Extending this report, there can be also a "graze" chance. Preferably for ranged
weapons only, based on melee hit chance.
(That is, when a melee attack would miss, a ranged attack graze)

Or on hindsight, maybe it would be better for the game to just grant 100% acc
for everything and everyone, and use the miss as graze (deals half damage)

Because our average weapon power, I do advise that critical increase damage only
in 20%. For initial feature implementation (as a simplification) the dex state
can be used, but the formula will need to be different. In long-term it may be
not-interesting to make it dependent on dex (balance reasons). Maybe physical or
strength are more suitable, because "with a strong body you can easily overpower
your opponents."
