As part of a change to DML's Energy system, we have removed all the "energy gems" (i.e., Portal Gems and Arena Gems) and have converted them to the new system. Instead of collecting "energy gem" consumables that can be used to top up your Energy for either the Portal or the Arena, you'll now collect Portal or Arena Energy that will automatically be added to your current Energy. If you are at maximum Energy, it will be added to your total as an Overcharge, to be used the next time you expend Energy. As part of this change, we've converted all "energy gems" into Energy; Portal Gems have been converted to Portal Energy and have been added to your total available amount of Energy. The same is true for Arena Gems.
