Some years ago I designed a Berserker class for DCC RPG (you can find a slightly revised version in the 2018 Gongfarmer Almanac).
Unlike my other classes, I finally managed to playtest it a lot in my DCC RPG home campaign, which has been running more or less steadily since 2013. The thing is, in hindsight, I was too much influenced by more mechanic-heavy games. There is just too much stuff going on with the original Berserker. For games like Pathfinder and 13th Age that is neat, but not for DCC RPG.
I'm trying to keep my DCC RPG running light and simple these days, so I changed the Berserker. That also gave me ideas regarding other DCC RPG classes that I've been tinkering with (I'll try to post them soon, especially a much delayed martial artist... the original version was absurdly complex and required the player to distribute points between attack, defense and damage EVERY round... that is a no-fun for me these days in DCC RPG).
With the help of the Berserker player (thank you LeozĂlio!) here is the version we're currently using. Hopefully it is better than the previous one and more fun at the table.
