Forbidden technique. Reverse agnostic (archmage)

So i was fooling around and wanted to make EB build for archmage with bananas mana cost. And with some discoveries here and there and some intuition i finally made a mutant build saying to me "kill me".

anyways..

The obvious obstacle was of course that low mana means low mana cost for archmage, and EB potential is wasted. So i found that arcane cloak bypasses energy shield and triggers Indigon, and here you have your desired big mana costs. Also found that putting arcane on left mouse button it gets automated- casts while walking- reduced clunk! Oh, about recovery, you still need mana back right? "dynamo" notable is the answer, also you have to link less (or reduced) duration and second wind to arcane cloak to have 100% uptime (almost) of increased mana cost.

The second problem is that EB is not that good, i mean, what you have is 10% recharge or 10% leech, its garbage for this purpose. Not in every case thou. Here comes "immortal ambition" and vaal pact to the rescue. With this combo you get more than 40% of your life pool recovered to your energy shield per second (can be increased more).

So there you have it, bananas mana cost and bananas energy recovery. I called it reverse agnostic because when you are not on full life you aint recovering energy shield- its same agnostic, it just depends on life leech and not mana regen.

If you want to see very very rough testing scetch there is IronKeeper char. For reference numbers 4.7k life 3k mana, 3.7k es 4.16k es/second recovery, mana cost 1800. Maybe you will do something better, my short experience was.. not very good.

Please tell if you got something better
