As you zero in on the glow in the cart, you see the faint outline of what appears to be one of the outfits Gwen picked up in the cave. Everything is bouncing around so much, you can't discern too many details, but after sifting through the supplies, you stumble upon the small sized shirt which glows with a faint aura.
The shirt, much like the wand, is an unassuming garment, albeit made of a high quality and sturdy material, except for the odd presence of fine, gossamer threads woven randomly into the fabric. It is unclear what this shirt is capable of, but it is evident by the fact that the pale glow is more radiant around the gossamer thread that those threads are the main source of the magic.
Continuing with your search, you notice the breeches that come with it also glow, and are made of the same material with the same gossamer threads.
Below that, you find a small cloak with a significant tear in it. The back of this dark cloak depicts a silver spear pointed downward. The glow around this article is similarly faint, and you suspect the magic on this one may be damaged from the tear, and frankly it's a small wonder the cloak possesses any magic at all with the damage that has been done to it. You know, from your studies, that damaged magical items can have unpredictable results. Some items, once damaged, can fizzle out at unpredictable times, fail to work at all, or even backfire.
The final article in this outfit are some strangely designed boots. These light blue leather boots have very thick soles, much like platform boots. They are made of incredibly high quality leather and are likely worth a small fortune by themselves. The color of the boots match the color of the thread used in the shirt and breeches, and compliments the trim on the cloak. Their size, quality and cut indicates these boots probably went with the rest of the outfit, and either belonged to the son of a noble or a wealthy gnome or halfling.
Due to the cluster of auras in one area, it's difficult to discern the tell-tale color undertones of the Detect Magic spell that give away which school of magic each item comes from.
All said, it occurs to you that you have just stumbled on a small fortune of magical goods. As you sit back to ponder the plunder one of the four medium sized daggers that Gwen found slips out from the pile of loot. Its gray, desaturated look indicates that it is non-magical, but the design of this magnificent blade suggests otherwise. Perhaps it was a magical item, but its potency had been spent or lost through time. Still, it's a sight to behold. It appears to be a finely-crafted dagger, with a hilt made of antiquated silver. The hist is fashioned like a serpentine dragon, with the eagle-like talons forming the crosspiece and the blade itself acting as a tail. Ruby eyes glean in the dragon-headed pommel.

Your minute is up. You may try another Spellcraft check (DC16 per item) when you can cast Detect Magic again. I'll give you a +1 to Spellcraft on your next check for the wand, since you were able to narrow it down to a few possible schools of magic.
