A summoner's damage output came from summoned beasts. If a summoned beast's level was reset to zero, the summoner's combat power would drop by at least 90%. This was also the greatest drawback of having summoned beasts take Phantom Beast Pills.
However, Hidden Profession summoners had two summoned beasts, while Dual Profession summoners had three. As the number one summoner in Heavenly Tribulation, Zhi Yue could even summon five beasts into battle. Therefore, even if one or two of her summoned beasts had their levels reset to zero, she could still rely on the others to maintain formidable combat power and quickly help the beasts that had taken Phantom Beast Pills level up.
It was precisely because she had five summoned beasts that, even after the Black Dragon King took a Phantom Beast Pill and had its level reset to zero, Zhi Yue could still rely on Icefire, the Golden Winged Eagle King, and the others to kill monsters. Their farming efficiency was quite good as well.
Although the Black Dragon King did not gain ten times the experience from killing monsters after taking a Phantom Beast Pill like players did after taking a Reincarnation Pill, summoned beasts originally needed only one-tenth of the experience required by Normal Players to level up. Coupled with Icefire and the others' formidable combat power, it still leveled up very quickly. At the current rate, it could reach over level 200 in less than half an hour.
Even though the Black Dragon King's growth aptitude would increase with every advancement after taking a Phantom Beast Pill, its combat power at level 200 was clearly inferior to what it had been before taking the pill. Fortunately, it could still equip summoned beast equipment and use all its skills even after its level had been reset
