Bearer can cast spell once per magic phase. Bolt of energy flies 18" in a straight line from the caster. The first model in its path takes 1 S6 hit for D3 wounds, no armour saves allowed. If the first victim is killed, the bolt strikes the next model in its path (like a bolt thrower). It will continue to do this until it fails to kill a target, or reaches the end of its range. Roll a D6 each time the Staff is used: it is exhausted on a 1 or 2.

Note that the Staff of Osiris is carried by the Undead special character Settra, who can use it even though he isn't a wizard.

Line of sight is required for this spell.
