As Bill continued to evade the Beetle King's lightning attacks, his mind raced to devise a winning strategy. He realized that his wind ability could be the key to turning the tide in this battle. With his wind aura boosted and his body moving with incredible agility, he had to find a way to exploit the Beetle King's weakness.
Observing the Beetle King's movements and attack patterns, Bill noticed that the Beetle King had a split-second delay between summoning the regular lightning bolts and launching them with more advanced skills requiring more time before it could reuse them.
These were the cooldowns for the skills that the Beetle King was using, with the basic moves like the lightning bolt having delays of less than a second to others which couldn't be used for several minutes or even hours.
