Bloodstone:
An amulet with a dark, blood red stone. If the stone is placed next
to the skin and a blood point per level of current Thaumaturgy +1 is
spent, the user gains an additional level of Thaumaturgy until
sunrise. Effects can be cumulative by spending additional blood, point
by point. The stone will have three rituals per level set within it
(storyteller's choice) with a 50% chance of 1-3 paths.  The paths
and rituals may never be changed. Additionally, the stone can be
used as a blood bank. For a tithe of 10% (minimum 1 BP), the user can
store an indefinate amount of blood in the stone.  However It takes 4
turns to get each BP and only 10% of the stone total can be retrieved.
Additional the blood is not actually stored but instead the energy
contained within. The cost per level of Thamaturgy is arithmetic.

To achieve:     costs:
    Thaum 1  ---  1 BP
    Thaum 2  ---  1 BP + 2 BP = 3BP
    Thaum 3  ---  1 BP + 2 BP + 3 BP = 6 BP
    Thaum 4  ---  1 BP + 2 BP + 3 BP + 4 BP = 10 BP
            etc

On top of this blood used in this fashion may not be replaced until the
sunrise. Feeding will not satify the vampire.
