Use the "Purple Flask" Station to combine two Runes into a single Rune with both of their effects.
Each combination will have a gold cost and a success chance. If the combination fails, you'll lose the gold, but keep the Runes, so you can try again.
Runes with higher odds are harder to combine and cost more for each attempt.
Adding a Luck Sphere to the combination increases its chance of success. Doing so will consume the Luck Sphere. If a Rune is too powerful, you won't be able to do it, no matter how good your luck Sphere is.
The rune in the left slot maintains 100% of its duration time.
The rune in the right slot will add 50% of its duration time to the rune in the left slot.
You can combine runes with one or more effects.
The Rune in the left slot is renamed "augmented" when successfully combined.
The rune's image is determined by the rune placed in the left slot.
