my hit have 700k-1.5milions! But with my hit pool i should take all time full hp for 1 hit, but smth if base hit is lower from damage distance i have like 2000hp of leeach, but i think i am not good at mathematic, and 10% from 700k its 70000 for 1 hit!!!!!!!!! i will give video with demonstration, there u can see that some hits didint give full to me from leech.

That's not how it works. When you read the leech tooltip you will see that monsters have leech resistance that lowers the amount you leech.

Ok u think, hexblast lvl 38 have 2600+ mana or life cost, is okey ?? when u give more than 2 hit in second (5200+ mana or life cost), ever all mods to less manacost and inspiration cant give use this skill all time, is it will fixed or smth?
