Senna

Senna stands in a niche of her own: a marksman who grows without limit while working as a support. Her Absolution passive snares souls in the Black Mist whenever units die nearby, and each soul she strikes permanently adds bonus power to her Relic Cannon. Since gathering Mist replaces standard farming, Senna can build real damage from the support slot without pulling gold away from her carry, which explains why she shows up both as a support and as an unorthodox ADC.

Her kit fuses healing and poke into individual casts. Piercing Darkness launches a beam of light and shadow down a line of targets, restoring health to allies it crosses while wounding enemies, so a single button handles both roles. Last Embrace releases a Black Mist wave that clings to the first enemy it strikes, rooting that foe and anyone standing close by after a short delay, which gives her dependable pick potential in lane and around objectives.

Global reach and vision denial

Curse of the Black Mist engulfs Senna and nearby allies in a concealing storm, transforming teammates into wraiths that cannot be targeted by clicks. It is a strong option for flanks, objective setups, and getting out of bad collapses. Dawning Shadow works across the whole map: a beam that shields each ally along its path while damaging enemies caught in its center, allowing Senna to affect fights anywhere on the field.

Her drawbacks stem from what she is: a long attack windup, slow early damage, and reliance on stacking mean that a weak laning phase can snowball against her. Senna fits patient players who enjoy gradual, compounding growth, accurate skillshot angles, and hybrid carry-support decision-making.
