Tree of Life

This Spell has 3 different Phases, each Phase having a different and stronger Effect. While you concentrate on this Spell you start to levitate 10 Feet of the ground, entwined in roots out of pure light. From far away, the light makes you look like an ancient Tree made out of divine light. While you concentrate on this Spell your movement Speed is reduced to 0 and you can't use your turns for anything else but channeling this Spell.

Phase 1. You start to levitate and vines of light bind you to the floor. Around you, the ground starts to shine dim light in a 30 Feet radius. Every creature that is friendly to you within the radius, regains 4d4 Hit Points. The Caster takes 4d4 necrotic damage, since he infuses his own Life into the ground below him, sacrificing his own health.

Phase 2. The vines go on growing and building stronger roots towards the ground. An ever growing Tree out of pure light starts to emerge on top of your shining body. The ground shines dim light in a 60 Feet radius now. Every creature that is friendly to you within the radius, regains 8d4 Hit Points. Furthermore, everyone standing on the dimly shining ground starts to feel lighter and gains double the movement Speed. On top of that every saving throw is done with advantage. The caster takes 8d4 necrotic damage, while infusing his Life energie into the ground around him.

Phase 3. The Tree forms itself into a giant majestic Tree made of bright Light. In an radius of 90 Feet, the ground now shines bright light. Every creature that is friendly to you within the radius, gains 12d4 Hit Points, has double the movement Speed while moving on this ground, has advantage on saving throws and gets additionally up to 10 temporary heal points should the Heal exceed their maximal Hit points. The caster takes 12d4 necrotic damage, while infusing his Life energie into the ground around him.

At the end of his Turn, the Light starts to disperse and the Caster starts to slowly drift towards the ground. Should the caster die due to the damage of this Spell, he/she is instantly stabilized.
