Get Death Hand Faster
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.
