Mirsa

Mirsa is a Light Thief who fights as a fast, single-target striker rather than a wide-hitting cleaver. Both of her attacks scale their damage with her own Speed, so the faster she is, the harder she hits, and her basic attack has a chance to slow the target. Her real specialty is her cooldown-5 ambush, which silences one enemy for a turn so they cannot use any skill but their basic attack. She also runs a strong evasion engine: a passive raises her Evasion, and every time she dodges an incoming hit she reduces her own cooldowns by a turn and gains a Speed boost, letting her bring that silence back online faster.

Counters

• Enemies who depend on one key skill — Her ambush silences a single target for a turn, shutting off all of their skills except the basic attack. That neutralizes a healer's revive or cleanse, a key cleaver's hit-all nuke, or any setup unit who relies on landing one specific ability on cue.
• Slow opponents and turn-order races — Both of her damaging skills scale with her own Speed, and she sits in a very fast Speed band that is pushed even higher whenever she dodges. Her basic attack can also slow the target, so she tends to win the race to act and can land her silence before the enemy moves.
• Single-target attackers who must hit her — Her passive keeps her Evasion high, and dodging is rewarded: each successful evade trims her cooldowns and grants Speed. Hitters that funnel attacks into her risk whiffing and feeding her engine instead of removing her.
• Drawn-out fights against cooldown-reliant kits — By repeatedly silencing and slowing while accelerating her own ambush cooldown on every dodge, she can keep an enemy locked out of their important skills across a longer trade than a one-shot disruptor could.

Countered by

• Cleanse and effect immunity — Her whole threat is the single silence and the slow. An ally cleanse pops the silence early, and a pre-applied immunity buff blocks it outright, leaving her with only modest single-target damage.
• Buff removal and buff-duration cuts — Her Speed-up buff is the fuel for her damage scaling and her dodge engine. Stripping or stealing that buff, or shortening its duration, slows her down and weakens every hit she throws.
• Guaranteed hits and ignore-evasion effects — Her defense leans heavily on dodging. Attackers that cannot miss, or that ignore evasion, strip away her survival and deny the cooldown-and-Speed payoff she gets from dodging.
• Burst before she can ambush — As a fragile 3-star Thief with low base HP and defense, she is squishy, and her silence sits on a long five-turn cooldown. A team that opens with heavy burst can delete her or simply outlast a single silence before she can apply it again.
