Star Wars Jedi Fallen Order guide and walkthrough
This particular guide of Star Wars Jedi: Fallen Order is about the fight with the Second Sister which takes place in the prologue of the game. Please note: you can’t defeat the Second Sister in the prologue, it’s more of training for Cal.
The first duel of Cal and Second Sister takes place after completing the train part, at the end of the prologue. Remember Cal is too weak to defeat the Second Sister and the duel should be taken as a tutorial for the game.
During the duel, Second Sister uses “red attacks” which means the coming attack cannot be blocked. At this time, use dodges and rolls by pressing the dodge button twice. After her attack, you can attack her but don’t expect that you can damage her.

At the end of the fight, the duel will be with the lightsaber. Remember to keep pressing the attack button during the fight. Either Cal loses the battle with Second Sister or enough time has passed. Hereafter, Cal escapes in a spaceship.
