Because Death Hand becomes less accurate with use, it is best replace it quickly during war. To do so you must choose to be the House of Harkonnen (red), constructing a stronghold and palace before waging war with the enemy (using Death Hand of course). Next, have your army destroy your own palace! Under 'friendly fire', a new Death Hand becomes available instantly, so you won't have to wait until your palace is fully constructed to use it. Note: Pillaging your own palace is costly, so you'll want to have lots of credits or use a code.
