Bit of an outlier, but has anyone tried converting 4E D&D characters to Godbound?
Short answer (to my knowledge): No and I'm not sure anyone would ever see a reason to.
HOWEVER! Long answer: I've long pondered the possibility of looking into the immortality-unlocking Epic Destinies for inspirations for Godbound material.
I have a campaign with level 28 4e characters. Considering a godbound campaign to follow it. Conversion would be pretty simple just eyeball some words to match up with class/path/destiny - the dwarven priest of moradin gets artifice, earth and health. The half-orc rogue goes for alacrity, deception and sword and so forth.
