Tune of the Earth

Parts of the Kena's power came directly from the Earth itself. With effort, a bard can make the first verse of an old magical tune and mixed with different materials could shape aspects of the spell.

Without any material components the spell stays in its basic but useful form. The caster can target any object or creature; ally or not that is 8x8ft cube or large in size and that you can see within range.

Basic Form (No material Components) : The target if not willing must make a Strength Saving throw against the caster's DC or be mostly encased in thick hardened clay for the spell's duration. Being encased, the target becomes restrained but it gets a +4  bonus to AC.  The target becomes free if they take more than 5 points of damage in a round. The target can attempt to break free by using an action to make a Strength Check against the caster's DC.

Blood Earth(1 point of self-damage) : The target if not willing must make a Strength Saving throw against the caster's DC or be mostly encased in red thick hardened clay for the spell's duration. Being encased, the target becomes restrained but it gets a +2  bonus to AC. The target becomes free if they take more than 10 points of damage in a round. The target can attempt to break free by using an action to make a Strength Check against the caster's DC. However, at the end of the target's turn, they heal 2 points of HP as long as the Blood Earth encased them.

Chained Earth(5gp 10ft chain that the spell consumes) : The target if not willing must make a Strength Saving throw at disadvantage against the caster's DC or be mostly encased in heavy solid stone for the spell's duration. Being encased, the target becomes restrained but it gets a +5  bonus to AC. The target becomes free if they damage. The target can attempt to break free by using an action to make a disadvantaged Strength Check against the caster's DC.
