The Spellbook: pages, runes and the mentor
How the Spellbook works in The Ember Depths 0.25: page picks at levels 4, 9, 14 and 18, runes that change a skill, the class mentor and mastery bonuses.
Your seven core skills stay exactly as they are. On top of them, from level 4 you build a Spellbook: extra skills, called pages, that you choose. Each page has runes that change how it plays, so the same page can power very different builds.
Page picks
- When. You pick a page at levels 4, 9, 14 and 18. Each pick offers up to 3 pages you don't own yet, and you take one.
- How many. A class uses only as many picks as it can always fill with at least two real choices, so a class with fewer pages has fewer picks. A pick you haven't made yet waits for you on the hero sheet's Spellbook tab.
- The mechanic. Your first page switches on your class's signature mechanic (the Classes Reborn page lists them all).
- No book for hirelings. Sellswords don't get a Spellbook; the pages are for your heroes.
Runes
- Every page has 2 or 3 runes, unlocking as the skill gains mastery ranks 2, 5 and 8.
- Only one rune is active per page. Choose it on the hero sheet's Spellbook tab.
- Runes change behaviour, not just numbers: a wider spiral, a burst where a hammer ends, a single boss-breaking blow, a heal for the whole party.
Page mastery
Page skills have no A/B mastery perks. Instead they gain a flat +30% power at mastery ranks 4 and 8, besides their runes.
The class mentor
- A page you passed over can be bought from your class mentor for 30 gold × your level squared: 480 gold at level 4, 12,000 at level 20.
- The mentor only sells while every pick still to come keeps at least two choices.
- Changing class (possible only up to level 5) forgets your pages and refunds what you paid the mentor; the confirm dialog says so.
