Larian Studios Forums Baldur's Gate III Baldur's Gate III - General What's an exploit? (What do you consider cheese in BG3?)

Nah, extra attack shouldn't be stacking with itself, no matter the source. A single-classed fighter 11 should be the only class getting base 3 attacks, not a level 10 multi-class. That's just unimplemented coding.

The 5E rule book, page 164, is explicit on this.
