WHAT IS TREE BOOK IN RAID SHADOW LEGENDS

In RAID: Shadow Legends , there is no item officially called “Tree Book.” The phrase likely comes from one of three common mix‑ups players make:

  1. Skill Tomes (Skill Books) – the actual “books” used to upgrade champion skills.
  2. Mastery Trees – the three branching “trees” (Offense, Defense, Support) that look like skill trees, not books.
  3. Tree of Genesis guides – some content creators talk about “Tree of Genesis” and “Gold Book / Blue Book” in other games or in RAID event contexts, which can get misheard as “Tree Book.”

Below is what each of those actually is, so you can pin down what you meant.

1. Skill Tomes = the “books” in RAID

When players say “book” in RAID, they almost always mean Skill Tomes :

  • Common Tome – upgrades common skills
  • Uncommon Tome – upgrades uncommon skills
  • Rare Tome – upgrades rare skills
  • Epic Tome – upgrades epic skills
  • Legendary Tome – upgrades legendary skills

These are used in the Champion > Skills screen to level up a specific skill slot. They’re widely considered one of the most valuable resources in the game, especially Legendary Tomes , because they’re rare and you only get a few from daily clan boss chests, events, and some promos.

Typical sources:

  • Clan Boss chests (Unmimated/Nightmare) – main steady source of epic & legendary tomes
  • Events & login rewards
  • Promo codes – some give “1 Epic Book” or similar as a one‑time reward
  • Dungeon drops / faction wars / campaign (lower tiers mostly)

If someone says “don’t waste your books,” they mean: don’t skill up low‑priority champions with rare/epic/legendary tomes.

2. Mastery Trees – the “tree” part

RAID has a Mastery system with three Mastery Trees :

  • Offense Tree – damage, crit, ignore res, etc.
  • Defense Tree – HP, def, shield, damage reduction, etc.
  • Support Tree – speed, aura, cooldown reduction, healing buff, etc.

Each champion has a Mastery screen where you allocate points into nodes across these three trees to shape their build. Guides often say things like “best mastery tree for X” or “support tree build,” which can get misremembered as “tree book.”

Key points:

  • You unlock masteries by leveling champions and spending Mastery points.
  • You can reset and reassign them freely (no cost).
  • Different champions need different tree paths depending on their role (damage, support, tank, etc.).

So:

  • “Book” = Skill Tomes
  • “Tree” = Mastery Trees
    There is no single item called “Tree Book.”

3. “Tree of Genesis” + “Gold/Blue Book” confusion

Some recent RAID content (especially from YouTubers who also cover other games) talks about:

  • “Tree of Genesis” – usually an event / research / progression system in other gacha titles or special RAID events.
  • “Gold Book” / “Blue Book” – terms used in those guides for specific research tracks or currencies, not standard RAID items.

If you saw a title like “2026 GUIDE for TREE OF GENESIS – RESEARCH (The Gold Book)” near RAID content, your brain might merge it into “Tree Book in RAID Shadow Legends.” In that case:

  • That “Gold Book / Blue Book” terminology is not part of core RAID mechanics like skill tomes or masteries.
  • It’s tied to a specific event or external game and doesn’t represent a permanent RAID item called “Tree Book.”

Quick TL;DR

  • There is no “Tree Book” item in RAID: Shadow Legends.
  • Players usually mean:
    • Skill Tomes (Skill Books) – used to upgrade champion skills.
* **Mastery Trees** – the three specialization trees (Offense/Defense/Support).

* Or they’re mixing RAID with **“Tree of Genesis” + “Gold/Blue Book”** guides from events/other games.

If you tell me where you saw “Tree Book” (Discord, YouTube title, friend’s message, etc.), I can pinpoint exactly which of these they were talking about and how to use it. TL;DR: “Tree Book” isn’t a real RAID item; it’s almost certainly a mix‑up of Skill Tomes (books) and Mastery Trees , or a reference to Tree of Genesis / Gold-Book/Blue-Book event guides, not a standalone in‑game object.
