Okay, here's a magic item that I think isn't too powerful. It's very
useful in the context of the adventure I'm writing, so I want to give
away a couple of them. Is there some use of this item that would make it
super-powerful -- in other words, am I missing something obvious?
Here's the item:
A
rock of stability, unsurprisingly, appears to be a
normal rock. The rock’s possessor cannot be affected by turbulence,
although a steady force of air or water, such as a gust of wind, will
still exert one half of its normal effect in that direction. Taking
river rapids as an example: the character will be moved down the river
at half the normal speed and with half the normal force that the river’s
flow exerts. However, the character will not be thrown from side to
side in the rapids at all. If the river rapids are moving at a rate of
7mph, the character will be forced along at a rate of only 3.5mph, and
will thus likely be able to avoid rocks much more easily than a
character subjected to the full 7mph force of the river. Only the
movement of gases and liquids is affected by the rock; a moving wall of
stone or a falling anvil would push or strike the character as per
normal.
(This isn't intended as a test of your ingenuity as a player, although feel free to show it off if you want. It's really about whether there's a fairly obvious use of it that I haven't noticed).
