Hero Roles
Mastering the various hero roles is essential for crafting an effective team strategy. MLBB divides its heroes into six distinct roles:
Tank
Tanks are the bulwarks of any team, boasting high durability and the ability to soak up damage while shielding their allies.
Fighter
Fighters strike a balance between offense and defense, thriving in close-quarters combat and offering versatility in battle.
Assassin
Assassins are the lethal shadow-strikers, designed to swiftly eliminate critical enemy targets with high burst damage.
Mage
Mages wield the power of magic, dealing substantial damage from afar, often through area-of-effect spells that can turn the tide of battle.
Marksman
Marksmen are the long-range damage dealers, crucial for consistent physical damage output and excelling in the late game.
Support
Support heroes are the backbone of the team, offering healing, buffs, and crowd control to bolster their allies. For those interested in mastering this role, check out our Mobile Legends: Bang Bang Support Guide.
Choosing a well-rounded mix of these roles is key to enhancing your team's synergy and dominating matches.
