Synthesis

Synthesis or Crafting in Celestial Dynasty.

The shortcut key for crafting [Synthesis] is H. When you first roll out your character most of the items you need you can get straight from the quests or events you do.

Certain Bosses or mobs drop those items. Check the World Boss tab or Elite Boss tab for more info in-game.

When you level up your character it is going to need better gear and items. These items you can craft with the Synthesis pop up. On the left side you have the tabs you can browse through and see what you need to craft.

Here is an example; and you can also see Success rate is 60%. So in crafting some will fail and go poof.
 * 1) i need Blue Pebble (M) for my gear to change color and get higher stats.
 * 2) in the pop up you can see that i can craft 31 Blue Pebble (M)
 * 3) to craft those Blue Pebble (M) i need Blue Pebble (L) 2 of those
 * 4) so 2 Blue Pebble (L) makes 1 Blue Pebble (M)
 * 5) press Synthesis to start crafting.

It also cost bind copper to craft. Copper you get from doing tasks (quests) and from boss drops.

Another example Gem synthesis:
 * 1) Select tab Gem from the left of the Synthesis pop up
 * 2) Then select tab Gem as you can see in the picture below.
 * 3) Check what you can craft from the list. In the picture below for example i can craft 3 lvl.2 ATK Gems
 * 4) To craft a level 2 Attack gem i need 4 level 1 attack gems
 * 5) The level 2 attack gem that is going to be crafted
 * 6) the success rate for gem crafting is 100% so no fails. You can select how many you want to craft. The crafting consumes copper.
 * 7) Press tab Synthesis to start crafting.
