Finale

Ren was nearing the end of his mana reserves as he discharged the fireballs into the air. With precision, he imbued each fireball with a calculated amount of mana, ensuring a delayed explosion for each projectile when the mana imbued goes out of control. A small grin formed in the corner of his lips when he saw that Donovan fell into his trap, giving him sufficient time to set up the fireballs while Donovan was fully focused on defending against him.

The fireballs he launched were a mix of flashbang and speed-boosting fireballs. 

When the flashbang detonated, the entire arena erupted into a dazzling display of light and noises. Concealed by the blinding brilliance, Ren swiftly traversed the arena at an astonishing pace. With precise timing of each explosion through calculation, he simply needed to follow a predetermined path to reach Donovan.
