Quartz Knot
Aha, a Knot based on Nether Quartz crystals! It seems more than just gems can be turned into mana containers.
This one however, has a rather abysmal capacity, on par with its Amethyst sibling.Its natural recharge rate is also pitifully at the levels of an Emerald Knot of its same capacity. Not terrible, but definitely not great.
It seems to have one redeeming quality though.Augmenting a Ploy of Receipt with a slot as a second argument, it is possible to listenfor messages from an item.
Most items do not react at all, but trying the same on this knot, it responds!
When a Quartz Knot is queried in this way, it replies with an ever-incrementing number,starting at zero at its initial creation, and counting up by about twenty every second.
A message can also be sent into the Knot using a similar method to resynchronize it,and offset its counter by a given number.
If one listens closely, the faint ticking of a clock can be heard coming from within the Quartz Knot...
Yet, the Knot contains no moving parts...
What a strange object...
