The One-Handed perk tree contains Armsman:
- Armsman (One-Handed weapons do 20/40/60/80/100% more damage)
And the Stealth perk tree contains two perks which can modify one-handed damage:
- Backstab (Sneak attacks with one-handed weapons now do 6x damage)
- Assassin's Blade (Sneak attacks with daggers now do a total of 15x normal damage)
Are the effects of Armsman and Backstab/Assassin's Blade additive or multiplicative?
let's say I have the rank 5 Armsman perk and a dagger which inflicts X base damage. My dagger should now inflict 2X damage:
(X + X*100%).
Now I acquire the Backstab perk. When backstabbing, will my dagger inflict:
- 7X damage (
6X + X*100%; perks stack additively)
- 12X damage (
(X + X*100%)*6; perks stack multiplicatively)
