Senna vs Hwei Counter Pick
Matchup Summary
What the Data Means
Hwei brings ten castable options into a matchup where Senna brings four. Subject: Disaster, Subject: Serenity and Subject: Torment each replace his abilities with a different set, covering damage, utility and crowd control in turn, and the price is a difficulty rating of 9. Patch 16.13.1 counted 733 of these pairings and Senna won 46.9% of them, graded Hard, and breadth of options is the reason rather than raw damage.
Her 50-unit range advantage, 600 against 550, is largely cosmetic, because his output comes from abilities rather than basic attacks. Signature of the Visionary primes a champion on the first damaging spell and completes it on the second, which suits a kit able to open with control and finish with damage from one rotation.
Senna’s 530 base health and 25 armor, ending at 2,043 and 93, leave no margin once a signature completes, and Spiraling Despair expands from the first champion struck while slowing everything near it. The way back in is early: Hwei starts on 21 armor and 580 health, the softer opening line of the two, and his mixed damage classification means Senna gains little from a single resistance. Both spend Mana and both move at 330, so the exchange is decided by which cooldown is available rather than by footspeed. Curse of the Black Mist is the one tool that hides her approach, and against 580 base health a full rotation of her own is still lethal.
