Double tap
Tier: 2
Prerequisites: Two Weapon Wielder
Aptitudes: Finesse, Offence
The Acolyte is practiced in making dual attacks, and can almost
subconsciously tell when his hits strike to best effect. When making
a second attack action in the same turn, he gains a +20 bonus to
the attack test if his first attack scored one or more successful hits.
This would make more sense to me if you only get the +20 if the shot is against the same target. What do people think, would that dilute the talent to much making it mainly useful against bosses and elite type mobs (assuming mooks are 1 shotted)?
