I was one of those people who wanted edwin to be a playable character in this Game. But we all know, Lore says, edwin is dead (wouldn't be the first time he tricks death and decieves people to believe him dead, but lets roll with it)

So here goes another suggestion how to add a little something to the Game, that will connect us with the old BG1/2 games. Edwin was wearing a Necklace back in the day, that you could not remove from him (he won't even let you touch it), so I guess this Necklace meant a lot to him. If I am not mistaken the Necklace never gets mentioned any further (unlike Minsc companion Boo), so there is room to bring this trinket back in.

So my suggestion is to bring in a Special Necklace Item, that gives the wearing Wizard 1 bonus Spellslot of each spell-level 1-5 (or something like this. I haven't thought about the real stats there). But there is something special about this amulet. Like the talking sword in Baldurs Gate 2 (i think it was Lilarcor) the Amulet of Edwin could have a piece of his Soul bond to it, so it responds to anything you do by commenting it with edwins typical snazzy lines, like:

"Are we trying to waste time with this baffoons or are you just so easily entertained?" when taking too long talking to someone
"Back in my living days, I would have solved this problem easily" when failing a skill check
"I am surrounded by idiots" just because it is a typical thing he would say

It doesn't need a full developed character story and would be a nice thing to give to the old BG players without having to bend lore or your story. Plus it would be hilarious if Gale would be permanently pissed by Edwins "advices", because they both would disagree so often but both are jerks. This Item would totally fit into this whole game, so I thought of suggesting it.

P.S.: Thanks for making BG3 such an awesome game. I really enjoy playing the EE and try to support you as much as possible. Thank you Larian.
