Best candidates are probably physicians, since they can screw you up lategame. Only a great idea if alchemist has openly claimed really, since they are one of the few neuts that can side with you and topple the king, the highest obstacle for Possessor, and you do not want to jeopardize Alchemist’s claim space.
Drunks that have “happy houred” are a good one too, jump to whoever got “happy houred”. You never have to explain your night action and Drunks are likely getting executed. Drunks are really bad for you since they can detect redirect immunity, stop you from jumping and are confirmable with royal blood. They are a prime target.
Princesses are of the same breed that trip you up with their invest skills that can actually find a Possessor fakeclaiming and they can confirm themselves with royal blood.
Sheriff/Paladins cannot find you and are trying hard to kill the opposing faction, which works in your favour, never try to frame these.
Hunter is way too obvious early game and instantly everyone will know it is a possessor game. Mystic is the same. Noble is self-confirmable, so also a bad idea.
Knights and Observers are your friends with the way puppet strings works, so also no reason to get them on somebodies radar. Observer’s can be tricky though and find you, so it is not super unreasonable to frame them. Knights are one of your valid fakeclaim, so never cull them.
Butler’s have the same arguments as drunks, except no royal blood, they can poison king, which is the highest obstacle and they can be a fakeclaiming Sellsword.
Court wizard is iffy. The same arguments apply for the Knight, but you must get rid of them before lategame, since that swap can be deadly. Would not recommend this one either.
Never jump as a neutral either, cramping the claim space of fellow neutrals who can side with you is just rotten and typically you gain nothing. Inquisitor jump can also not happen N1.
Jumping as evil is just a big giant signal to the evil faction that HELLO THIS IS A POSSESSOR GAME. And possibly framing a Sheriff, terrible idea.
Same idea applies to Prince.
But honestly, jumping N1 is just terrible in my opinion. You will need these jumps when you are in a bind later.
