Luring Light

In the darkest depths, there is always something waiting for the curious and the foolhardy to make one final mistake.
You create a lure of light at a point you can see within range while making yourself invisible. This lure creates bright light in a 5-foot radius around itself, and moves with you. Whenever a hostile creature sees this lure light for the first time, it must make a Wisdom saving throw. If it fails, it must use all of its movement during its next turn traveling towards the lure by the safest route possible. A creature that is immune to being charmed is immune to this effect. If a creature touches the lure, you can use your reaction to cause a predatory phantasm to lash out and bite the creature. The target must succeed a Dexterity saving throw or suffer 4d10 magical piercing damage. Once you use this reaction, or if you attack or cast another spell, this spell ends.

At Higher Levels: When you cast this spell using a spell slot of 4th level or higher, the piercing damage increases by 1d10 per spell slot level above 3rd.
