LERASIUMMMMM

[Denissimo He/him]

What happens if you take more than one bead of Lerasium?
Any negative effects? WHAT HAPPENS?
At one point, BS was asked why Hoid didn't take 2 beads of Lerasium, and he answered that it was because he knew if he did, bad things would happen.
WHAT BAD THINGS???
Also, what would happen if a shard ingests their own Godmetal, or another Shard's godmetal?
MORE SPECIFCALLY, If Ruin had eaten lerasium and leras eaten Atium, what would have happend?

If a Mistborn burns Lerasium, they become a stronger Mistborn.

Because Hoid has some future sight ability that gives him directions, and if he had taken that second Lerasium bead, then Elend would have died and Vin would not have been able to save Scadrial from Ruin.

Ruin would have needed to manifest physically to absorb the Atium in the Trustwarren to regain his full power.

And considering just how polarized Ruin and Preservation are, either attempting to assimilate the power of the other, without being Harmony, would probably backfire and harm them.

Thanks! Good answer.
Any weird effects if someone just consumes Lerasium in copious and ridiculous amounts?

Not necessarily. We don't know the Allomantic effect of Lerasium yet - we have not seen it on screen and Sanderson has RAFOed the question.
We do have this Annotation/WoB:

Chapter Thirty-Eight

Preservation's Power

All right, so maybe I lied about there only being three magic systems in this book. It comes down to how you term the powers of Preservation and Ruin, who kind of blanket the entire system. There are a lot of things going on here, and—well, the truth is I don't want to mention all of them, for fear of spoiling future books. However, I'll give you a few rules to apply.

First, to these forces, energy and mass are the same thing. So, their power can take physical shape—as Preservation's did in the bead of metal Elend ate. Second, there is a bit of Preservation inside of all the people—and it's this that allows the people to perform Allomancy. It needs to be awakened and stirred to be of use, but when it is, a proper metal can draw forth more of Preservation's power. It's like the metal attunes the bit within the person, allowing it to act as a catalyst to grab more power.

Allomancy is not fueled by metal; it is fueled by Preservation. The metal is the means by which a person can access that fuel, however. If there were another way to access it, then the metal wouldn't be needed.

Preservation's touch on people differs. Some have more, some have less. This doesn't make them better or worse people—indeed, some most touched by Preservation have been among the worst people in the world. As Ruin later points out, there is a difference between being evil and being destructive.

Regardless, if a person can get more Preservation into them, they become better Allomancers. Hence Elend becoming a Mistborn. Like all people, he had the potential within him—it was just too small of a potential to be awakened through normal means. That little jolt of Preservation's body, however, expanded and awakened his Allomancy.

As a tidbit, that was a side effect of what that bead of metal did. It wasn't the main purpose of the bead, and if another Allomancer were to burn it, it would do something else.

The Hero of Ages Annotations (Nov. 12, 2009)

Creating Mistborn is a Side-effect of Lerasium, when burned by a non-Allomancer. Not the true Allomantic Effect of a Mistborn burning Lerasium.

A Lerasium Savant would Ascend to the Shard of Preservation. It's basically what Vin did with the Mists, since the Mists are just the gaseous form of Preservation's Investiture, with Lerasium and the Well of Ascension being the solid and liquid versions of it.
