Pay Attention to an Enemy’s Level
This may seem like common sense, but with how Sword Art Online: Hollow Realization is designed, you can grow comfortable fighting weak enemies only to be surprised by something twice your level. The mobs in the game tend to be mixes of weak and strong enemies to keep you on your toes. You can see the enemy’s level right above their head before you even approach them. Or, if you happen to be in combat already, it will be on the top of your screen with their health bar.
While it is possible to beat an enemy that is way above your own level (if you’re skilled enough), you may not want to waste your time taking on too many early in the game. You will be revived back in town if you do happen to bite off more than you can chew, but having to slog back to where you were can be a chore sometimes.
