History of Stacks on Stacks

Stacks on Stacks is a leg armor mod in the Armor Charge system. Picking up an Orb of Power while it is equipped grants one additional stack of Armor Charge on top of the normal stack. Without Charged Up mods, you can hold up to three stacks; with three Charged Up mods the maximum is six.

The original Season of Dawn version was a Charged with Light armor mod that granted an extra stack of Charged with Light for every stack gained, with a -10 Recovery penalty. Whether the current version keeps that penalty is not confirmed.
