Thunderhorn

One use only
 When a war horn with this rune is sounded its  uncanny voice causes all foes to tremble.
The horn may be sounded once per battle, at the end of the Dwarf player's turn. All enemy units on the field which are not Immune to Psychology must take a Leadership test. If they fall, they are so dismayed that they may not declare a charge in their following turn's Movement phase. Units that move in the compulsory Movement phase are not affected.
