Larian Studios Forums Baldur's Gate III Baldur's Gate III - Technical & Gameplay Problems Sneak attack bug with booming blade!

If I cast booming blade while being invisible the sneak attack damage doesn't work. The attack is done as if I had no advantage. I tried setting sneak attack to reaction as well and I get no reaction window pop up to apply sneak attack damage.
Tested with Dark urge cape on a Thief Rogue as a High Elf(booming blade cantrip).

If you fix that bug, please consider looking into opportunity attacking while invisible as well. A reaction window should pop up if an enemy decides to move away from you while you are invisible. But right now, if you are invisible, you cant opportunity attack.

Question;

Does Booming Blade trigger sneak attack if other criteria for it to occur are met (Another ally next to the target or Swashbuckler) and thus it is only specifically when using invisibility rather than the cantrip as a whole?

Also, does Arcane Trickster make it function?

I ask because I genuinely don't know, so I'm curious as to the extent of this issue to narrow down the exact nature of it; the first question would be in regards to whether this is a bug with invisibility, the second would be in regards to its nature as a cantrip (And AT enables cantrips/spells to sneak attack)

Booming blade casted while invisible ignores sneak attack dice. No other criteria helps. And as far as I know, arcane trickster being able to sneak attack from spells was fixed on patch 4 unless they have reintroduced the bug in a recent patch, so I don't think it makes a difference.

I just played around with some respecs.

The bug seems to be with invisibility.

Both normal attacks and Booming Blade works without it, both regular Rogue using Hide for advantage and also Swashy just attacking something.

Invisibility is making it not work for anything. Normal attacks or Booming Blade. Neither work when invisibility is used (Even with Hide AND Swashy meaning there are 3 criteria to enable Sneaks and invisibility stops them all)

The behavior is very strange. I've tried using handcrossbows to attack from invisiblity and it correctly applies the sneak attack. So, the bug is with invisibility and melee attacks that applies sneak attack damage dice passively.
