Dark Wood Seal

The spell summons pieces of a blighted tree to begin the sealing process to the target at hand. The creature makes a Dexterity saving throw, on success the creature is immune to this spell for the next 24 hours. On failure, the target begins the process of being sealed away and is restrained for the duration of the spell. At the end of every round the target may make a Wisdom saving throw to break free from it. Every 4 rounds after the initial casting, a new condition is put on the creature. The first of the two is the paralyzed condition, and the second is the incapacitated condition. If the creature is immune to any of the conditions stated in this spell, the spell bypasses those immunities. After the full minute duration has passed, the target becomes permanently sealed away, and can never be freed, except by a deity.

Once the process has begun, the caster has their movement speed set to 0 and cannot take any further actions until the spell is complete or the target breaks free. If the spell is completed and the target is permanently sealed away, the caster can never cast this spell again, unless the target breaks free from their sealing.
