I found a big big thing regarding crafting.
Okay so I was toying around with a modified save file experimenting stuff near the Anvil, Furnace, and Whetstone above the empty house in Cyseal.
Crafting quality is TIED to the characters level as well as crafting / smithing skill!
I've tested this with Two Branches.
A level 1 character combining two branches will make a level 1 Elemental Staff with appropriate stats you'd expect a level 1 item to have.
Where as a Level 14 character will likewise create a level 14 staff.
Also interesting information regarding stat caps.
The max attribute for Strength, Dexterity, Constitution, Speed, Intelligence, etc is 15.
Skills like Man-at-Arms, Geomancy, Hydrosophist and so forth max at 5 (However equipment with a + bonus to a skill WILL raise it beyond the cap of 5)
I've have not went too far with this because I just wanted to experiment, I have no intentions to play the game breaking the system. This is for a more educational purpose.
Naturally raising a skill from 1 to it's max of 5, requires a total of 15 skill points to master one skill (1+2+3+4+5 = 15)
The interesting thing is how skill points are given per level.
Skill point distribution is as follows
Levels 1 to 5 = 1 point per level
Levels 6 to 10 = 2 points per level
Levels 11 to 20 (soft cap) = 3 points per level
That's a total of 44 Skill points so you could barely max out 3 skills total.
Now as for Attributes and Talents
Attribute points (ie. stats)
You start with 5 and will gain 1 point every time you level up to an even number.
At level 20 you'll have allocated 15 in total.
Talent points
You start with 2 and will gain 1 extra talent every level-up that's a multiple of 3.
At level 20 you'll have 8 talents in total.
With this information. Someone with the knowledge can make a character planner / calculator.
Hope this information is useful to you
