"Master, why did you call me?" All of its eyes focused on Leon, who quickly glanced at his Mana Bar, realizing he had less than a minute to form his Dark Pact before his mana ran out.
Leon met the leech's countless, eerie eyes and spoke firmly, "Form a pact with me."
The Abyssal Mana Leech King tilted its grotesque head slightly before bowing. "As you wish, Master."
Dark violet energy surged through the air as the pact began to take shape. A sinister, black tendril extended from the leech, wrapping around its own neck before slithering toward Leon's outstretched hand. The tendril coiled tightly around his wrist, burning a mark of servitude into his skin.
The pact formed was that of an master and Servant with leon being the Master and Leech being the Servant.
A notification flashed before Leon's eyes.
