Kinetic Armor
Obsidian Flesh(IS A MUST HAVE FOR THIS)
Ok, come out of Ember Light Camp, and hang a right, past the nasty hydras and you'll see them. Ok, these things have a bad habit of degening your health and removing enchantments, but luckily with Obsidian Flesh, only one of these things is possible. With Earth lvl of 13 the spell should last long enough to cast a few good spells. I normally do meteor first then fire storm then lava font, but dont forget to cast kinetic armor and armor of earth first, before anything. As a matter of fact, cast it before you even aggro them. This may take you a few tries, but after you get the hang of what to cast and when, its not that bad. Also having a good collector staff or wand that improves your recharge of obsidian flesh would be nice, in other words, improves recharge of earth. Also if you get a 2 handing combo going on. With this specific tech, i'd suggest you also get improve fire casting speed. Both of which you know by now hopefully you can get from a collector. Both being 20% chance

.
Well, enjoy the build, and with a little practice, you'll be farming those fleshies with the best of them.
