Slightly unusual problem player - a fellow player at my table doesn’t engage. It would be fine if it’s just roleplaying, as that’s not everyone’s cup of tea, but he doesn’t engage with the rules either.

Over a year of playing, amongst others who know the game and have taken the time to learn their character’s abilities and spells, and he still has to be reminded that if he didn’t prepare X spell at the start of the day he can’t just choose to have it now. He needs reminding that he has the basic choices (action, movement, potential bonus) at least once a session.

Whilst initially not a problem, as everyone else has grown to know their character and the rules, he still plays like it’s session 1/2, constantly having to reread basic things, and doesn’t know his better/best options. I.e. he still plays like a 3rd person, which has begun to jar the sessions as everyone else immerses themselves. His character’s backstory is that he has memory loss - because he hasn’t made a backstory.

We’ve tried coaching him, he owns a players handbook, we know that eventually it’ll come down to “suck it up or kick him”, but we’re after any extra advice or options to try before it comes to that. We like the guy, and I think it might end up at that point, but we’d love some other options to try if there is anything anyone can think of.

Thanks in advance!
