If A has an agility of 2 and B an agility of 1, no matter when B sends their entry, A's action will always be ahead of B's. If both A and B have an agility of 1, only then will time come into play. If you want your action to be before your opponent's try to get as much agility as you can by choosing the relevant mods. Simple. Also, the person who delivers the killing blow, gets the mod. Unless both have the same agility and both send in at the same time. If thats the case then both players get the mods like both lintara and samon got when they killed me.
