Trapping bolt

With this spell you can target one creature or solid surface within the spell's range.

If you target a creature, you make a ranged weapon attack against that creature as part of the action used to cast this spell. On a hit, the target suffers the attack's normal effects, and it becomes surounded by white strings made from unstable energy until the start of your next turn. If the target willingly moves be- fore then, it immediately takes 1d6 thunder damage, and the spell ends.

If you target a surface, your projectile will attatch on the surface. When creature moves in 5-foot radius from projectile, the projectile will start glowing and emit dim light. If the creature willingly moves out of the radius, then the projectile release an shockwawe of energy, every creature 5-foot radius and the creature that trigered explosion takes 1d6 thunder damage, and the spell ends. Creatures that already were in radius don´t trigger the explosion.

At start of your turn you can start Concentrating on spell and extend its duration to 5 minutes.
