[2.0] Art is an Explosion Arrow - Awakening end game crit EA.

how high is the actual crit chance?

Hey Lucifer,
not sure if you're still out there. Anyway, I wanted to give crit EA another go and came up with this CI tree for 2.1:

https://www.pathofexile.com/passive-skill-tree/AAAAAwYARXyXl_v1tDjlGYw2B2OJ08u9cFLmgSoLFr9d8g-rDkgrCm1sJIsRluOEES_ndLVI7LDDOn_GBx4N0etj2xqMC5u1KjiTJ6KjlS5jQxB7uXyExb6KbAvviFF0D8Tw1b46oS_K0yL0-TcagTt8j_pJUbQMbRnXz6aZuMrsGOq6snBGcRFQ2VuX9EmxLL8NfCpTgwk1uRslUlMV12-eYEOnKx1PS66XlT1fhq6cpG496QJMs1ZjhxO-gN-KIG7QHwQHdwdQMO_r6-RfKnRVrJj31_FshEg22FxrSRvDbSqN7FU=

It's got a huge amount of ES and damage, as well as a big mana pool to hopefully sustain EA on mana.
For gear I'd use a +1 arrow Death's Harp, Soul Strike, Infernal Mantle for decent ES and great damage, maybe maligaro's - rest high ES rares. Should be possible to hit 10K ES with near-instant recharge, allowing this to hopefully survive in HC.

Obviously Infernal Mantle makes it hard to manage mana, I'd say either Discipline + Clarity, or if possible Disc + PoF with a higher level enlighten.

Any thoughts?
