The Sphinx of Usekph (Necrosphinx)

The Sphinx of Usekph (Necrosphinx) is a Tomb Kings monstrous Construct unit introduced in Total War: Warhammer II with the Rise of the Tomb Kings DLC. The fury of the gods made stone, these chosen Sphinxes augment their brutal scythe-attack with magic and fire.

Description
Necrosphinxes are nightmarish beasts of destruction that glide through the air in bounding leaps before falling amongst their terrified prey, scything down the living as mortals reap the wheat of the field. None can stand against such terrifying beings, and only when all before them have been butchered will they stop. A Necrosphinx is a bizarre and horrifying statue - a strange amalgamation of the mythical beasts that are said to inhabit the Nehekharan Underworld, maintaining order amongst the honoured dead. It has a torso and face of a man, and is armed with gigantic, scything blades that can sever the neck of a Dragon in a single slice. Many also have a scorpion-like tail, better enabling them to stand sentry against the predations of evil. Finally, sprouting from the statue's back are a pair of ornate wings which mimic those of the falcons that circle the highest levels of the Underworld, keeping watch so that the souls of the damned may not escape.

Strategy
One of the best monster killers in the game, the Sphinx is a terror to most anything large. It has great melee stats and a large bonus vs. large that will ensure it dominates any duel it gets in. It also has flaming magical attacks so regeneration will only amplify the Sphinx's damage. There are some niches where fire damage can hamper its effectiveness due to their flame or magic resistance. The Flamespyre Phoenix and Arcane Phoenix are a good example. On the same note, a forest unit like a Treeman would be shredded (40% flame weakness and the sphinx's magic attacks would ignore their 20% Physical resistance)

On top of this, Tomb Kings have relatively little access to fire damage, so this unit offers a valuable utility.

Teaming the Sphinx with another large unit or a mobile chariot (Settra on the Chariot of the Gods for example) squad can ensure that the Sphinx never gets bogged down or its targets never get away.

Trivia
The Liche Priests do not think that a Necrosphinx is animated by the soul of a valiant warrior like the other war-statues that walk beside the Tomb King's skeletal legions. Instead, they believe that the sinister gods, Pha'a and Usekph, breathed life into these horrifying creations.
