Not sure if anyone else has noticed but this formula for the calculation of sneak attack damage is wrong unless we aren't following typical 5th edition sneak attack rules.
Are we getting 1d6 SA damage every level in BG3 or or every like is core DND 5 ruleset?

This formula is only accurate to core DND rules for level 1.

For example:
(Assuming decimals round down as I expect.)

Level 2 should only be 1d6 still.

However:
1d6 * ((2(Level-1)/2+1)
becomes
1d6 * ((2(2)-1)/2+1)
1d6 * ((4-1)/2+1)
1d6 * (3/2 + 1)
1d6 * (1 + 1)
1d6 * 2 or 2d6


Level 9 should have 5d6.

However:
9th level rogue would have
1d6 * (2(9) -1)/2 + 1) =
1d6 * (18 - 1)/2 + 1 =
1d6 * 17/2 + 1 =
1d6 * 8 +1 =
1d6 * 9 or 9d6

I believe it should be:
1d6 * ((level-1)/2 +1)
