The Sun Stone is an essential ingredient for making "Soul Ashes," and Rod now only lacks this item.
To create it, one needs a portion of Monster Ash, the corresponding complete soul of the beast, ten units of humanity, and a Sun Stone weighing more than thirteen grams.
Once completed, it can summon the soul entity of the corresponding monster to battle.
Although it's a one-time-use item, it can definitely be used as his trump card for saving his life, coming into play at critical moments.
Rod already has a good number of complete souls and Monster Ashes, and humanity is certainly not lacking.
However, as he had no channel to purchase Sun Stones, he had been unable to make them.
But now, isn't the opportunity right before him?
So many Sun Stones, certainly enough for his use.
