In the Hit Phase, the aggressor initiates a DEX challenge against the opponent, where the aggressor pits his Hit Pool against the defender's Evade Pool.
Hit Pool (HIT): DEX (1-5) + Perks (0-5) + Action (1-5)
Evade Pool (EVA): DEX (1-5) + Perks (0-5) + Encumbrance (0-5)
Both the aggressor and the defender will roll the equivalent number of D10s determined by the score of their respective pools (e.g. 5 Hit Pool = roll 5 d10s), and for every die that rolls an 8 or above is counted as a success. Every roll of 10 (perfect roll) gives the roller an additional roll.
