Blessed Lucky Bonus
As the Lucky Bonus recipe, this one adds small bonuses to the items, but requires the Blessed Oil of Luck - which can be obtained from the Special Box. There's a lower chance to gain the bonuses, but they are much better than the Lucky Bonus. Any item that has been transmuted with this recipe will show up as "Already upgraded!". Items marked as such cannot be used for this recipe.
Any item + Blessed Oil of Luck → returns item, may add bonuses
This recipe has 15% chance to add any of the following bonuses:
+(40 to 60)% Enhanced Defense and/or Damage Reduced by (1 to 2)%
It may take you more than 50 times, if you are extremely unlucky. 15% doesnt mean that within 6 times you will get %DR bonus either. Its a matter of luck rather than math.
