i had 400 artifice at around lvl 32 or something, and tbh i crafted maybe a total of 6 items that i actully used up to lvl 47, every other crystal, ench i got from buying them off commandation mods vendor on every planet i got to; cheaper at higher level, then spending 2k credits per mission, sending comp's out just to get random crap material. for me artifice was no good, tho i didn't really put much effort into it other the just maxing it out. yesterday i switched to biochem for the stimps and packs. and i dont regret it one sec, not only do you get 2 extra medals in wz's from using packs (medic and surgeon, 2.5k/5k singel heal), but you get a much better stat increase from a stim then you do with a new hilt, crystal, ench. some might argue that the relics you get from artifice at 50 are great (the artifact ones), imo they are not ! yes they do increase your crit/power/surge/ w/e for an amount of time, but they do not benifit to your stats. if im not totally mistaken (cba research right now) then you can get prototype relics form the dark/light vendors at lvl 50, that have +52 endurance on them, they are not unique so you can equip two of them, and get +104 endurance extra, and they come with an on use bonus. as for leveling biochem, heres a guide i found on the these forums wich is great for leveling up any cs. the amount of materials needed is actully less then the guide suggests since it does'nt include reverse engineering: The post: http://www.swtor.com/community/showthread.php?t=5432 Google docs spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0ApFZQPDxUk6WdGpra1B6UzJXWUotX21iWk41YmlVbkE&hl=en_US#gid=0
