Whilst feeding my son his breakfast milk, I was thinking about wu jen. Not that I'm obsessed or anything. So, the idea behind them is of a dynamic, slightly tougher, wizard. They have better weapons and more hp than a magic-user, but still cast spells. Who does that sound like? Elves!
I'm going to work from what we have in 1e and format it as per LL and AEC; then I'll see how it stacks up against the elf.
