Tripwires

You create a few ethereal tripwires in a 5ft cube. This cube does not need to be touching any objects, walls, or the ground and can even be entirely in the air as the tripwires' ends are fixed in space by ethereal anchors. However, it cannot be placed in the space of another object or creature.

The tripwires are camouflaged to look almost invisible. Any creature of size Large or smaller must make a Wisdom (Perception) check against your spell save DC to recognize the area as hazardous before entering it. When a creature of size Large or smaller enters the area without being aware of it, they must succeed on a Dexterity saving throw against your spell save DC or fall prone. If they have recognized the area as hazardous either by succeeding on their Wisdom (Perception) check or having already attempted a Dexterity saving throw for this area, they can treat this tripwires area as difficult terrain and do not need to attempt another Dexterity saving throw when entering its area. Creatures of Huge or larger are unaffected by this spell and destroy the tripwires when they enter its area. Any creature may spend an action to destroy a tripwires area the creature is aware of and can touch. The tripwires can have one of the following magical effects:

• Extra tension is added to the tripwires causing the tripwires to collapse around a creature when triggered. The first creature to fall prone takes 1d4 force damage, then the tripwires vanish. Otherwise, the tripwires last for 1 hour.
• The tripwires are strengthened. The tripwires last for 1 hour and can cause any number of creatures of size Large or smaller to fall prone.
• Instead of your spell save DC, the area is recognized as hazardous with a Wisdom (Perception) check against a DC 0. In exchange, this cantrip can be cast as a bonus action instead of an action. The tripwires last for 1 minute and the first creature of size Large or smaller to fall prone causes the tripwires to vanish.

If you cast this spell multiple times, you can have up to 2 effects active at a time, and you can dismiss a tripwire field as an action or a bonus action.

At Higher Levels. The number of effects you can have active at a time increases by 2 when you reach 5th level (4 effects), 11th level (6 effects), and 17th level (8 effects).
