Virtuoso's Awestruck Snare

You have the touch of a star and all things must become your audience.

You toss some debris and it plants itself into the ground acting as traps and becoming invisible, being seen by only the caster or by anyone with true sight. These traps have an Armor Class of 4 and have 4 Hit Points.

The trap has a 5 feet radius and trigger whenever an enemy walks on top of them. When an enemy walks onto the trap, the trap expands to have a 15 feet radius and halves the movement of all enemies within it's radius. After being activated, the trap takes one round before exploding and dealing 4d4 force damage.
