This spell channels vitality into plants within a specific area. There are two possible uses for the spell, granting either immediate or long-term benefits.

If you cast this spell using 1 action, choose a point within range. All normal plants in a 100-foot radius centered on that point become thick and overgrown. A creature moving through the area must spend 4 feet of movement for every 1 foot it moves.

You can exclude one or more areas of any size within the spell's area from being affected.

If you cast this spell using 1 action and choose a point on the surface of a body of water, you can choose the following effect instead of the spell's normal effect:
This spell channels vitality into the water within a 100-foot radius circle on the surface of a body of water, causing a sudden bloom of life. The surface of the water in the area becomes opaque, covered by vibrant red algae, and the water in a 100-foot-radius, 100-foot-tall cylinder extending down from the surface in the area becomes unbreathable. Creatures within the cylinder that can breathe water are unable to breathe. Additionally, each creature that starts its turn in the cylinder must succeed on a Constitution saving throw or become poisoned until the start of its next turn.

If you cast this spell over 8 hours, you enrich the land. All plants in a half-mile radius centered on a point within range become enriched for 1 year. The plants yield twice the normal amount of food when harvested.
