Larian Studios Forums Baldur's Gate III Baldur's Gate III - General The Rogue - Maths are WRONG

I don't quite get the formula they are using.

Why 1d6 * ((level - 1)/2 + 1) ?

The amount of Sneak Attack damage would be (Level/2 rounded UP) * d6

And you ADD that to your weapon damage, not multiply the weapon damage roll with it ...
Sorry, I am too stupid to understand the formula.

Can somebody explain?
