The lich was horrified to find that not only was the magical energy of the ghost ship suppressed, but even his own mana seemed trapped in a quagmire.
In other words, his spellcasting speed and the power of his spells were infinitely suppressed.
Chains whipped through the air as the lich frantically gathered mana. Spells that he could previously cast dozens of in an instant, like Ice Arrows, now took several seconds to conjure just one. And even then, the Ice Arrow was so feeble it was nearly falling apart, let alone carrying any significant power—it might not even reach its target before dissipating.
"My lord, we can't cast magic anymore," the female vampire said grimly.
"Damn it! Do you think I don't know that?" the lich roared in fury, casting an enraged glance at the banshees and ghostly spirits under his command, all of whom looked weak and dispirited.
