From D&D Wiki
|2nd-level Transmutation (ritual)|
|Casting time:||1 minute|
|Components:||S,M (Diamond worth at least 50GP)|
You attempt to touch one medium creature and entomb them within a crystal. Make a melee spell attack against a target creature of size medium or smaller. On a hit, the target is trapped within a crystal and is rendered petrified. Any attempts to discern the status of the creature will return that it is deceased. At the end of each of its turns, the creature may make a Strength saving throw, contested against a DC of 13 + your spell casting modifier. On a success, the creature is freed from the crystal and becomes incapacitated for one minute.
The crystal itself can be broken by external sources, having an armor class of 17 and 30 hit points. When the crystal's HP reaches zero, the creature within automatically succeeds its next saving throw against the crystal.
At higher levels. At 4th level, you can target a creature that is Large-sized. The spell can also target Huge and Gargantuan creatures at 6th and 8th level, respectively.
