Luck, also known as mercy, is a cumulative bonus that increases your likelihood of success for chance recipes.
Luck is linked to the recipes, not to specific evolvable items (such as the Dragon Egg), with a single Luck bonus applying to all crafting attempts using that recipe. Luck bonuses persist through reincarnation.
Identified by a gold dice icon, these recipes offer a success/failure outcome. Some chance recipes (such as boons) offer an improved result, while others are used to evolve a specific item. These recipes have a bar on the recipe card that reflects your current chance of success; mousing over or tapping on this bar will show your Luck bonus. A list of chance recipes can be found here.
All chance recipes have a base chance of success, the likelihood of success expressed as a percentage. Luck boosts this chance of success by a small amount per point of Luck bonus.
Luck can be increased in three ways:
- Each unsuccessful crafting attempt increases your Luck for that recipe by +1.
- Black Gems increase your Luck for that recipe by up to +10.
- Blue Gems provide a temporary bonus equivalent to up to +18 Luck for that crafting attempt only.
You may only add one gem per crafting attempt.
When you achieve a success result for a chance recipe, your Luck for that recipe is reset to 0.
