@ Herzog: I find funny that, with my calculations and your modifications, the highest amount of mana reached barely increases by 40 (To 4085).

I thought that you forgot the damage of W, so I was using the mana cost of the ability as the damage dealt ().

Ok, with both the recommended build and the ability kit now the damage dealt is   on a single strike, the first strike and having you full mana pool; that's for your information ~ bonus damage.

Again, from the first strike and any further the damage will abruptly decrease not only due to mana cost but the percentual cost of the abilities;  now requires to kill with his  ~ minions (Or ~ Neutral Monsters and Champions) to reach the aforementioned bonus damage.
