Either you a go to the spirit healer and take damage to your stuff
or you can march back to your body.
or you can glitch out of an instance. What you do is you die *DONT RELEASE YOUR SPIRIT. Then leave your party a message should pop up[ say ing you are no tin the instance group you will be teleporeted back to *Name of CIty* in 60 seconds. let the time run out and you ll be teleported to the city it will instantly rez you with full health. and you will have no res sickness nor will you have any damage to your weapons.
