You craft the serpent (white set as you are calling it) set and make it HQ. Then make sure any craft you plan to really use has adamantite in both mh and oh. Those are not necessary melded pieces as you will want to replace the mh tool with the red script one right away. That is your goal. Once you get that done. your set for making end game goodies like the green and blue tools for gather and crafter.

1. Craft your hq Serpent set.
2. Meld the hell out of it to a point lol.
3. Craft you some stuff for red scripts and 3 weeks later you have enough to get the mh tool on one job.
4. Suggest BSM as you can make several oh tools with that job. (Not required just a suggestion)
5. Keep at this replacing your mh for each craft about every 3rd week.

Of course you can do this many ways but this way is the cheapest albeit maybe not the fastest.
