## Titan Battle Hits Probability Calculator

Strikes in the board game Titan are resolved by rolling N six-sided
dice, and counting one hit for each die with a value greater than or
equal to the target number T.

N is equal to the attacker's power (half the attacker's
power, rounded down, for a rangestrike), occasionally modified by
terrain. T is 4 + the defender's skill - the attacker's skill,
sometimes modifield for terrain or range, and with a maximum value of
6.
