Где видно из структуры, что одним правилам, даётся приоритет над другими

Each character’s turn normally
gives him one opportunity to act per
second. After everyone takes his turn,
one second has passed.
The one-second time scale breaks
the battle into manageable chunks. A
GM can drop out of combat time
whenever dramatically appropriate,
and resume combat time when
noncombat action gives way to more
fighting.
The turn sequence is the order in
which active characters take their
turns. It is set at the start of the fight
and does not change during combat.
The combatant with the highest Basic
Speed goes first, followed by the nexthighest
Basic Speed, and so on. The
GM decides the order of multiple
NPCs on the same side with the same
Basic Speed. If PCs are involved,
precedence goes to the highest DX. If
there’s still a tie, the GM should roll at
the start of combat to determine who
acts first.

If your attack roll succeeds and
your target fails his defense roll (if
any), you may make a damage roll.
This tells you how much basic damage
you dealt to your target.
