18th Shard

Poison dart frogs launcher. Check and mate.

They use the gemhearts to Soulcast food, probably. They need the gemhearts to survive the siege because gemhearts are the only way to provide food for such a large army.

What burning a metalmind does is not burn a new metal with an Allomantic effect. When burnt, a metalmind allows you to use the extra power inherent in Allomancy, but instead says, "Please put the power into (attribute) format," so it is identical to Health. You wouldn't need to "compress charges", only get another metalmind. The Feruchemical charge is like a filter, not changing the fact outside light (power) is passing thru, only changing the color or form.

I think if you stab yourself with a piece of metal and leave it in, you're dead. You just got stabbed with a piece of metal. If you take it out and put it back in, maybe you'll survive... maybe. Just because you have a spike in you doesn't mean it's a Hemalurgic spike.

But were those piercing his skin? I can't remember if they were or not. As an aside note, if you need a super high amount of power to pull on a Shardblade... well, in Compounding Mechanics, I thought of Compounding the power of DURALUMIN. Super-duper Duralumin fueled Steelpush. Bwahahahaha!

I would also like to add that all these Compoundings could be used in a cycle. I store Allomancy, burn metalmind = duralumin power without the duralumin.... Actually, what would happen if you could Compound Duralumin this way. Super-duralumin boosts...

I was thinking that the original types 5 and 6 were forms of Compounding via Hemalurgy. So you could share a metalmind or Allomancy, but only to a point. It's more efficient as more than one person can draw on the ability without it being only one person at a time. However, being end-negative it probably loses power.

Exactly

Who better to be a king than one with the Herald's own Blade? Passed down through the family. Plus, maybe Gavilar didn't bond with the Honorblade. Dalinar "bonded" with Oathbringer, didn't he? Do you have to bond with every Shardblade and how does this work?

I was looking at known ways Surgebinders use their Surges. Kaladin and Szeth: use the Basic, Full, and Reverse Lashings. Jasnah and Shallan Soulcast. Lift increases/decreases Friction, Grows things, and uses Regrowth. Then I thought, what if all the orders have three lashings: one from Surge 1, one from Surge 2, and bonus Lashing 3 that's only used by their order. The Basic Lashing is the gravity Lashing, the Full Lashing is the Atmospheric pressure, Lift's sliding/climbing is the Friction Lashing, growing seeds is a use of the Growth Lashing, and Soulcasting is the highly diversified Lashing of Transformation. The Reverse Lashing is the Windrunner Order Lashing , and Regrowth is the Edgedancer(?) Order Lashing. Perhaps Lightweaving (making Illusions) is the Lightweaver Order Lashing. This would put the number of Lashings at 20. The Surge Lashings directly affect the Surge (Basic lashing affects gravity, full lashing affects atmospheric pressure, Soulcasting is the Transfromation, Sliding/Climbing directly affects friction, Growing Seeds directly involves growth, etc.). The other lashings are less directly affecting their surges (how is Regrowth directly affecting Growth or Friction? It heals, not grows something, and friction...)

By the way, I love the names synergisers and souleaters. +1 for you

I still think you would be able to store the Allomantic attribute. Yes, they have to be able to store the ability, but they are already a Ferring of that metal (see Conjecture 5). This should give them this ability. As for entropicsscholar's ideas, I think Hemalurgically-powering Allomancy means somehow, you store x amount of time's worth of burning, say, pewter in a spike. This spike can be passed along until it runs out of that amount of time, at which point it reverts to being a useless hunk of metal. Feruchemically-Powered Hemalurgy is not storing something in the spike, it is storing the spike's power (so if it were a Pewter spike that stole Feruchemical gold, storing the ability to store/tap Gold) in a metal mind.

I'd like to restate what Vortaan said. Something should be attracted to him: angerspren, painspren, etc. but they aren't. As far as we know, most spren can't choose to be invisible. They can't choose in general. Only spren that have bonded with someone have shown any kind of ability to choose whether or not to appear. Szeth should have spren exploding around him with the emotional trauma and pain he feels as he kills, yet he doesn't.

I was thinking, even if you have your whole army a mile away and a couple of scouts with flags to tell you where to point your spears, you could have an army that fights with out having people be killed. 200 guys with fabrial-spears stabbing from a 100 yards away is going to more damage than 200 spearmen up close. Yes, energy is conserved, but with enough men, you could potentially do a lot of things that would be devastating to another army.

What if you used the fabrial with rubies - the one in spanreeds - and attached one side to a stick in your hand and one to a sword. Repeat with multiple swords, but on the same stick. You then turn them on with the swords by the enemy, swing. Your swords will now attack without a wielder. You could make a giant wall of spears, with no one to kill to knock down the spears (you could still cut the spears, but still!). Any other awesome uses for fabrials?

Szeth doesn't seem to attract bindspren with his lashings, nor any spren at all. There are two ways to explain this: Shinovar doesn't have spren and Szeth is fom there, or ... just as the mists stay away from hemalurgists, the spren are staying away from something of Odiu's, whether it is the Surgebinding, Blade, or the Dark Sphere from Gavilar. Thoughts?

Waves, crested white, create splashes, fall down falls, splashing, create white-crested waves. Stars, shining, to darkness fading -changing winds changing- fading darkness to shining stars.

I think there is alot to be said about the reason they use spheres is because they could hold stormlight. On Scadrial, atium (not by chance) is a form of currency mainly due to its value Allomantically. This could be true of spheres, too.

Is it necessarily gems, or is it stone in general? I know there isn't much evidence other than the Shin's dissaproval of 'stonewalkers' and thinking stone is holy. Actually, thinking about it, that could add to the gemhearts theory. They respect stone because it "grows" gems. Hmmm.

I don't know if this has been adressed elsewhere, but has anyone noticed that in the arches at chapter headings, there are the 10 heralds(probably)... and that random guy with a mask? Who is he? I think it either is an evil bad guy we don't know yet (an Unmade) or Hoid. Each chapter it is shown, Hoid appears in. In fact there is only one chapter he's in that the masked figure is not at the start of. And the interlude with double Masked Guy, that is all about three Worldhoppers loooking for Hoid. Thoughts?

Did anyone else notice the I think this implies he would be immortal (as in, not aging). Does something about Hoid make this ring a bell? Hoid has lived far longer than he should be able to.

I had some ideas about the different kinds of Compounding in http://www.17thshard.com/forum/topic/4633-compounding-mechanics/.

I don't think it would need to be different. From what Wax thinks of Miles, we can safely assume that Compounders are pretty rare. Even if you could figure it out, wuold there be any way or reason for you to tell others? When you burn a metal, it is apparently pretty obvious there are other power sources you could burn (from Vin's point of view). However, storing an attribute probably doesn't have a big obvious, "You can store Speed now...and now..and now.."You would have to be conciously aware that you could store your Allomancy, and have to be a twinborn type that is already a rare occurence.

I am going to agree with Darnam. If Compounding for Feruchemy only requires one to be a Misting and Ferring of one metal, why wouldn't it be the same for Allomantic Compounding?
