Diablo Immortal LASSAL GUIDE
In Diablo Immortal, Helliquary is a unique system that allows you to fight unique bosses with an 8-member party. You can use the Helliquary to seal the remains of the Helliquary bosses, increasing your character's useful combat rating.
Spending time finding and defeating Helliquary bosses will help your character become stronger and take on more challenging enemies later on.
Lassal is one of the hardest bosses in the game, and many players have trouble defeating him. Since it contains four phases, you will need a lot of determination and grit to defeat this raid boss.
