One Handed Mace PvP ZvZ Build
Overview
This One Handed Mace ZvZ PvP build emphasizes providing utility to your zerg while being hard to kill. Variations of this build are frequently used by shotcallers when leading a zerg, as it offers ample survivability along with valuable defensive skills like 
Force Shield and 
Displacement Immunity.
Equipment
Elder's Cryptcandle could be cheaper while providing roughly the same IP as an 8.0.
Usage
Elder's Mace
Sacred Ground — Very effective when placed in chokepoints due to the silence and slow it provides. Additionally, positioning it beneath enemies using channeled abilities will interrupt them, making it doubly useful.
Snare Charge — A great skill for catching and slowing enemies, as the root can enable you or your allies to follow up with additional CC or damage. 
Air Compressor is an excellent choice when you can catch an enemy zerg without CC resistance, but you need to time it carefully to make it effective.
Deep Leap — Target enemy clumps or occasionally use it as just a stun on priority targets. If you're in a pinch and won't be able to use it to assist your zerg, it can serve as an escape movement skill.
Energetic — Great for sustaining your mana, but once you're familiar with the build and confident you won't need the mana regeneration, you can switch to 
Stunning Strike.
Elder's Judicator Armor
Force Shield — An amazing skill for saving the zerg or tanks that get caught. Demon armor with 
Protection of the Fiends is invaluable if used well, but it can lead to more deaths if an ally isn't also using Protection of the Fiends simultaneously to provide you with the extra resistance. If your zerg has a few Judicator armors, you should opt for using demon armor instead.
Toughness — Straight up increases your defenses. Always good on any tank build.
Protective Instinct — The best option, and it can also be used occasionally to draw aggro from mobs, preventing them from attacking healers or other allies.
Elder's Knight Helmet
Displacement Immunity — You'll usually use this skill when engaging enemies to avoid getting interrupted, but remember you can also use it to support allies. 
Electric Discharge from the Judicator Helm is also a good alternative option but currently not used often with this build.
Toughness — The standard choice for this build. Some people opt for 
Tenacity, but prioritizing your defensive stats is usually more important.
Elder's Cleric Sandals
Blink — A good movement skill to readjust and help with landing good Air Compressor clumps.
Aggression — The standard choice for this build but you can also use 
Efficiency Remember that you can always switch to 
Courier if needed.
Elder's Martlock Cape
Shield of Protection — Used in most tank builds, it can sometimes save you when caught in clumps. It activates automatically, like most capes, making it easy to benefit from.
Rotations
- Tanks typically use skills situationally rather than following a strict rotation. Use Blink to reposition yourself, and Snare Charge to root enemies, allowing your zerg to catch up and group enemies together. As a follow-up or to catch even more enemies, you can also utilize Deep Leap.
- Switch to Air Compressor on your weapon. Use Blink to help you get into a favorable position, and employ Air Compressor when the enemy's CC resistance isn't active. Keep an eye out for when the enemy zerg uses Displacement Immunity, and use your Air Compressor when it's on cooldown.
Consumables
Major Resistance Potion — Use it when you get targeted or get caught in a clump. Otherwise you just use it as a general defensive cooldown but you are tough enough to save it for when you really need it.
Avalonian Pork Omelette — The buff to your defensive stats helps all tank builds and the cooldown reduction is always great to have. You could use a 
Pork Omelette but it is not recommended.
