Corpse-Hunting Briar Tree

is a thorn-based Creation Magic spell.

Description
The users would open their grimoires and unsheathe their weapons in order to activate the spell. Once activated, the users' weapons, such as a sword, would transform into several vines filled with thorns. These vines would extend into considerable length as they surround the users.

These thorny vines would then actively hunt the users' targets. Once these vines have caught them, they would then converged together and rise to create a tree of thorns while the targets are still trapped between the said thorns. Additionally, the users could create multiple number of these trees as such that they are able to defeat a large number of opponents at once. These thorns are sharp enough that they could shred the targets that are trapped within them.
