I’ve run across some really great accessories and play aids for 4e D&D during my internet journeys and I figured, “I’ve got a blog, why not share them with my readers?” Revolutionary thinking, I know. I’ve already used some of these in games, and I especially enjoyed the crib sheet, which really helps new players (all of us!) figure out what they can do on their turn.
Power Cards - Complete Set: These things are swwww-eet. They’re pretty, and functional, and cover every PC power in the 4e PHB! Megaprops to Ander00 over at EN World for these. EN World post
Kiznit’s 4e Character Sheet: It’s pretty good now, but I’d keep checking back as he’s going to add a third page with blank power cards. Of course, you won’t need those if you keep reading. Direct Link (several pdf version links in the post)
And that's just the first two. There's more gold in them thar hills, including other versions of character sheets, initiative and effects trackers, and other helpful aids.
These are the sorts of things I would think WotC's D&D page should be highlighting. Still, it's good to see the community really charging ahead with these sorts of tools.
