Do all of the Sacred Treasures have a seal on them to restrain their true forms. Such as how Fireseal becomes a massive sword composed entirely of magical flames when Sol goes all-out?
At the moment there isnât enough information to say if they do or not.
Even with something like Flashing Fang, all we really know is that it was a âpartâ that was used to enhance the Firesealed Sword when Sol upgraded it.
We know next to nothing about the Baikal or Dominator, or even the nameless ones, to really say what theyâre fully capable of.
All we really know for certain is that each is potentially dangerous on its own, thatâs why the Conclave had many of them sealed away.
Furthermore we donât really know why the OutRage are connected with Gears in the first place.
The only real piece of knowledge stems from the Saint Oratorio Project, which Sol was originally going to be a part of a research team on.
Saint Oratorio is âtechnicallyâ the most powerful spell in human knowledge, so the OutRage are, by extension, meant to âcontrolâ the spell, at least from a technical standpoint.
But again, Saint Oratorio is basically synonymous with Gamma Ray: itâs way too powerful for any one person (human or otherwise) to safely control without limiting its output in some capacity.
And considering the destruction caused by a +40 max output Gamma Ray that destroyed Japan, leaving a gaping hole in the Pacific Ocean, any OutRage part is just as dangerous potentially, no matter how small.
Itâs about the equivalent of trying to understand the individual parts that make a Thermonuclear Weapon function.
With Sol progression with dragon install how much does he rely on the fire seal power in combat? Also has shown master over any other element besides fire?
Sol has fired off shots with the Junkyard Dog (thatâs the upgraded Fireseal by the way) that are strong enough to smash a Mountain. Â He also used it to kick-start the Saint Oratorio spell so it would effectively reboot Justice so that Jack-Oâ could complete the merge with her.
The Junkyard Dog Mk 3 likely doesnât have much directly to do with Dragon Install.
Although the sword transforms in that state in a kind of âcasing purgeâ, it isnât really tapping in to Solâs powers, but amplifying them, like most OutRage.
As for other spells, Sol has used a Float Spell, a âCrimson Jacketâ enhancement, and he uses a Summoning technique called âSoul Sinkerâ that Izuna taught him. Â Magic Com phones are also a common spell, as is Zeal used in Mana Engines like in Solâs Firewheel, which he summons.
Sol has a wide understanding of Magic Particle Physics, that how he built the OutRage in the first place.
So what exactly are the differences between the different "Mks" of the Junkyard Dog. We know MK III has Flashing Fang/Senga inside, allowing it to fire magic fire bullets and Saint Oratorio. But what did MKs I and II even add to Fireseal?
The âOriginal Junkyard Dogâ was Solâs fang-shaped  "concrete slab blade" that he put together during his self-subsistence days working in the Sacred Order.  It was more or less the âinspirationâ for later designs.

Around 2186, Sol made two consecutive âupgradesâ to the Firesealed Sword:

http://gear-project.tumblr.com/post/92741408719/
The latter upgrade eventually became known as the Junkyard Dog Mark 2, although powerful, it lacked output or energy control.
After raiding Harden Fortress, Sol obtained the Flashing Fang and used it to increase the Mark 2âs power output based on the functions of Saint Oratorio. Â This became the Mark 3.
The Mark 3âs power output can be Multiplied 5 times itâs initial power. Â Capable of smashing a Mountain.
Ky managed to dismantle the Mark 3, so Sol might have to reconsider itâs design later.
Sol has plans to recover the remaining OutRage, though itâs unclear if they will be fully combined, as the Thunderseal only just regenerated and the Zessen is still in Anjiâs possession. Â Slayer also holds a nameless one.
A look at the different levels of Fireseal buffs in GG2, and alternate Dragon Install Colors.
(As a side note, 100% Dragon Install uses Solâs default sword model underneath the huge sword of flame he wields in that form.)
Oh yeah, and apparently whenever Sol does his âidle animationâ in Dragon Install form, the model freezes because it doesnât have the idle animation to share the same motions default Sol has. Thankfully they added these in Xrd.

A little set of captures for an idea Iâm having... Just wait, youâll see the idea on Twitter soon...
It may be a question that has no real answer, but I'll ask anyway: What ever happened to that cool chainsaw blade that Sol had in Overture that was a part of Fireseal's new casing?
That was just a temporary design that Sol used when not using the Firesealed Sword.
When he rebuilt the Junkyard Dog, he probably took a few ideas from older weaponry heâs used to make it.
Was Fireseal's change in appearance due to Sol making modifications to it or did it reshape itself to better accommodate for his steadily increasing power?
Well, it seemed to work in tandem with Solâs Dragon Install in GG2, so, perhaps both are possible.
Though thereâs still much we have yet to learn about the OutRage and its true nature, despite being designed by Sol.
