Whether by accident or by design, you have been infected with a fungal curse originating from the underground city of Spire. You have not found a way to remove this curse on yourself and it has slowly drained your strength over the many years since it entered your body. After encountering a Shard of Nivar, you feel that there may be a possibility way to curb the worst effects of this curse by calling on the magic of the shard.

Once per Long Rest, you can momentarily pass some of the effects of your curse to another creature within Melee range. Mark 1 Stress to weaponize your Fungal Curse to make the target temporarily Vulnerable and have Disadvantage on their next role.

During your next Long Rest, start a Countdown determined by the lower number on a duality Reaction roll. As a downtime move, you can tap into the power of the Shard of Nivar in order to attempt to purge the negative effects of the Fungal Curse from your body. Roll an Instinct Roll against the DM’s determined difficulty, and, on a success, reduce the countdown by 1. When the Countdown reaches 0, consult the GM for effect.
