Does putting points on the skill get a higher chance of reincarnating the bosses?
it’s also semi useless skill cause you can’t reincarnate bosses from ET/DGs, just salus 
Is reincarnating bosses from card albums also possible?
No, you can’t reincarnate those.
Its useless now. I thrice used it on glowing mob (items and silver), both mob died without any drop. Cant even use on bosses aside from Saalus. Hayyyy
Reincarnate is dead.
