Silicus Miles Sasitatio is a spell that allows the caster to summon Stone Creatures from the ground and have them under their control.
In Absolute Power: Part 1, it was used by Gwen against Ultimate Kevin. One of the Stone Creatures frees her from the vines Kevin made while four others surround Kevin. The other one joins the group and Kevin is brought to his knees until he absorbs the mana animating the stone creatures giving him access to some mana generation abilities.
Silicus means "flint" and miles means "soldier" in Latin.
