How To Get Class Grade Rewards
Class Level Up (Level 75 > Level 76)
The only way you can get account growth items as rewards from the Class Grade system is by leveling up continuously.
You can level up faster by doing certain tasks in NNK:CW, like clearing Main Story Quests or AFK farming mobs when you’re not actively playing.
Energy Drink (Shop)
One important thing I’d recommend you do regularly if you want to level up faster is to farm Energy Drinks.
Consuming Energy Drinks will allow you to gain levels much faster while you’re farming mobs, which also lets you acquire Class Grade rewards more quickly.
