Trapping Web

You shoot out a 15 foot wide sticky and explosive web to a target area within range and cover the 15 foot cubed area with the sticky and explosive web. Any creature within that 15 foot target area must make a Dexterity saving throw against your spell save DC and on a fail are restrained by the web. On a success the creature is not restrained but the web stil covers the targeted 15 foot cubed area at the targeted area and is now difficult terrain. If restrained, the creature can spend an action on its turn to make a strength saving throw against your spell save DC in order to break free and on a success is no longer restrained.

These webs last until the beginning of your next turn after you have cast this spell. At the beginning of your turn the web explodes and disappears and any creature or object at or within 5 feet of the area of the web takes 4d10 bludgeoning damage. Targets restrained by Trapping Web lose the restrained condition after taking damage. The webs are flammable and if they are hit by any type of fire damage then they immediately trigger the explosive effect of the web.

When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d10 for each slot level above 4th.
