Kelleflump's Irritating Demon

What's it called? Kelleflump's Irritating Demon (in short, KID)

What does it do? A young daemonologist's handy helper, this spell should invoke a little, annoying and perky deamon (the small version of the other Kelleflump spell) that makes your fighting enemy lose concentration and suffer some very modest but interesting pain over time.
Its biggest setback isn't the small amount of damage it does, but rather the fact that you need a twisted black amulet to cast the spell. After some uses (variable, and depending on your castings skills when you made the said amulet with the appropiate spell) which don't usually exceed 10 or 12 at best, it will melt away and cause some freezing hurt, and the need to get another amulet to continue hurting others.
If it weren't for the amulet, the spell would be useful, specially for troll-finishing, as it ignores their skin. As it is, I don't tend to use the Irritating Demon much...

Where is it? Being one of the most recent additions to daemonologist lore, it is only fitting that it should be at the furthest book from the library entrance: the 'My Firste Demon-Summoning Booke! By Beatrix Faust' grimoire, at the Unseen University.

What does it require? It has already been mentioned: a twisted black amulet. And a knife, which isn't consumed (usually a handy dagger does the trick). A nasty mindset is quite optional, but fits the job (and cackling madly).

What skills do I need? Summoning, Cursing, Conjuring, Divining

Has it worked? The proper output should read something like this:

You prepare to cast Kelleflump's Irritating Demon on xxx.
You move your knife in an arcane gesture, slashing open the boundary between this dimension and the One Beneath.
Intoning a long string of ugly-sounding words that scratch and tear at your throat, you place the Mark of Unearthly Perdition on the xxx's brow.
You reach into the rip between the dimensions, and drag a small black demon into this reality between thumb and forefinger.
You reach out to the demon while it flies towards the xxx, all claws and warts and wide-open jaws, and establish a connection with its foul unearthly mind in order to share its delight in your victim's pain.
The xxx stiffens and then contorts in terror.
