Chapitre 59: The Hall of the Luminous, Part Twenty-Four

Once Neve's mana was fully recharged, she finally put that drake out of its misery. 

... In a while. Before that, though, she had managed the EXP she gained. It was quite a lot.

[... Holy shit.] 

EXP Gained: 900

EXP: 1340/480

Level Up!

She hadn't managed her increased levels in the middle of waves up until now for the simple reason that the EXP she'd been gaining didn't really merit it.

As this wave showcased, however, there was a very real chance that these five waves would result in Neve leveling up quite a bit. In that case, managing her EXP could end up being what lets her survive the latter fights. 

She leveled up 3 times, ending up at level 51.
