Sisters of Avelorn

Sisters of Avelorn are a High Elves unit in Total War: Warhammer II ' s downloadable content, The Queen and the Crone. Guardians of the sacred places of Avelorn, these peerless archers are incorruptible.

Description
Sisters of Avelorn are keen-eyed archers, Elf maids chosen from the ranks of the citizen levy by the Everqueen's personal decree. By tradition, only the most gifted are welcomed into the Sisters of Avelorn, for just as the Everqueen embodies all that is ideal and unblemished in the Elven race, so too must her chosen guardians – not only in mind and body, but also in pursuit of the spiritual. Such measures serve to raise the warriors of the Maiden Guard above the petty intrigues that often pervade the Everqueen's court, ensuring that they remain incorruptible.

Strategy
The magic arrows used by the Sisters ignore physical resistance, pierce armor, AND do extra damage to regenerating creatures. Suffice to say they are one of the most deadly ranged units in the game. Additionally Sisters have surprisingly good melee attack/defense, leadership, and weapon damage for ranged units. Even against dedicated melee units the sisters are quite good at holding their own in melee. That said, their health and armor are fairly low, meaning they will typically lose extended engagements or against high tier melee units, and are fairly vulnerable to focused return fire. In general you will be best served if you're able to keep the sisters continuously firing on the enemy without taking focus from enemy ranged units.

=Doomstack=

Sisters of Avelorn are the most effective unit in the High elf army roster. They have great missile damage and decent melee stats. This makes it possible for Sisters of Avelorn to function without a front guard, as they can decimate any approaching enemies and deal with the stragglers if they reach melee range. A doomstack for the High Elves, the most effective army one can create for the faction, consists of a lord (preferably punitive trait), a handmaiden (preferably resistant trait), a light wizard (any trait), 15 Sisters of Avelorn, and 2 Eagle Claw Bolt Throwers. This army could single-handedly take on multiple enemy armies (except maybe other doomstacks) and come out on top.

Due to the High Elves' strong late-game economy, it is totally feasible to sustain 8 or 9 of these doomstacks to finish up your late campaign.
