As a Crafter, what should I look for in armor?

[Corrderio]

Actually one more thing, everything is explained in those links but what do "output" and "perception" do exactly, and do attribute point allocation matter, what should I be focusing on?

Output/Preception are only for DoLs (Botanist, Fisher, and Miner) so unless you're looking to take one of those up, just ignore that.
