So, I need some ideas for a magic item. I have never created magic items before so this is all new for me. The game I am running, there is some ruins in the dark forest. Within these ruins is an artifact/magic item that is called The Heart of the Forest. The group told me it was up to me to determine if it was a weapon, potion etc. The ruins are in a forest that has gone dark due to a blight. The blight is believed to have been started by a druid. So, if anyone could help with ideas that would be appreciated.
