[2.2] PHC - The 8.4k (Life) Iron CoC Spin (w/Bladefall + EK) - Juggernaut

Since this mace always crits, cast on crit is a natural choice to use with this item. Unfortunately, there are two difficulties with this item.

One, it is slow. To overcome this, we need a skill that scales attack speed a lot. Cyclone is a great choice due to it's 50% more attack speed as part of this skill.

Two, since it is a two-handed item, we need a way to get defenses. Fortunately, the Juggernaut has "Unbreakable", which doubles the armor from our chest, as well as making us stun immune. The problem is then that a high armor chest will have a higher strenth requirement than the mace, making it difficult to get the colors we need (at least two green sockets for Cyclone and Cast on Crit, and then we need colored sockets for the spells we want to use). So the best option is to link and color the mace. Doing this in Parandus HC has been a straight up nightmare, so you'll need currency to do it.

After overcoming these, the options are elemental or physical spells. I've opted for physical, as you don't have to worry about penetration gems and can just focus on scaling damage through Iron Will. There are other variants possible (e.g., elemental equilibruim CoC), but I've chosen to focus on physical spells.

The two important attributes you want on your jewels is % life and attack speed with maces. Attack speed is needed to help overcome the slow base attack speed on Trypanon, and mace attack speed can roll up to 8%.
