[DoH Question] How To Make Undamaged Items?

[Johnist]

If you mean the "Durability" of the recipe... that's just to show how many 'steps' that effect quality/completion you have left. It has nothing to do with the resulting item except that if it hits 0 your Synthesis fails.

At Level 15 in Goldsmith you learn 'Manipulation' which is cross-class and allows you (for 88 CP) to not lose Durability for the next 3 steps. If used early on, its better than 'Master's Mend' which restores 30 durability for 92.

And yes, the 'make many' Function is called Quick Synthesis and is an automated process.
