The topic of PvP recently came up again over on the Reddit group. I remember seeing an interesting way to handle PvP in “A Storm Eternal”, and I think we could make it work for DW.
When you resort to the sword to enforce your will, roll+STR. *On 10+, hold 3. *On 7–9, hold 2. *On a 6-, hold 1. If your opponent is a fellow player’s character, they roll too and hold accordingly. If an NPC, the GM holds in secret based on the skill of the NPC (1–4, generally). Spend your hold in secret, without knowing how your opponent is spending theirs.
• For each hold you spend to strike hard, inflict +1 Harm.
• For each hold you spend to defend yourself, suffer -1 Harm.
• For each hold you spend to come out on top, you better your chance to win.
Both of you reveal how you’ve spent. Exchange harm simultaneously, and then whoever spent more to come out on top has the other at their mercy. If this is a tie, both get 3 more hold to spend, secret as before, and so on until someone wins or someone is killed.
The question is how to go about switching harm to HP…
