The Fellspine Mystery

[Teppler]

Which was the siren's grotto seahorse that spawns the fellspine at a higher rate?

This something I've been intrigued and asked about a few times over the past couple months but never get an answer. This is my last shot, asking directly.

I believe a couple guys noticed after server resets a certain spot spawns fellspines more, they farmed the hell out of spiked seahorse belts and it got nerfed.
