DOT does ball lighting or lighting in general count as damage over time

I have a question when I put on the Xfal’s Corroded Signet ring its unique power affect is … Lucky hit: Your Damage overtime effects have app to a 50 represent chance to erupt dealing 35,852 damage of the same type… So when I put that ring on I can see the explosion of lightning happening every so often so either it’s a bug or it’s obviously counting my lightning as damage over time right?? And if so I wonder if I should be more mindful of items that add to damage over time damage little confused on this one

ball lightning is no dot its normal direct damage

its not its just 400k plus damage per ball every second

I don’t think any lightning damage is considered over time tbh, I have never seen any lighting explosion either, teleport causes smt like an explosion of electricity maybe that’s what you see? or if you use the cameo, when you collect crackling energy it explodes right?
