In a recent game, using the Random Happenings rules, a Sigmarite Matriarch appeared on the table in a battle between dwarves and Averlanders (rolled 54 - Last One Standing). The dwarves took her OOA, with some lucky rolls.
The Random Happenings rules allow a model to loot the body, taking her Sigmarite warhamer, steel whip, armour, helmet, blessed water and holy relic. Its a pretty good find!
My question is - can the dwarves use the warhamer and whip? My thinking is that weapon training skill would allow them to use either weapon. Its arguable that the hammer could be used without it but it is described as a different weapon to a regular warhamer and is quite powerful in a warband of good melee fighters.
I have discarded the holy relic, even though it could probably be used in the RAW, since its a Sigmarite relic not a dwarven one.
