The Crawling Skull is a near-invulnerable enemy that crawls back and forth on the ground, speeding up when the player is on the same level as them. In Rosenkreuzstilette, they can only be destroyed by powerful special weapons such as the Grollschwert, Liebessturm, Lilli and Strudel. Crawling Skulls function similarly to the Spines from the Mega Man series. Enemies and Bosses in the Rosenkreuzstilette series
