Currently the herder credo buffs only apply (or so it seems) if the person with the credo is the one to do the branding, you can't just craft a branding iron and share it about.
I propose that's changed so its the branding iron itself that applies the buff if its attuned to somebody with the credo.
The credo is an absolute pain to get to, especially if you have unlocked literally anything else with the way credo quest count scales. Its current version incentivises bots honestly.
Theres probably better suggestions to be made, but idk. I'm only logging in now to check on scholar progress (i'm currently 70 days into scholar, this is far too long for a credo). I was making an alt to try and get the herder credo but honestly, Nomad is so beyond boring to do, I can't actually be bothered because the only thing left for me to do this world now is grind. idk, next world i'll likely make a bot to herd animals and just share an account with my group to get herder on it early rather than having certain people maintaining animals because nobody can be bothered with that monstrosity of a task anymore.
