As we all know, upon reaching the Sanctuary at the end of a SL you gain the correspondent mat and Echo Stone, as well as access to the Sanctuary alch machine. However, the mats themselves are tradable, so if someone wants all the SL armor sets and doesn't mind buying all the mats needed, that person could theoretically make all the SL sets in one SL run.

I understand that this is a valid and accepted way of obtaining SL sets, but I still feel that you should do a particular SL before reaping it's rewards.
I stewed over this for a few days, and came up an idea.

Have a SL-specific token trader in the Sanctuary.

This token trader would only sell the token items (detailed below) corresponding to that specific SL, meaning Frumious Fangs for UGW, Almirian Seals for UFSC, etc.

All of these are 5*

Ok, now the items:

UGW:
Snarby Gun (Barbarous Thorn Blaster? Dark Briar Blaster?) (50 Frumious Fangs)
I realize that there are already a few threads circulating about this, but this is my personal take on it.
I see the Snarby Gun is relative to Valiance the same way DBB is relative to Nitro.
Basically, a pure-piercing Blaster with slightly slower bullets and an additional effect.
I'm kinda on the fence about whether this effect should be:
1) Staggers enemies with each hit or
2) Dodging enemies won't dodge these bullets
Charge is the same shotgun thorn blast as BTB, but with more thorns and longer range

UIMF:
Oiler Set (Vitrolic Set?) (40 Bark Modules per piece)
Essentially the Quicksilver Set, but with Fire instead of Shock resist.
And instead of a low movement speed boost, perhaps an elemental resist? (Maybe around a High or Max UV)

URJP
Ice Queen Scepter (50 Jelly Gems)
Now what kind of ruler would you be without the signature ornate whacking stick?
3-swinger with normal/pierce damage
Charge is faster version of Triglav's with chance of Strong Freeze

Ice Queen Core (50 Jelly Gems)
With such an unstable personality, it's no surprise her core is the same
Pure normal bomb with a radius in between that of a 4* and 5* blast bomb
Does less knockback than Nitro, but has a chance of Strong Freeze as well

UFSC
Corrupted Crest (60 Seals of Almire)
This Crest of Almire was initially possessed by a spirit, then later cursed, gnawed on by a Carnavon, and used by a Cursed Dreadnought as a impromptu Caribbean steel drum. The spirit inside is understandably annoyed, and this shield radiates malice.
A Crest of Almire with Curse and Stun resist

TL;DR A Brinks in the Sanctuary with SL-specific items

Whew, that took a lot of typing
So, constructive criticism, additional suggestions/tweaks, and witty flaming/trolling are all welcome.
