The ridiculousness of the items break immersion.
Furthermore, these lightning charge items are everywhere throughout the realm with no background or lore tying them into anything. DOS 1&2 had "sets" of items, but at least they were explained and poorly tied to a storyline or a character to give credibility to their existence.
These were just haphazardly made and thrown around the world and they're not BALANCED.
It feels awful.
the lighting charge items do have a background. guess you didn't pay attention. they all come from the owner of the arcane tower in the Underdark and her partner.
