Variant Night Elf Huntress skin.
Unlike their Night Elven counterparts, the Sisterhood has their own Huntresses, mounted a silver-skinned tiger called the Bengalaas. They combat both day and night with fast strike attacks and they can reveal invisible units with the Sentinel. Though heavily armed and moderately armored, the Sisters' Huntress is a force to be reckoned with.
Update on 05/06/21: Improved skin and icon.
