Emma Frost is a formidable vanguard with disruptive control abilities and a unique balance between offense and defense. Her diamond form grants her high survivability, while her psychic powers let her manipulate the battlefield, disabling key targets and disrupting enemy positioning. She thrives in teamfights where she can peel for allies while threatening enemy duelists. The key to playing Emma Frost is timing her defensive form and leveraging her CC to protect supports or set up kills. She works best in coordinated teams where her disables can be followed up by heavy damage. Emma also brings utility through her durability, allowing her to absorb cooldowns and draw focus away from more fragile teammates. Her main weaknesses are mobility and reliance on cooldowns. Aggressive duelists and ranged strategists who can kite or force her form early reduce her effectiveness. When her diamond form is down, she is vulnerable to burst damage. In the right hands, Emma Frost provides both frontline stability and game-changing disruption, making her a strong pick in Season 3.5.
