Trophy Racks

Source: Codex: Dark Eldar (1998), p. 15

Many Dark Eldar enter battle bearing trophy racks adorned with the decaying heads of foes they have slain. If a model with a trophy rack slays an enemy in close combat, he may chop off their head and stick it onto the trophy rack! This adds +1 to the model's Ld for the rest of the battle. Unfortunately chopping off more than one head doesn't increase the model's Ld any further, but don't let that stop you doing it anyway!
