Circle of Horrors

Druids of the circle of horrors are often considered a rather controversial and unorthodox kind of druid. Their members believe that sometimes to defend, protect, and enforce the will of the natural world that they must harness the powers in otherwise unnatural combinations, similar to how some monstrosities have been known to be made, these druids firmly believe that the ends justify the means, being one of the circles even willing to consider and use metal based shields and armor, but tend to not do so unless it is absolutely nessissary.

This form lasts for 10 minutes. It ends early if you dismiss it (no action required), are incapacitated, die, or use this feature again.

When you activate this form, and as a bonus action on your subsequent turns while it lasts, you can make a ranged weapon attack, hurling a pointy spine like quills that targets one creature within 60 feet of you. On a hit, the attack deals piercing damage equal to 2d6 + your Wisdom modifier.
