The Carnival - A Guide to Pets

[malawiglenn]

Any guides on the celestial smiths and/or any other special forms of crafting?

Pretty high up in the Guides section of the forum

Сraftsmen of Cairn

There are already resources with description of smiths in GD like Wiki or topics on forums. However, to my best knowledge, no one contains the complete information on them. The guide is intended to provide all valuable data on smiths to be used by new and experienced players. You will find here information on their location, unique talents and services. Note: Keep in mind that relics won’t get smith crafting bonus. Instead relics have their own bonus called “completion bonus”. To find more info…

I read there was a place where you could convert your extra set item pieces into other pieces but haven’t found any info if it is.

You do not need guide for this, you just do this quest https://grimdawn.gamepedia.com/The_Tome_of_Eanatum and then your inventors can transmute set items
