Surprised status - working as intended?

[WereElf]

When you are stealthed and attack enemies, they start the combat surprised and miss their 1-st turn. Is this a homebrewed rule, or is it from the DnD rules? Are there exceptions to the rule? I think I can recall there being a feat, or perhaps a racial feature, protecting you from it?

But my point is: when you attack frienemies from stealth, instead of entering combat right away, they tell you something in the lines of "Now you'll pay!" and THEN they enter combat, but they are not surprised. Is this working as intended, or it has not been properly implemented?

We saw this happen during the last PfH too - during the goblin fight. However, it was unusual encounter, as 2 party members had already started the combat (and lost), and the 3-rd one RESTARTED it, so I'm not sure if it would've worked, had it been started like this right away. They do seem to have 'fixed' another aspect of entering combat from stealth - the character was missing their action point, which they've used up for their attack.

That's how surprise works in DnD, yes. It's up to the person running the game to determine if someone is surprised or not though.

Generally, if you still haven't been detected after the attack, you get the surprise round.

Hiding seems to be a full action again, yes.

In this case the naration after attacking a friendly seems to kinda break the surprised round.

In Solasta it's the same, attack enemy while stealthed and you get a surprise round and vice versa.

BG3s mechanics are "worse" because - just tried it out some days ago - you can group stealth, one of your guys attack the enemy, the combat starts just for him. The other party members stay outside of combat and can attack too and get involved OR - and that's the worse part - can move freely around as long as they don't cross the enemy view lines and i.e. placing exploding barrels or do other stuff or get in a better position for AOE spells, whatever.

In an earlier version you could also shoot enemies with a bow multiple times in row from far away and kill them out of combat- don't know if that's still possible.
