Describe your suggestion

So i think each of the individual scrolls should have their own quest that is just a separate area
The 3 efficiency scrolls should reward
Hammer Efficiency - Chthonic extractor
Cut Efficiency - Stonecutter
Axe Efficiency - Earth piercer

In the quest description the village it can be obtained from aswell as the % or chance of it working would be nice (im not sure the exact number)

Something like Hammer Efficiency is a scroll that can be obtained from Weaponsmiths, tool smiths, masons, librarians and armorers. When placed within a 5x5 area of the workbench it causes hammer crafting to use X less materials.
This sentence could effectively be reused for all efficacies and expertise, where expertise would just say how much of a boost they provide if that can be found.

The expertise should provide a reward of
Metal - Combustion Chamber
Wood - Forged Workbench + Forge Hammer
Gemstone - 2x Transfer Unit, 2x Core extractor and 6x core extractor pipe
Skin - Lubricant Dispenser
Scale - Lubricant Dispenser
Fibre - Planar Stabilizer
Bone - 2x thermal cells
Stone - Combustion Chamber
Fabric - Planar Stabilizer

This would allow an alternative and potentially earlier way to obtain this aside from crafting or finding them.

For the schematics i think the description should roughly be what they do ie howling blade makes the sword emit protective wind, throwing knife allows it to be thrown and sturdy guard gives more durability. It should also mention they can be found in dungeons, with sturdy guards description mentioning librarians can also sell it.

As for what they give i believe a weapon using that specific part but being a tier 4 or 5 material would be good. These schematics can easily be found once you enter stone towers which can be done with iron or stone tools so giving a weapon slightly higher than currently makeable (that would be able to be repaired) seems like a decent reward if done early.

Why would you like this added/changed?

The current tetra questline feels underwelming for any section that isnt the hammer progression.
The tools section feels very bland and uninspired and there are no hints to all the scrolls present in tetra that can help make very good tools. As such i believe some quests that offer helpful but not overpowered rewards centered around those scrolls would be beneficial both to playing and to making players aware those scrolls exist

Sounds like a good idea. Iirc when we made the Tetra questline, scrolls weren't a thing. In fact, I didn't know they existed until now 😅 Would you be comfortable with making these additions and submitting them in a PR?

I would be happy to if i could but truthfully i have no real idea how to properly use github or make edits to the E6 quests.

A different thing i didnt mention in this post is that additional gilding 1-5 scrolls from nether fortresses and art of war scrolls 1-8 from bastions that are part of tetra crafting

Fair enough 👍
