Fix Greater Invisibility

Problems:
1. It is not supposed to break/dispelled on a failed stealth check.
2. Balance wise it is basically the same as regular invisibility because it breaks anytime you do anything. The spell itself typically came with a bonus to stealth checks of like +10 or +20 in other dnd games to allow it to actually function.

Here is a link to a page of 5E spell Greater Invisibility for you. It also has a video of developers discussing the spell answering some common/complicated questions.

Key takeaway = This spell should remain on characters even after a failed stealth check because its still giving the character advantage on their attacks and its also giving enemies a disadvantage on their attacks against you.

Also the stealth check simply means the enemy has "infered" your characters position. It does NOT MEAN they have broken your invisibility.
Example: The enemy has heard you take a step so they infered your position but you are still visibly unseen. Which is where it makes sense that its harder to hit you and easier for you to hit them.tion but you are still visibly unseen.

Right so the AI would be in it's right to attack the correct location but at disadvantage. And the character with Greater Invisibility should retain the spell.

This also means each enemy would need to do passive perception checks against stealth at the top of their turn, and an action for an active perception check if none of the passives are good enough. To clean this up, for a tactical CRPG, I'd just make passives not work on greater invisibility, requiring enemies to do an action to actively search or cast a spell or throw an AoE substance.

Then if line of sight was broken with all enemies, and the character is still invisible, there would need to be a new search action, spell event, or AoE attack.

Be aware that BG3 has modified rules for video game purposes. Quoting 5e official rules doesn't mean much.

There are pages scattered around the Internet of what differences there are between BG3 and 5e. It's only based on 5e.

Yeah. For the most part the changes for video game are pretty good.

There's some haste cheese, but I love throwing barrels so LETS GO!

I do agree with OP that the current implementation of Greater Invisibility isn't doing the spell justice in combat, which is where it needs to differentiate itself from level 2 Invisibility.
