Is it possible to let another character attempt a skill check?
Say my buddy is interacting with something and there is an investigate option, but his chars intelligence is not up to par, can my char attempt the skill check without him cancelling the interaction and me initiating it again?
Honestly, given the length of early access (and the fact that this isn’t a new complaint) I wonder if it’s actually a choice rather than an oversight. My hope would be that it’s not difficult to implement, and can be modded in now and added to the game later. Fingers crossed it’s not due to a technical limitation
The devs did mention in the weeks before launch that it was something that they wanted to address but that it was very difficult to implement with their current system and how the conversation cutscenes work. They did try different things internally that they never added to Early Access but they weren't happy with any of their solutions and so they opted to focus the efforts on polishing other aspects of the game.
It’s been a while since I played it, but I feel like something like this was in the Divinity: Original Sin games. So you might be right that they simply didn’t want to or couldn’t implement it in a way they liked in BG3.
