Synthesis Machine
Starting at level 9, the Synthesis Machine unlocks advanced item enhancement - boost your item’s quality, add extra stats or chip slots, or forge entirely boosted gear.
It works similar to standard crafting but always consumes special, 
Synthesis Fuel even on failed or incorrect attempts, so only fuel is lost and your other materials remain intact. You can obtain fuel from quests, buy from vendors in towns, loot from monsters and chests.

- Synthesis Fuse: merge identical items to get the same item one quality step higher.
- Synthesis Enhance: use boosters to push quality and reroll stats and Talents .
- Synthesis Craft: start from a known recipe, add special parts, and create new gear that will roll Upgraded or Overclocked.
Synthesis Fuse

Also while you fusing items you also have a chance to fuse even better quality item than targeted one.

Synthesis Craft
The Synthesis Machine can be used to craft items with various bonus attributes.
Depending on the materials and items consumed during the synthesis process, the resulting gear may become Upgraded or Overclocked. For a brief overview of these upgrade features, refer to this article.
When crafting with the Synthesis Machine, the process always begins with the standard recipe for the desired item, which must already be known by your character.
From there, you can enhance the base recipe by adding or substituting specific components to achieve your desired outcome.
Similar to ordinary crafting, Synthesis Craft has a chance to "proc" items of higher rarities - Uncommon, Rare, or Epic - independently of your profession proficiency. Even with 0% profession skill, you can still roll an Epic item via Synthesis Craft.
Approximate Chances to get higher quality items:
- Uncommon - 15%
- Rare - 6%
- Epic - 2%
Basic Upgrade Rule: To craft an Upgraded or Overclocked item, include ingredients of higher quality than the recipe requirement. For example, if a recipe calls for an Uncommon Bow, substituting a Rare Bow will yield an Upgraded Bow; using an Epic Bow produces an Overclocked Bow.
