GURPS Lands of Legend
In DW some character types are only scantily covered. While it’s possible to wrangle an Assassin into being more like a Thief character, the whole “Roguish” element is a bit missing.
- Stealthy fighters
- Social manipulators
- Mundane healers and poulticemakers
- True Alchemists
All these types are possible in a GURPS Lands of Legend milieu of course. Templates and guidelines can be taken from GURPS Fantasy and elsewhere, like GURPS Historical Folks with its 4e conversion notes here.
