Inspired by this post by Wizard Lizard over at Underworld Adventures.
I like Zweihander from an aesthetic standpoint, I really do, but unfortunately I have OSR/FKR brainrot and so I can't run or play a system that complicated. However, what I could do is use the character creation method from that game and tweak it for use with a less complicated system.
The stats in Zweihander are Combat, Brawn, Agility, Perception, Intelligence, Willpower, and Fellowship. Normally you roll for these stats by rolling 3d10 and adding 25 to the result for each, but that's a little too complicated for my tastes, so instead how about you just roll 3d6 for each. Write down any stats that are noteworthy, ignore average stats.
Next roll a d6 to determine your race/species. A 1-4 indicates you are human, 5-6 indicates you are demihuman, the exact type of which is determined by the table below.
