As a spell like ability you can meditate during a long rest and cause the land around you in a 200-foot radius to become overgrown. If repeated every day for a year in the same space the effects will become permanent. 

All normal plants within the 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 ability over 16 hours, you enrich the land. All plants in a mile radius centered on a point within range become enriched for 1 year. The plants yield twice the normal amount of food when harvested.

Your Strength score increases by 2, and your Charisma score increases by 1.

Your size is Large. You count as one size larger when determining its carrying capacity and the weight it can push, drag, or lift.

Your base walking speed is 30 feet. You gain wings that grant you a fly speed. You are partially amphibious and can breathe water for an up to hour every day before you need to resurface. 

You are immune to poison because of your new form. You gain a breath weapon from this form as well. Once per long rest you can empower your form and gain a bite and claw attack. 

You can use your action to exhale destructive energy. Your draconic ancestry determines the size, shape, and damage type of the exhalation. When you use your breath weapon, each creature in the area of the exhalation must make a saving throw, the type of which is determined by your draconic ancestry. The DC for this saving throw equals 8 + your Constitution modifier + your proficiency bonus. A creature takes 2d6 damage on a failed save, and half as much damage on a successful one. The damage increases to 3d6 at 6th level, 4d6 at 11th level, and 5d6 at 16th level. After you use your breath weapon, you can’t use it again until you complete a short or long rest.

You can speak, read, and write Common and Draconic. Draconic is thought to be one of the oldest languages and is often used in the study of magic. The language sounds harsh to most other creatures and includes numerous hard consonants and sibilants. You also gain the senses of a Dragon granting you blindsight and darkvision.
