Unlike Cultivation Spirit Beasts that formulates a core at their 1-star level. The mana beasts formulate their core at Lvl 50.
Without formulating a core, a mana spirit beast wouldn't be able to enter Level 50.
So, in this entire dungeon, the Moon will alpha is the only beast with a core.
Leon knew that the Alpha had a reason to go to the peak once things turns awry, it was able to activate it's insane blood moon skill while up.
And Leon though not completely sure, knew that blood moon might somehow be able to counter his shadow abilities, so he has to kill the Alpha before it reaches the peak.
With his shadow movement ability, he'll be able to catch-up with the Alpha in no time. If he had been chasing the wolf on foot, then he might have stand no chance in catching up to the Alpha. But luckily, that was not the case.
