Coil of Jörmungandr

As you tap into the ancient power of Jörmungandr, the World Serpent, you transform into a colossal serpent, embodying its immense size and strength. Your body stretches out, covered in scales as dark as the deepest abyss. While in this form, you gain the following benefits: 

• You possess a powerful Constrict ability. When you successfully hit a creature with a melee attack, they take 3d8 + your Druid level bludgeoning damage, and they must make a Strength saving throw against your spell save DC or become restrained by your coils. While restrained, the creature takes 1d8 bludgeoning damage at the start of each of its turns until it escapes by succeeding on a Strength check or the spell ends.
• You can use your bonus action to make a Bite attack. The Bite attack deals 4d10 + your Druid level piercing damage, and the target must make a Constitution saving throw against your spell save DC. On a failed save, the target is poisoned for 1 minute, taking 2d8 poison damage at the start of each of its turns. The target can repeat the saving throw at the end of each of its turns, ending the poison effect on a success.
