Uranium Fever

You conjure a faintly glowing green stone at a point you can see within range. The stone radiates a sickly energy and you can faintly taste metal.

• The Rush: At the start of each creature’s turn within 10 feet of the stone, or when a creature enters that area for the first time on a turn, it must succeed on a Constitution saving throw or become unable to willingly move farther away from the stone until the start of its next turn. The creature may repeat this saving throw at the start of each of its turns.
• The Exposure: At the end of each creature’s turn within 10 feet of the stone, that creature takes 1d6 Radioac Radiant damage.
• The Snapback: If a creature affected by the stone is forcibly moved outside the 10-foot radius, or if the stone itself is moved away from the creature, it suffers 2d6 psychic damage as its mind violently snaps back to reality.

The rock counts as magical and cannot be destroyed except by dispel magic or similar effects.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the Radiant damage increases by 1d6 and the Psychic damage increases by 2d6 for each slot level above 2nd.
