1. Plague of Rust

Plague of Rust is a hex with a range of 24". The
target's armour save is lowered by one point
for the rest of the game (e.g. a model with light
armour and shield will only have a 6+ save).
Plague of Rust can be repeatedly cast on the
same target, reducing its armour save by a
further -1 each time. The Wizard can choose
to extend the range of this spell to 48". If he
does so, the casting value is increased to 10+.
