How I ran Truestone in my (once and future) campaign was that if you had
discovered a piece of blank Truestone and made a POW x3% roll, you could
sacrifice all sorts of things into it. Rune spells and magic points were the
norm. Also possible were attribute points, skill percentiges, battle magic,
all sorts of things. While you wear/carry the truestone you accrued the
attributes for it. A healer once received from an elf lord that she raised
from the dead a truestone with +25% archery, Speedart, Heal body, Heal Wound,
+1 Dex, etc.
Beacuse of this, I have played that you can regain what you sacrifice to a
Truestone. A priest could pray to regain his rune magic. An addidtional POW
sacrifice is not required.
Coming soon, my Praxian vision-quest, rewritten in a slightly better fashion,
I think.
