Using his new spell mastery, Astaroth shot magnetic bullets at every monster in his line of sight, hitting over fifty of them in a minute. Once he had hit them all once, he smirked.
Now came the actual damage.
Activating Thousand Thoughts, Astaroth recreated the process he had used to create the Cyclone of Blades spell. Firing his Magnetic Bullet spell repetitively, aiming them at the sky, he burned through his mana like crazy in the ten seconds of Thousand Thoughts.
Once the skill deactivated, he watched as the bullets flew upward for a while before losing their momentum. Now came the true test.
As the bullets fell back toward the ground, their magnetic property started pulling toward the foes Astaroth had hit previously, giving them a burst of acceleration.
