• Casting Time: 1 bonus action
• Range: Self (15 foot radius)
• Duration: 1 minute

You press your open palm to the ground, fingers extended. Purple glyphs form a circle with a radius of 15 feet centred on your current location. Each foot that a hostile creature moves through the area costs 2 feet of movement. Planar and ethereal travel is impossible while in the circle and invisible creatures become visible as long as they remain in the circle.

Alternate form: You can instead, as an action, inscribe a single glyph of Yrden on the ground which remains for up to an hour. Any creature that steps on the glyph must make a Wisdom saving throw or be stunned for 1 minute. The creature can repeat the save at the end of each of its turns. The glyph is barely visible and requires a successful Intelligence (Investigation) check against your spell save DC to be found.
