is looking for the upgrade too early. If you have not reached the desert island and the Oasis through main-story progress, Mela’s tome-upgrade shop route is not the right place to spend time yet.
Another common mix-up is treating tome enhancement like a Luminary skill upgrade. Luminary progress can matter for broader crafting progression, but the damage improvement here is attached to the Ritual Tome item, not just your character sheet.
Be careful with crafting stations too. The Witchcraft Circle is tied to some witchcraft items, but current tome-upgrade records point players toward either Mela’s Oasis shop or next-tier recipes, with the Workbench appearing as the likely fallback for recipe-based tome upgrades.
Finally, avoid planning around exact multipliers, cast-time changes, mana values, coin fees, timers, or fixed gem farming routes. Those details are not confirmed, and Asterine/Asterine Gem farming is still not pinned down well enough to give a reliable route.
Frequently Asked Questions
Can early-game Ritual Tomes still be enhanced later?
Yes. Early-game Ritual Tomes can reportedly be upgraded once you reach the desert island Oasis route, letting a favorite tome keep scaling instead of being replaced immediately.
Where is the Ritual Tome upgrade shop?
The tome-upgrade shop is beside the Oasis on the desert island. Follow the main quest marker after reaching the island until you arrive at the Oasis landmark.
Do I enhance tomes at Mela’s shop or craft them at the Workbench?
Use Mela’s Oasis tome-upgrade shop as the main route. If your version does not show that option, check the Workbench or your crafting list for the next-tier tome recipe.
What is the Asterine or Asterine Gem used for?
Asterine Gem, also referred to as Asterine gems, is the known material used for Ritual Tome enhancement. The clearest example is Stampede II, which requires 1x Asterine Gem plus Stampede I.
Should I keep Rank I tomes?
Yes. Keep any Rank I Ritual Tome you may want to upgrade, because at least one Rank II recipe consumes the lower-tier tome as an ingredient.
More questions⤵
Are exact damage, mana, and scaling values known?
No. Enhancement is reported to raise the tome’s level and improve damage, but exact damage multipliers, mana costs, cast times, and tier scaling values are not confirmed.
Where can I farm Asterine or Asterine Gems?
A reliable Asterine/Asterine Gem farming route is not confirmed yet. For now, save any gems you find and spend them only on tome upgrades you actually plan to use.
