So the thing is you just level Attack Damage (AD) and Attack Speed (SPD) and after SPD is around 3.5 without essence or memory you can then focus to level essences and you should have enough lifesteal to heal from minions and at the Boss Fights you should have enough of Shield and cooldown on shield to protect you, Blink is also here to dodge the One-Shot Attacks from the boss.
