The Progenitor's Playground

Upward flowing mist of blood fills a 20- foot-radius, 40-foot-high cylinder centered on a point within range. Each creature in the cylinder is considered heavily obscured to everyone except the caster. If the caster of this spell is inside the cylinder, they may use a bonus action to appear anywhere they can see inside the cylinder as long as it is an unoccupied space. If there is a hostile creature within 5 feet of the caster when they appear in this way the caster may immediately make a melee attack against those creatures as a part of that bonus action.
