So I just saw this on Reddit, Thought I'd repost it here.
Check the Mystic Weapon section to see how you can craft exotic max-stat weapons with 50 skill points
Update: It seems like the recipes with scrolls are exotic weapons or armors. This means you can get an exotic weapon for 50 skill points, mystic coins, and some mats. We should figure out what exotic weapons each recipe gets so people can get the exotic they want.
Also, probably some of these recipes are for legendary weapons precursors, and we should find out which ones they are.
I'm pretty sure a lot of people have figured out Mystic Forge recipes, but are just hording the information to make profit, so I'm trying to share what I know and aggregate info from the community.
Quick primer on the Mystic Forge
The Mystic Forge does 2 things:
Random items when you combine 4 random items
Set recipes that give you the same thing each time. A lot of these are level 80 exotics weapons/armor. I'm pretty sure each recipe with a scroll gives an 80 exotic. We just have to figure out which recipes give what.
So I bought a lot of singletons of crafting materials so I could see what recipes the Mystic Forge has. Here's what I found. Here's a list of shorthand I use (Miyani is the NPC next to the Mystic forge)
Wine = Elonian Wine - 25.6 silver from Miyani.
Scroll = Eldritch Scroll - 50 skill points from Miyani
Crystal - 5 for 3 skill points from Miyani
C. Dust - Crystalline Dust
When I refer to fine crafting materials like bones, I mean the tier 6 version (e.g. Ancient Bones). Anything lower won't work, but you can transmute lower tiers up using philosopher stones.
Common and Fine Material Promotion
Check the wiki http://wiki.guildwars2.com/wiki/Mystic_Forge. This will tell you how to turn copper or into iron ore and large bones into ancient bones, for example.
2 Core + 1 Crystal + 1 Wine + 1 C.Dust = Lodestone
For example, if you use two Molten Cores you will get one Molten Lodestones. This is useful because I'm pretty sure some of the Lodestones, like Crystal Lodestone, don't even drop from enemies since there are no high-level branded enemies
Upgrading Siege Weapons:
5 mithril ore + 5 elder wood log + 2 siege weapons + siege masters guide = stronger siege weapon
Mystic Weapon (level 80 exotics with particle effect):
DON'T TRY TO CRAFT THE MYSTIC RIFLE - IT'S BUGGED TO GIVE YOU A LEVEL 61 ITEM
1 scroll + 30 coins + 5 component A + 5 component B
For example, to make a sword you use 5 orichalcum hilts and 5 orichalcum blades. It only accepts level 80 components (so orichalcum components)
Some people are having trouble, so here's a more thorough explanation. Go to http://www.gw2db.com/ and then go to recipes for the craft that makes the weapon you want. Then click on one of the pearl weapons of the type you want (the affix doesn't matter, so Berserker's or Carrion or any of those is fine). Now look at the ingredients of that recipe. One will be an inscription, and the other two will be the components you want.
For example if you want a greatsword, you would look at http://www.gw2db.com/recipes/8487-berserkers-pearl-broadsword and see the components are Orichalcum Greatsword Blade and Orichalcum Greatsword Hilt. So then the recipe you would use is
1 scroll + 30 coins + 5 ori greatsword blade + 5 ori greatsword hilt
and you would get Mystic Claymore
See the bottom for a gallery of Mystic weapons and their stats that I've collected so far.

There are also probably recipes using the other lodestones, but I ran out of money and couldn't buy them to find out. Let's work together as a community and chart this unexplored territory! I'm pretty sure some of these recipes at least give you the exotic components for legendaries.
If the reddit community can band together and chart new territory, then I think that would be awesome! To the best of my knowledge the results of these recipes isn't available publicly anywhere.
