It's one person vs the gang of a Strongholder.

Strongholder's gang, as written and with options chosen, is 60 warriors, harm 4 armor 2.
Vs 1 person, with 1e group rules, they'd get +3 harm +3 armor for being 3 group sizes larger than a single dood.
That makes the warriors, effectively 7 harm, 5 armor, (regardless of weapon?) when fighting a single opponent.

Is this the case? (I'm a player in this game, OP is MC). TO my mind, starting with 4 harm is a bit much, but 6 harm 5 armor sounds right for 60v1.

Cheers
