Artifacts

They are objects that can have very diverse effects, like doubling damage to a specific beast or give buffs to the Druid. They can be obtained by buying boxes in the shop, in the infinity stage of Necro Cave, by selling fish to the vendor in Mermaid island and through combining other artifacts. They can have four grades: C, B, A and S. The Druid can only equip one artifact at the same time.

Boxes
Boxes can cost 50,000 gold, 170,000 gold and 210 diamonds. Each box contains three artifacts. The 170,000 gold boxes have a higher chance of containing higher grade artifacts than the 50,000 gold ones and the 210 diamonds boxes have a higher chance that the other boxes. These diamond boxes seem to contain all artifacts, including A and S grade artifacts.

Combination
By combining two artifacts of the same grade, there is a chance to get a higher grade artifact (If they are C, you may get a B, if they are B, you may get an A and if they are A, you may get an S. It is not possible to combine S grade artifacts (If you try, the game will show the next message: "I can not strengthen it anymore."). If the combination fails, you get instead an artifact of the same grade. It is possible to increase the chance of getting a higher grade artifact by adding more artifacts to the combination, with a maximum of ten artifacts. All artifacts involved in the combination will be lost.
 * The base percentage of combinig two C grade artifacts is 50%. By adding a C grade artifact, the chance of getting a B grade artifact increases by 5%, by adding a B grade artifact, it increases by 25% and by adding an A or S grade artifact, it increases to 100%. The cost of combination is 50,000 gold.
 * The base percentage of combinig two B grade artifacts is 22%. By adding a C grade artifact, the chance of getting an A grade artifact increases by 1%, by adding a B grade artifact, it increases by 5%, by adding an A grade artifact, it increases by 26% and by adding an S grade artifact, it increases to 100%. The cost of combination is 170,000 gold.
 * The base percentage of combinig two A grade artifacts is 6%. By adding a C grade artifact, the chance of getting an S grade artifact increases by 0.17%, by adding a B grade artifact, it increases by 0.83%, by adding an A grade artifact, it increases by 4.33% and by adding an S grade artifact, it increases by 22,33%. The cost of combination is 540,000 gold.
