Heretic of The Seventh Circle
This may sound strange, but maybe he needs some tactical options. Maybe dig into how to support more tactical play without bogging the game down, and he will engage more. I've seen with with at least two players, who wanted to play analytical, tactical characters. 4e was a boon for them, because they could dig into their character's tactical options without having to stop and ask questions OOC. they literally became highly engaged roleplayers over the course of the middle heroic teir, because the game supported the kind of character they wanted to play.He is a Water Genasi Wizard, no alignment or background. He has a bit of backstory, based on him living in the city of Genasi, but it has not come into play much. By the players own description his Character is analytical, and prefers planning over acting in combat. The whole "spend 6 hours sharpening my axe" thing. The issue with this is that both of the others' characters are extremely forward and very much people of action, so while they are in a super intense fight, he will stop everything at his turn to ask tactical questions.
It may be a simple lack of experience, but I feel like he just hasn't grasped how to get in that frame of mind, while the other two hit their stride easily. I can't speak for myself, as I am lackluster at best when role-playing the NPCs, but I don't want him to feel left out of the game.
As far as tropes, the most I can say is maybe. He has chosen all of his characters, and they tend to be either odd or blank. Maybe he is just swinging for the fences, and falling short by trying too hard, but he has yet to be interested in trying any sort of basic cliche or classic trope.
5e can do that as well, but it's less strongly supported.
The point is, perhaps what is needed is to find options that let the character tactically analyze without spending turn time asking OOC tactical questions.
