Duel Wielding Only
Against an attack from a bladed melee weapon
that would deal any S or P damage, you may use
your reaction to perform a DEX contest
against the Attack Roll. if you win, you deflect
the attack even if it would otherwise beat your
AC. This deflection creates an opening, granting
you an Opportunity attack with your other
weapon
"The best opening is the one you make for
yourself"
