Field of Vineyards (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Range:||Self (30-foot Radius)|
|Components:||S, M (A pile of rose seeds and a poison bottle)|
|Duration:||Up to 1 minute|
When releasing the rose seeds, vines appear from all sides and make the terrain difficult (30 feet radius), from these vines arise roses that release a powerful poison that deals 3d6 poison damage every time a creature moves more than 10 feet at a time within this area. Creatures in a 15 foot radius when this is used must succeed a Constitution saving throw, becoming restrained for 1 minute. They may retry this saving throw at the end of each of their turns to end this early. Every creature of your choice that ends their turn in the vineyard must succeed a Strength saving throw or be pushed 15 feet away from the center.
You can stop this spell with a bonus action, and can be continued by spending a level 1 spell slot (example: if you stop at the third round of the spell and do this, it will return with 7 more rounds).
