So about Entangle -- it seems to last for only one turn, but the counter counts down at the start of the entangled character's next turn, meaning they're immediately untangled and the spell effectively does nothing.
It's a wasted spell slot to cast this on an area enemies are already inside. To be effective, you need to cast it on an area the enemy will pass through, as they then lose their turn of they fail the check.
Just for comparison, these are the differences from Entangle in the book:
1. 5e raw lasts up to 1 minute, is concentration. Actually Ijust realised I don't remember how long the effect lasts in-game because I deliberately set it on fire to burninate the intellect devourer held within it, I have to check. edit: Is concentrations, seems to be a minute-ish
2. 5e raw makes the effect area troubly walky, but only ensnares characters inside it when it is cast -- BG3 version also ensnares characters who enter into it. edit-addenda: BG3 version also can reensnare somebody who walks for too long inside the area.
3. 5e entanglement last until the character passes a strength check (costs an action to try) while in BG3 it lasts until the start of the entangled character's next turn.
So basically, presuming the duration issue is not intended, the BG3 version basically trades possible duration of the restraint for the possibility to entangle more creatures.
I think the duration issue may be because it might be coded as to just create a "thorny wine" (you know like we already had in-game prior to this patch, I can't remember the exact name of it) surface effect, and the existing thorny wine effect presumes that a character runs inside it it on their own turn rather than the effect being called on them on another character's turn.
