I am fine with making the Enrichment as part of the game, after we've joined the Covenant, but generally speaking, I have shied away from having Celeste gain much Vis. She only gained like 4 pawns over 6 years, and one of them she supposedly paid to get the Opal Enriched.
But if you see it otherwise, I will not fight you over it. It would be nice to have, but it's not a must have, or something Celeste can't live without.
