After a while, the clone freed itself from the illusion when the clone managed to defeat the hydra, so Billy decided to undo the clone and absorb the knowledge that it had obtained. It wasn't bad, considering that Billy only needed to keep the illusion active for twenty seconds, and that consumed one thousand points of mana per second, but it was far from perfect.
The skill Fire Immunity received 1550 experience points.
The skill Cold Resistance received 3300 experience points.
The skill Gravity Resistance received 3300 experience points.
…
Billy could have obtained the double amount of experience he had just used his innate skill, so it felt a bit cheap, but he didn't give up yet. He tried to control the flow of time in Perfect Illusion and Dream World, but he failed. Even when he tried to use more mana, it didn't work since the skills were at the max level already.
