This is a study of the effectiveness of not the individual but a group of individuals. This is an Open Ended Plot which will not be fleshed out by a single person but by who ever chooses to add content.
The peaceful sounds of mid afternoon were brutaly interupted by the swears and jeers of a fight erupting on the edge of the market near an alleyway. Seeing three armored humans fighting a young boy, the fight seems a bit unfair. Not seeing anyone rushing to the aid of the elf and with no watch in sight, the elf doesn’t seem to have a chance. Cries of thief echo from the lips of the three humans.
These magical boots empower the wearer with several abilities at once. Wondrous leaping, water-walking, and even flying! Yet the boots possess an insidious curse upon them as well. A deep and almost unfathomable (by others) feeling of listlessness, boredom, and even apathy affects the boots' wearer at all times whenever they are donned. Magic will not dispel the effects.
And so while the wearer of the boots can perform great feats of action during combat or at other opportune times and key moments, they'll never really want to do so, complaining "Meh, what's the point of it all anyway?" or "I would fly up and save us all guys, but sigh, maybe uhm, soonish, mkay? Bit bored by this whole burning tower at the moment."
Naturally the boots wearer's fellow PCs will grow quickly frustrated with this arrangement. There have been numerous occasions when one angry PC literally tears off the boots from his companion's feet in anger, and dons them in turn, only to immediately suffer from the same effects.
The solution lies in constantly "motivating" the boots' wearer with successful rolls, involving threats, flattery, fiery speeches, or even bribery.
