All of performance is less than Priest's. damage, area radius, firing number, range.
It's like
priest = 4 x 4 x 4 x 4 = 256
sexton = 3 x 3 x 3 x 3 = 81
exact stats.
Priest
damage = 200
radius = 2/4/6
firing number = 7
range = 180
Sexton
damage = 160
radius = 1.5/3/4.5
firing number = 5
range = 135
that's why sexton is badly designed. radius both must be 8 and firing number both must be 7 because damage difference is enough for cost difference.
