Do percentage bonuses stack?

Question

I currently have three items that give a percentage bonus to Magicka Regen:

• Archmage's Robes: 100%
• Morokei: 100%
• Ring of Resurgence: 80%

Are these bonuses stacking? Or should I drop the ring and one of the others because they're superfluous? How does bonus stacking work in Skyrim?

Answer 1

Yes the bonus's stack,though during combat they do recharge just a little more slowly then when out of combat but with higher stats like your using you won't notice the slow down really. It's a very good way to have an almost limitless supply of magicka. the stacking works different for magicka regen as opposed to say weapons and such. here are a few links to other such stacking...

hope this helped

Answer 2

AFAIK bonus stacking in Skyrim should be additive. For example if you have x Magicka regeneration rate and both +50%, +70%, you'll end up with x*(120%) so x*(1 + 1.2).

This game should not be like WoW were stacking of % based is usually multiplicative (i.e. 50% + 70% in multiplicative is 1.5*1.7 = 2.55).

Hope this help, Cheers
