Skill Growth Books are the key resources that you need to enhance your character’s Active and Passive skills in Throne and Liberty. It’s a core part of your endgame grind in the MMO and you will not be able to min-max your favorite weapon combinations if you are not leveling your skills.
However, as an Active or Passive skill grows more powerful, the number and rarity of the Skill Growth Book required goes up. So if you want to have an easier time in the late-game dungeons you will need to know everything you can about the best ways to get more of this resource.
Best ways to farm Skill Growth Books in Throne and Liberty

Here are some of the best ways of farming Skill Growth Books in Throne and Liberty:
1) Complete main story missions
The main story missions are some of the best sources of upgrade materials in Throne and Liberty. By making your way through the various chapters you will be able to farm up a lot of Skill Growth Points.
In the early levels, you will get the books of the uncommon rarity which will soon turn into rare and epic once you reach the later levels.
2) Complete Codex entries
Completing certain entries in the Codex book will also reward you with both Active and passive Skill Growth Books. So make sure you are checking out the Codex often from the in-game menu screen.
3) Craft Skill Growth Books
Crafting is another great way of acquiring Skill Growth Books in Throne and Liberty. You will be able to make them by talking to the Skills Researcher of the major town that you are in.
To craft the uncommon books, you will need Parchment as well as Marind Ore, but for higher rarities, you will need paper along with an ore of a matching rarity. Parchment is something that you can farm from enemies, while Marind Ore is mined and also obtained as a reward for missions.
4) Complete Exploration Quests
Each region has a set of Exploration Quests that you will be able to complete. These are also unique to the region that you are in and will usually involve exploring the place, killing enemies, and taking part in Dynamic Events.
These are pretty easy to complete and don’t take long to round out. So make sure you are completing each of them in every region to get your hands on as many Skill Growth Books as possible.

5) Purchase them from the in-game shop
You will be able to use Ornate Coins to purchase Skill Growth Books from the Throne and Liberty in-game shop. You will be able to spend 5 and 10 Ornate Coins to get one Rare and one Epic Growth Book respectively.
Ornate Coins are a finite resource so use them sparingly. They are also used to buy Amitoi like the Lanlan Thwump.
6) Dismantle higher-tier Skill Growth Books for lower-tier ones
If you have a Precious purple Skill Growth Book you will be able to dismantle it for 10 Rare Skill Growth Books. While doing this is not something that we recommend, it can come in handy if you are looking to use Ornate Coins.
For 10 Ornate Coins you get 1 Precious Skill Growth Book, and dismantling it gives 10 Rare Skill Growth Books which are collectively worth 10 Ornate Coins. So if you need the blue rarity books, this is one trick that you can try as long as you have Ornate Coins to spare.
