I'm making this guide in response to the Bruce Waynes of the world who are too good to be having fun with crafting and just want to PL their craft to 100 and think "it's cheap now anyway". You can check wikis for items and materials and decide what to do when. I'm just providing the least expensive synths you should take to waste all of your money so you don't have to wander along the long list of recipes on wiki that you'll eventually do anyway because there's no trusting a mere guide on the internet thereby making reading this thread pointless.
And Yes, I'm rushing this guide. Time is money for us rich folk. And you're powerleveling. For cheap. You ain't got time reading helpful guides. The only truly pricey thing in this entire list is lamps which you probably won't do anyway because mats will slow you down. You can go searching for alternative synths if you want but I'm pretty 100% certain everything I list are the best possible, simple, PL worthy, and cheap options to take.
