Cicero (legendary joker)

[mortal tendon]

Upgrades the rarity of the joker to the right after defeating the boss blind.

Basically makes a random joker with higher rarity in exchange for the current joker. If its a legendary joker then nothing happens. Also incompatible with copy jokers

[regal merlin]

seems very op, but if it couldnt make legendaries, then it feels kinda underpowered
