Izanami, Mother of Critical Strikes

My choice of items revolves around attack speed, some pen, and critical strikes

#1 Ninja Tabi - I prefer this over Warrior Tabi because of the attack speed it gives early game

#2.1 Executioner - This is a good item for Izanami even if it just procs on the first hit. Early game, the attack speed and pen is good for clearing and poking.

#2.2 Asi - This is the lifesteal alternative to Executioner. If you want to box more effectively and longer, I think Asi would be the better choice as it has lifesteal and a little pen.

#3 Hastened Fatalis - This item is very useful mid to late game since you will be criting so much that players would usually try to run, so having zero movement penalty is a good way to chase them

#4 Rage - This is where the crits start. Rage can reach full stacks easily when clearing waves. Also, with the attack speed you have at this point, you can crit gods easily.

#5 Poisoned Star - This item slows enemies hit by crits, so it can help you secure kills late game

#6 Deathbringer - This just gives more damage and frequency to your crits

Notes: if Fatalis + Poisoned star feels like a Frostalis, you can always sell Fatalis to get any of the alternatives
