The opportunity that Lyssandra had obtained in the novel and handed over to Elrik in exchange for him entering her harem wasn't easily obtainable.
In the novel, Lyssandra had relied on an entire team of low-rank wizards, some of whom were enlightened, and only then was she able to secure it.
This implied that a group of at least four low-rank wizards was essential to go for that opportunity. Otherwise, one would only be courting death.
Valerius could reduce the required number by one by becoming a low-rank wizard himself.
He was only two level-ups away from becoming a low-rank wizard.
It would take a few days of risky hunting in the starlit woodlands to reach that level.
But he had a better plan.
His strategy was to aim for the protagonist's very first fortuitous encounter.
