How input of rare mats into unfinished item works?

[Wilczan 2,048]

Hello

 

Got unfinished wagon. Put rare small wheel axle into it and luckily wagon became rare (still unfinished).

 

Thing is, I still have some rare parts for it (planks, shafts, nails). If I try to put more rare parts in it, is there a chance that it could became supreme? Or this is only possible if I continue with supreme parts?

 

Couse do not know if I should try to make another one rare.

From what i know, if it's already rare, using rare mats or normal mats in trying to get a supreme has the same chances, since at this point you are not relying on the rarity transfer chance (1%?), but on the rarity window.

Though so, thanks for confirmation.

Yep. Attaching a rare part would only give a chance to make it rare, not supreme.

 

It's not a 1% chance, though. When you attach a rare+ part (or get a rare+ moment of inspiration), the chance to transfer rarity to the item is 1 in <number of total parts the item requires>. So if a forge requires 22 parts, a supreme brick has a 1 in 22 chance of making it supreme.

 

Due to a semi-recent bugfix, this is also how it works when starting an unfinished item, not just when attaching.
