He's definately a powergamer. None of his tactics are annoying or lame. Most of them are pretty slick. I am actually very grateful to have him in the group because when the players are in a tight spot, he always comes up with a way to help the group out with a spell. I've been on the opposite end where a cleric player wouldn't even know he could restore someones lost ability points :\ so this is nice.
I actually suggested this to him last weekend. So far I'm doing the right thing
Actually, he's been annoying about this. He already powergamed his wifes PC, but she doesn't know enough about the game to really take advantage of things. She's really effective at archery, but that's about it. I can still thwart her PC without bending over backwards to do so.
Our sorcereress player on the other hand is getting annoyed by his constant "advice". She's a casual gamer and prefers roleplaying. She tries to perform well in combats, but his constant suggestions are getting on her nerves. What's worse is they are all levelling this week and he made several comments last session about the spell she
needs to learn. He said it so many times during the game that it's as if he's trying to build her character for her in order to powergame the entire group. The last time she levelled I appreciated his help, but now that I see the impact of powergaming, I'm not thrilled about letting him give her advice. I told her we'll level her up before the game so he won't bother her with spell selection suggestions.
Thanks for the advice, it was great!
