Since fragility is an AoE hex now, there's definite synergy between it and crystal/tenai's wave. One of the gripes I've always had with farming as earth ele was the fact silver armor was really the only option for damage.
So, I've been thinking about it and I came up with a possible build.
Crystal Wave
Fragility
Ward of Weakness
Erruption
armor of earth
stoneflesh aura
?
?
basically you'd hex everyone with fragility then cast ward of weakeness and Erruption, causing 200-100 earth damage + 36 dmg from fragility (at rank 12), then casting crystal wave will do +100 armor ignoring damage +36 from fragility, and if you cast it while erruption is still going off, the blindness and weakness will be re-applied, and do another +36 damage.
So a total of 200-100 + 208 armor ignore damage, for a total of roughly 308-408 damage over 5 seconds. And thats just with those six skills.
You can bring obsidian flesh + glyph of swiftness as your last two slots if needed, of if casters aren't a problem then you could bring Tenai's wave for another +172 amour ignoring damage, and maybe an e-mangement skill.
Unfortunately I don't have EoTn and I can't test how effective it is myself, but maybe someone wants to give it a shot on mountain trolls or something? (as a proof of concept).
