Resurrection Shrines are identified by the red glowing flame in their center, and can be found through out adventure areas. They are generally are accompanied by a Rest Shrine. If you die, your soul stone will need to be carried by a party member to a shrine where your ghost can click the Resurrection Shrine to be brought back to life.
You can also attempt to make your own way to a shrine as a ghost if you die close enough to one. If you are not close enough to a shrine, you must release and you will resurrect at a spirit binder. They are usually located in a tavern. You must speak to them and 'bind' yourself to their location.
