Like that recent thing where people were talking about how a Halo map used a single rock in it, just scaled and rotated in different ways. Clever recycling of assets happens all the time and people never even notice. Even in the trailer for Shadow of the Erdtree, you can see they reused some model rigs - like how Messmer has the same standing idle pose as the Cleanrot Knights (though knowing FromSoft, there’s probably some lore implications behind it).
Though, if they make us fight a pair of Ulcerated Tree Spirits in a Scarlet Rot room or something, I might have some unkind words to say…
