4th job Single Target DPS

kso. Assuming everything still works the same:
Combo Multiplier, 10 orbs
= Combo Attack % + 20% + (orbs - 5) * 4%
= Combo Attack % + 20% + (10 - 5) * 4%
= Combo Attack % + 40%
Note: Combo Attack % can be found in Skill/112/1120003/level/30/damage and Skill/1111/11110005/level/20/damage for Hero AC and Soul AC, respectively.

Soul AC Multiplier, 10 orbs
= 140% + 40%
= 180%
= 1.8

~integrity check~
Hero AC Multiplier, 10 orbs
= 150% + 40%
= 190%
= 1.9
