Behavior in game
Often in the game series, if the Player looks behind and sees Slendrina, she will use her look to harm the Player and kill them, as blood spreads across their screen. The time it takes for Slendrina to kill the Player if they look at her depends on the difficulty the gameplay is set. The harder the difficulty, the less time the Player can look away from Slendrina. Slendrina disappears if the Player looks away from her for a few seconds and she doesn't come back until a certain amount of time, which also depends on the difficulty.

Weakness
Throughout the series, Slendrina seemed to not have a weakness, as looking away from her would be the only way of surviving and escaping. However in the game Slendrina X, if the Player manages to put the book on the pedestal, they can trap Slendrina in the book, but they have to look away and then look back at her to draw and copy her face into it while gaining back health.
