In Diablo Immortal, Wizard is the most vulnerable but deals the most AoE damage.
The highest DPS WIZARD build in Diablo Immortal | Wizard Endgame Building Guide
The Wizard is considered a glass cannon class as it has the weakest defense but packs the highest AoE damage in Diablo Immortal.
This class is the best choice if you want to blast through monster packs as quickly as possible. The Sorcerer's damage allows you to integrate into groups of any difficulty.
In Diablo Immortal, most Wizards go all-in on AoE burst damage. The class also has some crowd control abilities that work well in solo play and PvP, but otherwise it's all about the damage.
