This question already has an answer here:
I've looked over multiple different questions, and they either dealt with something similar, or gave frustratingly vague answers. So I'm certain that my question is not technically a duplicate (though by saying this I have likely doomed it to being labeled as one).
What are the 'powers' of the twenty Rings of Power? For one thing, the One made its wearer invisible and quasi - immortal. The Nine, I think, made their wearers invisible only when they chose to be when they were still human. But that's all I know about their powers.
I'm not asking about their corrupting influence, nor am I asking about what was done (for example; The Seven let the Dwarves build their wealth but made them greedy, I get that, but how did those rings increase the treasure troves? Did they generate gold? Did they make the Dwarf Lords just that lucky when choosing mining spots?).
To reiterate my question, what powers did the rings give their wearers?
