In COX, there were a number of things that players could do to become more effective crafters that were not quite straightforward. There wasn't a big neon sign that said "HEY! YOU WANT TO BE A CRAFTER? YOU SHOULD DO XYZ!" but that didn't change the fact that crafters who knew the ins and outs had a lot of advantages over players who didn't know the fairly easy steps that would significantly increase their effectiveness as crafters. Some things that would have helped anyone.
1.) A dedicated crafting base. If you had a 1-person base that was set up for nothing but crafting, you could easily store valuable salvage, stockpile crafted IOS, have bank access, as well as have a crafting table. Setting up such a base wasn't straightforward, but at the same time it wasn't difficult if you understood why it was important. And considering how important avoiding "by it nao!" was to effective marketeering, I think having access to such a base was important. You could purchase recipes for useful sets cheaply on spec, and store the crafted IOs in your base for future use or for resale on the market.
2.) Using your base to stockpile IOs. Take something as rudimentary and basic as frankenslotting. It was so much easier to frankenslot if you had a stockpile of cheap set triple IOs awaiting newly-leveled characters. You could do the same thing with widely-used IO sets like Doctored Wounds, Crushing Impact, or Thunderstrike. If you had the INF, you could do the same thing with rare IOs or purples.
3.) Expanding your personal inventory via badges. If you memorized the level 25/30 recipes, you got an extra +2 salvage slots per badge. For the level 45-50 recipe badges, you got an extra recipe slot. The extra recipe slots were huge, considering that you could stockpile crafted IOs or salvage in bases, but there was no extra recipe storage beyond your personal inventory.
4.) The extra enhancement slots that you could purchase in the store were freaking amazing.
5.) Increasing AH slots really helped marketeering in general. You could do that via badges or cash shop purchase.
6.) The personal crafting table probably wasn't "worth" the effort put into it, but boy was it nice.
What are some of the tip/techniques that you used in crafting that weren't necessarily "in the manual"?
