To be honest, i completly don’t get how a 23 years old male can ask for an even younger Vessle!!
Get the vessle you have, fixed!
ask again when you’re somewhere between 60 and 99.
Besides, true Full Body Adoption, means to DIE!
Becouse you leave back your old vessle without any Spirit, and therefore unable to sustain life.
And your own Essence would be much to busy fighting the Spirit of the Body out, that you posses.
So, seriously, my advice is, life before you ask for a New life.
'Couz even for the oldest and most cruel creatures, that step isn’t one to take lightly!
- Personal opinion tho.
