Several of Toria's past experiences absorbing magical and arcane lore would endender in her mind a relatively clear idea of just what the monocle did: after studying it with her divination cantrip, and then using<em>it</em>in her appraisal of the other items, she would realize that she could quite clearly identify the magics behind the halflings' other trinkets in turn. Their torso-chain, the vests they'd worn underneath, and the rings all granted complementary modicums of protection to the wearers (with the vests and rings being able to resize themselves for 'bigfolk', as most item of Art in Faerun other than arms and armor were).<br/><br/><br/><br/>Using the skill usage from MICp217:<em>A character using the detect magic spell can attempt a Spellcraft check to determine teh school of magic associated with teh item's powers. If the character exceeds the DC for this check by 10 or more, the chaacter magically divine the item's functioning, its means of activation and the number of charges remaining.</em><br/><br/>The DC referred to is 15 + spell level, aka 25 + spell level for IDing. It's not quite an Identify spell, but for most items it'll be enough to make use of a thing or determine it's uninteresting. And on the monocle (just transcribing the entire item description here):<br/><br/><br/><em>Artificer's Monocle (Magic Item Compendium, page 72)<br/>Price (Item Level): 1,500 gp (5th)<br/>Body Slot: Face<br/>Caster Level: 5th<br/>Aura: Faint (DC 17) divination<br/>Activation: see text<br/>Weight: -<br/>Putting on a monocle is a standard action. While wearing an artificer's monocle, whenever you successfully use your artificer knowledge class feature (ECS 31) to detect an item's magical aura or you cast detect magic and have at least 5 ranks of Knowledge (arcana), you can spend 1 additional minute studying the item. If you do, you can identify the abilities of that item as if you had cast identify upon it.</em><br/><br/>Since Toria has 5 ranks in K(a), and she tried using it to look at the other items, she identifies them as:<br/><br/>4x Small +1 chain shirts<br/>4x rings of protection +1 (aka +1 deflection bonus to AC)<br/>4x vests of resistance +1 (a bonus to saves)<br/>the handy haversacks are still just that<br/><br/>(Although the monocle description may not be entirely clear on this point, I'm assuming using it for a minute maintains concentration on Detect Magic, since using DM is part of it...so Toria can ID 9 items per cast of DM using the monocle. Even if she doesn't want to cast a 2nd one, it's probably pretty obvious what the other items of the 17 are since they're 4 of a kind. And-or it's not like she doesn't have slots to burn for a 2nd DM if she wishes.)<br/><br/>The nonmagical stuff with the monocles is a mw Appraisal toolkit (+2 circumstance on Appraisal checks.)<br/><br/>I provided the literal text of the monocle mostly as a convenience to myself - it brings up an interesting philosophical question: can the monocle be used to Identify itself? Toria doesn't<em>quite</em>have the knowledge of it as if she's cast Identify on it (the prereqs for crafting a copy of it, for example) - but via her DM and Spellcraft on it, and trying to use it on the other items, she has figured out how it works and what it does.
