The only effect of adding marloss stuff to mutagen would be to completely neutralize it.
And there won’t be any fungal mutations either.
But there WILL be more interesting other fungal stuff added.[/quote]
Righty-ho. We’ll disregard that marloss berries have a pretty good shot at either mutating or purifying the PC, as well as making them a Carrier.
I’d presumed that concentrating the marloss would be a good way to ensure Marloss Carrier. For factions whose goal is spreading fungus, creating Carriers would be a logical move; multiple carriers with fewer berries/carrier would nevertheless spread the fungus farther, faster.
