Energy Recovery

I just crafted some new armor, and 2 of the pieces have Energy Recovery +1 on them. I assumed this was the regen arrows on my enrgy bar, but there was no difference when I equipped the armor. And I missing something or was I wrong on what energy recovery means?

you're correct, however all armors have the +1 regen, so that is not a big buying point on armors. 4 is the max you get, unless you have spells and whatnot on yourself.

I'm a bit confused. So does energy recovery on armor stack? For example, if I have 2 pieces with energy recovery + 1 on each, does that make it +2 now as there are 2 of them?

yes

Your base regen is +2 on your char if he/she was naked
however, leggings and shoes give you +1 each making it a total of 4.

so if 4 is the cap, if I use an enchantment that causes me -1 regen does that mean I can still have 4 regen going?

**If I have +5 regen from armor, 4 is the cap, -1 from enchantment, does the fifth go into effect or is it considered null and void?

Your probably didn't see a difference when equipping the new armor because the old armor also had the same +1.

Energy regen stacks, whether from armor or skills. 4 isn't a cap on energy regen, just the max you can get with the help of armor. There are skills that can temporarily increase energy regen beyond that.

You can only get up to +2 energy regen from the armor sets (depending on class), which makes for 4 arrows on your energy bar. Warriors for example don't get energy regen on their armor, so they're stuck at 2 arrows.

The -1 from maintained enchantments just subtracts 1 arrow of energy regen. If you have 4, one maintained enchantment drops you to 3. Maintaining 4 would drop you to no regen and maintaining 5 would put you with 1 arrow of degeneration on your energy bar and so on.
