Ambri's Wards

Ambri's Wards are available against a number of effects. Each set of wards has the following similar properties:-

Each set consists of 8 half inch cubes with a similar runic symbol etched on each face.
A set of wards can either be carried to give the carrier personal protection or can be used to form a static protective barrier on an area.
To set up a protected area the cubes must be placed in a 2*2*2 stack and the command word word given, the command word speaker can then move each cube to any position they want (provided all the cubes stay within 90' of each other (just over a 50' per side cube). When the command word is given the cubes become invisible to all except the command word giver and those using detect magic, detect invisible, true seeing or similar magics.
Each set of wards has a number of charges. When carried it costs one charge each time it protects the carrier & when set up into a protective field it costs 2 charges each time the area is protected.
Each of the following types of ward has the same base value the only difference is that each different type of ward has a different number of charges.
The Wards cannot be switched off. If the Wards are set up into a protective field and the charges are all used up then the Wards will fall to the floor, loosing there magic & become visible.
The Wards cannot be recharged.
