CHAOS LORD model only (excluding TERMINATOR and JUMP PACK models). In the Declare Battle Formations step, you can set the bearer up in Reserves instead of setting it up on the battlefield. If you do, in the Reinforcements step of one of your Movement phases, you can select one model in a friendly LEGIONARIES or CHOSEN unit that has two or more models remaining and is on the battlefield (excluding Attached units). The selected model is destroyed (ignoring any rules that are triggered when a model is destroyed) and the bearer is set up as close as possible to where that model was destroyed and only within Engagement Range of any enemy units if the destroyed model was within Engagement Range of those units. The bearer now attaches to that unit as its Leader.
