Ruby is one of Mobile Legends’ longest-standing fighters, known for a scythe-and-chain moveset that lets her drag enemies into range and then simply refuse to die. She’s less about flashy burst damage and more about outlasting whoever she’s fighting, which makes her a natural pick for players who like grinding down opponents through sustain rather than ending fights in a single combo. Her identity has stayed consistent since her release: a durable brawler who thrives in extended skirmishes.

Role and playstyle

Ruby is typically played in the jungle or as a roamer, using her early game to clear camps and look for opportunities to lock down a single enemy hero with her chain-pull tool. Her core gimmick is a self-heal that scales with how much damage she deals in a fight, meaning the longer a skirmish drags on, the more she benefits relative to opponents who don’t have similar sustain. Her spinning blade ability hits everyone around her, so she wants to be in the middle of a fight rather than picking off targets from the edges, using her pull to force isolated enemies into that radius before her team collapses on them.

Strengths

Ruby’s main strength is her ability to win wars of attrition. Her self-healing means short trades rarely favor the other side, and she can stay in lane or in a fight far longer than most fighters without needing to recall. Her chain-pull also gives her reliable crowd control for a hero in her role, letting her lock down a priority target and hold them in her damage zone while her team follows up, which makes her a solid pick for less coordinated teams that need a hero who can create opportunities on her own.

Weaknesses

Ruby’s damage output is comparatively modest next to burst-focused fighters and assassins, so she struggles to close out fights quickly against high-mobility or high-burst heroes who can kill her allies before her sustain becomes relevant. She’s also fairly reliant on connecting her chain-pull to get full value from her kit — whiff it, and she’s left as a slower, less threatening brawler with no way to force an engagement. Against teams with strong disengage or peel, her drawn-out fighting style can be neutralized before it ever pays off.

Build direction

Ruby’s itemization generally blends physical damage with durability, since her healing scales off the damage she deals but her survivability also depends on straight defensive stats. Early items typically favor sustain and utility to support jungling and early skirmishes, moving into a mix of damage and tankiness as the game progresses so she can keep initiating fights without dying before her healing kicks in. Defensive items should be adapted based on whichever enemy heroes threaten to burst her down before her sustain can offset the damage.
