Expertise

Does the Ranger Attribute Expertise work on warrior skills that require Adrenaline.

OK second question then.

Does it just take away how much energy a spell costs or does it take off some cast time, or recharge time to?

i do believe it does not

No, but there are runes that increase your Adrenaline per hit. Expertise works on Attack Skills, Preperations, Traps, Stances, Glyphs, and Shouts.

Adrenal skills don't cost energy to use (Well, not anymore. They used to once, you know) so Expertise has no effect on them. It does work on energy-based attack skills like Power Attack, though.

Also, there are no runes that increase adrenaline gain - there are skills, though, use Frenzy or Battle Rage or others to gain a lot of adrenaline quickly - the Fury Runes I believe Ginko is referring to only increase the amount of time you can store adrenaline when you're out of combat. Normally, if you're not actively fighting - making or taking damage, basically - you'll lose all your adrenaline in 10~15 seconds. Fury runes add a few seconds to that time, I'm not sure just how long it is for each.

Saus is right again.
