The Five Elements Ancient Treasure Formation was not limited to using the thunder-type Heavenly Thunder Drum as its center to cast Thunder Element Spells.
Instead, a treasure of any element could unleash divine abilities of its own element.
For example, if the Heavenly Thunder Drum served as the formation's primary treasure, Thunder Element Spells would form its core.
If the fire-element Treasure Refining Furnace served as its primary treasure, it could unleash fire-element divine abilities.
In other words, the Five Elements Ancient Treasure Formation could switch between spells of its five elements-a truly heaven-defying divine ability...
Its most powerful attack, naturally, was to unleash the divine abilities of all five elemental treasures at once.
Unfortunately, unleashing all five treasures together required not only mutually complementary elemental properties, but matching divine ability attributes as well.
Of the five treasures in Ye Han's current Five Elements Ancient Treasure Formation, only four belonged to the five elements. The thunder-type Heavenly Thunder Drum merely filled the metal-type slot, so unleashing a five-element divine ability was naturally impossible.
The other four ancient treasures also had differing divine ability attributes.
The Darkwater Heaven-Earth Bag he had used before had even disrupted the five elements because its properties carried too much yin energy to fit with the others...
Of course, the Five Elements Ancient Treasure Formation had quite a few flaws. First and foremost, activating five ancient treasures at once consumed a staggering amount of spell power. Ye Han had now refined all five treasures to around seventy percent.
Yet activating the Five Elements Ancient Treasure Formation once still consumed eighty percent of his spell power. If he did not have the Purple Cauldron to replenish it at any time,
a single activation of the Five Elements Ancient Treasure Formation would leave him with no spell power
