Demonic Spellbook is a Mythic material in Anime Adventures, the Roblox anime tower defense game. You need it for one evolution and one relic craft, and there is only one stage that hands it out.
Quick answer: Clear The Demon Leader to obtain the Demonic Spellbook; this stage is unlocked by a Demon Leader’s Portal. The portal has a 20% chance to drop on each clear of Fabled Kingdom Legend Stages 1-3, or you can get it from the Sunshine Demon in Infinite Mode.
Demonic Spellbook item details
The item sits in the Materials group at Mythic rarity. Its description reads “+Required to evolve a special unit…”, and its source line says “Obtained from Fabled Kingdom Portals.” That portal is the Demon Leader’s Portal, also a Mythic item, described in game as “+Use to open a special portal…”. Each portal gives you 3 tries. Everything here reflects Anime Adventures as of Update 21.

There are two places to farm the portal, both in Fabled Kingdom. The Legend Stages unlock in a chain, starting after you finish Fabled Kingdom Act 6.
| Source | Unlocks after | Portal drop |
|---|---|---|
| Fabled Kingdom Legend Stage 1 | Fabled Kingdom Act 6 | 20% per clear |
| Fabled Kingdom Legend Stage 2 | Legend Stage 1 | 20% per clear |
| Fabled Kingdom Legend Stage 3 | Legend Stage 2 | 20% per clear |
| Sunshine Demon (Infinite Mode) | Fabled Kingdom Infinite Mode | On defeat |
Each Legend Stage card shows the “20%” chance right on it. The Sunshine Demon is a secret enemy, so it does not turn up in every Infinite Mode run. When it does and you take it down, it drops a Demon Leader’s Portal.
Push all the way through Legend Stage 3 early. You need it cleared before the portal will open at all, so farming portals there covers both jobs at once.
How to get Demonic Spellbook from The Demon Leader

A successful clear pays out 1 Demonic Spellbook and 1 Sunshine Essence, both on every clear. Sunshine Essence carries the description “+Give this to your Hubris (Day)!” If both items show up in your rewards, the run counted.
What Demonic Spellbook is used for
| Use | Spellbooks | Rest of the recipe |
|---|---|---|
| Evolve Infinity Mage (Secret) into Infinity Mage (Endless) | 10 | Star Fruit x12, Star Fruit (Blue) x4, (Red) x3, (Pink) x3, (Rainbow) x1, 5,000 takedowns |
| Craft the Mirrorblade relic | 5 | 10 Relic Shards |
Mirrorblade is crafted at the Golden King under “Craft Relics”. Since each clear of The Demon Leader gives exactly one spellbook, the Infinity Mage evolution takes 10 clears and Mirrorblade takes 5.
