I'd fucking kill for some system where you can spends Murks and/or Sigils to upgrade and reroll relics:
>1,000 Murks to upgrade a Delicate into a Polished relic with a random effects rolled
>5,000 to upgrade a Polished into a Grand relic with a random effect added
>10,000 to alter the relic into a random color (could be the same)
>50 Sovreign Sigils to reroll a relic ability of your choice to a new one
Opinions? I think it should be costly to manipulate them in this manner, but I still think it's better than just hoping for God rolls.
