Having finally got my hands on the books our gaming group is coming over to make characters tonight. We have been running KotS pregens for several weeks now. I have made a MS Word character sheet that all really like.
It's one page, 3 columns, 1st is stats, 2nd is inventory, feats and features, and the 3rd column is for powers.
It has about 20% extra room right now, so notes taking will be easy.
I imagine at higher levels a dedicated second page will be used for powers.
And yes, a build can be quick but typing out the powers takes time, as does optimization.
We've penciled in 3 hours (more or less) tonight. I'm looking forward to it. And if they finish up early we might even venture forth into the keep for an encounter with the new party.
Oh, and we have a Cleric, Fighter, Rogue, Warlock, & a Wizard.
