Siren Song

All enemies in range must make a save against your Potency. If they fail, they may only spend AP on their next turn to move closer to you using the most direct path possible and cannot make attacks before that. To move closer, they may take actions that would help in getting closer such as standing up from prone or using fae flash. 

If this path leads them through an obviously harmful hazard such as off a cliff, they are no longer affected by this ability. Otherwise, this ability lasts until they are within 5ft of you or until they take damage. While playing this Song, you can take no other actions. Taking any other action cancels the Song, immediately freeing all enemies from its effects. A creature can only be affected by this ability once per encounter.
