It was only a matter of time, right? While technical tricks like stacking a thousand explosive barrels or leveraging fall damage for Owlbear elbow drops are impressive in their own way, I’ve yet to see anything truly representing Dungeons & Dragons’ frightening powergaming underbelly from Baldur’s Gate 3’s community. That is, until now.
I skimmed that article, but from what I remember, in 5th Edition you’re only limited to only one bonus action per turn. Meaning that stacking that many bonus actions is probably a bug rather than a feature.
