This is a mod for RoR2 that by default makes it so that each unique max eclipse level win increases all survivors eclipse level by one.
I made it 'cause i thought having to play each character 8 times for seemingly no reason at all was dumb. This provides a sorta elegant solution that keeps the original "prove yourself worthy on each character", but makes it less extreme.
Unique max eclipse level win means that you have beaten the maximum eclipse level(8 for vanilla) for the first time no matter whether this mod was installed when you did that or not.
Original game requires you to get 16 * 8 = 128 (!!) wins in order to get golden eclipse 8. With mods adding new characters this number only grows further and further.
With this mod using the optimal route (getting 8 characters to E8 in a row) you can shrink that number down to 36.
