How to increase R/E energy?

I'm running a level 13 R/E, and my energy seem sstuck at 25. Is there any way to increase my base value, or is equipment my only hope of adding a few points? Equipment is the only hope as a Ranger. But expertise is a fantastic Primary attribute. You can use a druids set, and a +5 energy bow to actually increase your energy pool....but what are you trying to do with it?

expertise only reduces the costs of ranger skills only tho which is mildy dissapointin Expertise is not profession based. Spells, hexes and enchantments are not concerned. The rest does (various attacks and skills only listed as "skills"... like Blackout for example).

Equipment and glyphs. Use lesser energy for those big casts, and avoid exhaustion if possible. Get a +15 staff or +5 wand with a 12 or higher off hand. My question is, what the hell are you trying to cast that you need so much energy for? Rangers are not meant to be nukers and such. He's level 13. Probably just struggling with 10e skills from his Ranger profession, because of little to no Expertise.

ChaoticCoyote: go with full Druid's Armor (32 mana, a must) and 9, 12 or 13 in Expertise. You will be able to once you're level 20 with both quests done for skill points. Just know that every level in Expertise makes your skills 4% less energy-consuming. You can find information about it in Guildwiki for example.

Have fun.

RUNES! I use runes and now my energy is pretty high. Exactly what runes do you use to alter your energy? Isn't the energy storage rune the only one that effects total energy? That is an elementalist rune.
