Ring of Alertness
You have advantage on Wisdom (perception) checks & Rolls for Initiative.
While wearing ring you can use action to cast:
1x day. Recharges at dawn.
I really do try to make most of this original, but since Forgotten Realms is an integral part of the world I can't help if anything is used without formal permission, but is still "fair use" as I am just using this for my private games.
