How does recipe affect the talisman
Rarity of talisman affects its bonus. The more powerful talisman is, the bigger bonus it will give to a dragon, and the more resources you will need to craft it.
Besides, recipes have a certain chance of crafting. This chance can be 50%, 75%, or 100%. The bigger chance is, the more resources you will need to craft it. If crafting fails, then recipe and resources are wasted.
