Heya!
Many still seem to be asking, I´m still in possession of the
strange stone? I can happly say that I still am. Since there still
seems to be soo many questions revoling around the stone. I´m passing
on more of what I have learned. There was some controversy over the
nature of the stone that was brought about buy the first three breaking
in the hands of the mystics that had acquired them. Some thought
perhaps it wasn´t a mystic tool, others thought the stone needed some
sort of tuning or charging. Well, after now having the stone for over
3 months, the controversy seems to be clearing. Here is what I know.

The Strange Stone is identical in effect as the teleport ring was
before the rip-wars. The ring was a mystic tool.

Full Mystics have a trainer that deals with Teleportation.

The stone prior to the current wave remained "Dark" when equipped.
There appears to have been some unkown reason in which the stone was
not correctly assessing the mystics training in it´s use. I think
this is why they broke soo quickly for the mystic who had on in the
past.

Since Right after the last chaos storm the Stone now glows in a
variety of different levels when equipped. The level or the "Glow" is
still under investigation, but appears related to the level of training
I have in the teleport trainer. The glow can range anywhere
from "Glows Brightly" to "Flickers" or it can even remain "Dark" on
occasion. Most of my equips cause the stone to "glow"
or "glow Brightly" which seems to be a good sign.

Because of these since the chaos storm I don´t believe the stone
requires any charging or tuning. I have tried numerous areas including
the Bartok Altar in the Orga Village. They don´t seem related.

I have now successfully used the stone 3 times now, 2 times to "mark a
location" and one to actually teleport to that mark.

I hope this clears up some of the questions that still linger.
