This Party is Off the Hook!
A Miniguide To Party Optimization
4E is a team game. You can create characters in a vacuum if you want, but the most effective characters are those in parties are here the characters are created to work in a group and to complement each other.
One of the most common questions I see on these boards is what character should I add to my party. I love those threads and this guide is a place to discuss how to improve parties as a whole and if you have a question about what character you should add to your party, this is the place to ask. Please contribute any strategy suggestions in the comments an politely argue away about what you think is more important to a party.
This guide will discuss the basics: The importance of Roles, how to fill in gaps, skills, range vs. melee, character synergies, party size, and any thing else people think is important enough to include.
