The Sphinx is a strong Classical Age Myth Unit available to worshippers of Bast. Powerful melee units, they deal both hack and crush damage - this, combined with their high speed, low cost and early availability makes them excellent rush units. They deal bonus damage to Myth Units as well. Sphinxes have a special attack that consists of them turning into a sandstorm, dealing multiple ticks of damage to the enemy that they have targeted. Bast offers two sphinx-specific upgrades, renaming them Criosphinxes and finally Hieracosphinxes; the two upgrades improve every aspect of the sphinxes, including their hitpoints, speed, and attack.
In addition to these attacks, Sphinxes also make great siege units. Because of their high hitpoints and large crush attack against buildings, the Sphinx can be easily utilized in a rush to destroy an enemy's economy early in the game.
