chaos version has none of it.
so I suggest adding +2 meters target area to DB to, say, Bloodsword Repeater which is also the only weapon to fully convert DB to chaos.
I would like to remove increased radius from everywhere, but make a specialized DB item with Covenant Crown by adding +all damage, -cd and +AoE to Doom Bolt
Maybe remove % vitality damage and add +/- 200% all damage to the scepter and reduce the % Aether damage.
But i see that the lightning DB has problems with it, because you need the MI item.
I have an Acid DB Sentinel that works fine with all the items, but a little bit more dmg would be good, because i dont have acid damage on each item.
