Advice for my Vitality Conjurer

I am currently level 27 [hc] playing conjurer.

I was wondering if someone had any better ideas of how i should have my points spent?

Also, what exactly am I looking for on gear. I have a wand or dagger with 48% vitality dmg and x% decay with +2 to Devouring swarm. I am using Explorers boots and chest. My offhand is a 38% vitality dmg , regen cooldown offhand. Then random other items.

I was wondering if I was doing it correctly or if there was a better way to make leveling easier?

I recommend putting more points into mastery. I usually do two points in mastery per level and one in an actual skill. I do this until I get at least one mastery maxed out. I did a similar build that is up to level 70.

More mastery points will make you more durable and allow you to wield better equipment.
