Crystalline Death

Crystalline Death gives the caster the ability to trap any being in a giant crystal rock, and with time, kill them. The caster must throw the components at a target using one action, and the target must make a dexterity saving throw. If not, they slowly become encased in a giant crystal over the course of the caster’s two actions, during which they must keep their concentration. Once complete, the target is fully enclosed in a giant rock shard, similar to one of the smaller shards’ shapes. The target is restrained, but alive and can breathe magically inside the crystal, frozen in one position. This trap does not stop or slow any kind of poison, disease, or other effects on the target. If the crystal takes enough damage, it can be broken, but the crystal has 100 hp and an ac of 16. If the crystal’s hp drops to 50 or below, the target can make a strength ability check to escape(dc 19) whenever the crystal takes more damage. However, 6 hours after the crystal’s creation, the shard starts to lose its magic and becomes filled with the glass shards inside. The target must make one final strength saving throw to break the crystal or die of suffocation. The glass component can be removed to avoid the lethal effect, and the crystal will immediately break at the six hour mark, freeing the target. Similarly, number of shards in the components depends on the target’s size: 1 shard for tiny, 2-3 for small, 4 for medium, 5-7 for large, 8-16 for huge and 17-20 for gargantuan. The number of shards used can increase the target number, depending on the dm’s decision for number of targets available. If the number of shards is any less than the requirement, only the target’s lower half to foot height will be trapped, and can be escaped with a str saving throw, dc 10. The caster can also end the spells effects whenever they want, freeing the target.
