Frustration

Suesebron has about 50,000 breaths. And Lerasium is from Mistborn. I mean that's theoretically possible

A large amount of investiture will stretch your soul, which is why you see Savants. However you seem to have a misunderstanding, no person following the basic pattern of a magic system will ever ascend. A shard holds 1/16 of all the investiture/matter/energy in the entire cosmere. Even to get enough to come even close to being able to seem like a Shard you would need so much investiture it's not even funny. For Breath this would be in the Decacillions, maybe even higher For Spren this is likely in the hundreds of thousands of bonds if not more. Lerasium is a bit different as it gives connection and investiture but you still need enough to become a savant, so at least a good month of non-stop burning And even if you did get a lot of investiture you would never become more than a sliver, investiture is not enough you need a Connection to the Shard in particular.

Voidlight was braught over from Braize, from his conversation it sounds like it was drawn to him. Anti-light we know He did not neccesarily travel to Shadesmar. He was part of multiple Secret societies We already know that that is insufficent to become a CS None of those have enough investiture, with the possible exception of breath but even if Gavilar had some he did not have enough.

It's the color symbolism they have in the books

It would be possible, A bit early though I think we'd have to wait for era 4 Mistborn to see that.

I don't think it's the spren themselves so much as their Shardblade forms. In the CR they can just attach it to their bodies, Shallan just attached it to Pattern But the Shards themselves are too invested to lash

How was he invested enough?

Not even close There are only 16 shards no more no less. It's not the amount of investiture, it's the shard. Bound to what?

What they were saying is that not being able to bond again is what they thought had happened by sealing BAM. Mishram was pushing towards Feverstone keep. Radaints were fighting the front lines. Doesn't give a whole lot of time for wiggle room.

Unrealistic that none of the Windrunners could have broken their oaths in the time of at MOST a few hours between BAM's binding and the Recreance? Really?

He was able to learn from Melishi, and remembered that, I don't think he would be so ignorant as to not realize.

That is not the case, Ruin is about breaking things into their most basic forms

Surge Binding isn't Voidbinding, nor was Ashyn's magic garunteed to be Odium's. The entire Star system is invested, so Ashynite magic very easily could have been Honor and Cultivation. And for why Fused can use progression, Surgebinding is closer to Honor than Cultivation, if they had access to a corrupted version of Lifebinding they likely couldn't use progression

Ruin claimed he gave life meaning

Well hatred isn't exactly constructive.

I don't think Odium has a truest 'surge' so much as a truest 'Void' which would likely be the Voidbinding equivelent of Division.

I am not aware of anything that said that, could you provide quotes?

The Stormfather was aware of Ishar and Melishi but did not compare the two. Parshmen predate Ishar and even the ability to bond Surges by several thousand years. And so does the Nahel bond And the Sibling was Created by Honor and Cultivation.

It's a fight to the death

@Inquisitor #5 we know from a number of sources that every single Honorspren was bonded

Yes that's how you make deadeyes.

Of course

We have confirmation the bondsmith spren are Stormfather Sibling Nightwatcher Now they might be the closest Unmade to a Bondsmith, even though it isn't perfect and would likely be even closer to one of the other orders.

They say early on in RoW that you can stab spren with a blade and they will disipate before re-forming later.
