Windward

You turn your body into the form of the wind, loosing all physicality and all influence over the physical plane. Without a body you cannot be hit but can also not attack or target any creatures. The spell lasts 1d20 hour(s) and cannot be cancelled before that point, you cannot be targeted by any spells, including remove curse or any other form of shape shifting or curse removal spell including wish. You do not remain sentient for the duration of the spell. After the spell duration ends you roll 1d100:

1. You Die, your body parts reform scattered across the countries of the world.
2-5. You reform incorrectly taking 100 (10d10+40) necrotic damage, A few major body parts are missing or others aren't correctly attached in the wrong country.
6-10. You reform badly taking 50 (5d10+20) necrotic damage, one minor body part is missing in the wrong country.
11-15. You reform well, in the wrong place, in a country separate to the one where the spell was cast. 
16-25. You reform well, in the wrong place, reforming 1d100+50 miles away form the location of the spell cast.
26-50. You reform well, in a nearby place, reforming 1d20 miles of the location away from the location the spell cast.
50-99. You reform fine, in the correct location.
100. You reform better than ever before, ageing backwards a year as well as for a day gaining advantage on every roll you make, this effect stops at the next long rest.

If cast at higher levels you add +10 to the result of the 1d100 for the result of reforming, this does not apply if you roll 1 and does not give the effect for rolling a 100 if your result is equal to or higher than 100, for each level over 5th.
