With a point in Leadership and a high enough level in this skill, the player can simply activate Expendable Assets and keep it active while traveling. The Digi-Jacks left behind will despawn, count as a "kill", and extend the duration of the active skill, allowing Expendable Assets to be active for a significantly long time, even out of combat. If no enemies are encountered, the skill can be deactivated, with the cooldown refunded often making it a short wait before Expendable Assets can be used again.
Using the above mentioned strategy, the player can summon Digi-Jacks for minor battles, gain back the duration lost from using the skill, and deactivate Expendable Assets. This will refund significant amount of cooldown, allowing the skill to be used again almost immediately.
