Level 90 Earthshatter Marauder^3.25

Notes

For the majority of early mapping and acts it may be best to use Determination instead of Pride. You can swap later when you have a better body
armour and you are more comfortable.

Since we are not Juggs, we actually have to think about Endurance Charge generation, specifically during mapping. This can be done by anoiting
or pathing to Disciple of the Unyielding, using Endurance Charge on Melee Stun support (its a very competitive support damage wise, only slightly 
worse than other options), or pathing to or anointing Inorexable. If you want to be as safe as possible, use a combination of Inorexable + one of the
others. I still recommend having Enduring Cry slotted at all times for moments of downtime and especially on bosses. It is very important to use 
Warcries have a minimum of 10 Power warcry mastery in order to refresh your charges when there are no enemies nearby. If you find a Kaom's Sign 
ring early on it can be very good until late game. 

If you are having mana issues early on consider removing either Infernal Cry or Battlemage's Cry from Autoexertion.

I personally prefer mapping with Ground Slam of Earthshaking, however if you try it and it doesn't feel good you can continue using Earthshatter until you
get better damage. 

General's Cry is used to pop spikes from Earthshatter since it has a very low cooldown. With full quality on all gems it may not be necessary to use it for 
bossing, you can play around and see how it feels for you. One of the benefits of mapping with Ground Slam of Earthshaking is that you don't need 
General's Cry, so you can put Seismic Cry on Autoexertion. 

If you ever get to the point where you have enough mana reservation to put all your warcries on Autoexertion except 1, you must manually cast Rallying Cry. 
The main damage gain in Rallying Cry is from activating the buff when there are nearby allies from Herald of Purity. You will not gain damage if you 
have this skill on Autoexertion.

When mapping you can swap Physical Mastery's 10% more maximum damage to 50% chance to ignore pdr. Combined with Bastion Breaker this will cap
your chance to ignore pdr. Useful for taking down tanky rares with extra pdr.

Make sure you have a source of Mana Leech. Easiest way is from a Viridian Jewel prefix.

Capping suppress is very difficult in this build and will require a lot of farming before being able to swap. I personally did 4 voidstones and farmed T17s with 
0% suppression but not everyone will be comfortable doing that. Shaper are Uber Elder are particularly deadly due to high penetration, do not underestimate 
these bosses. If you intend on capping suppress you will need to farm Blight and Delirium at some point.

Lab order is personal preference but in my opinion: Double Armour + Action Speed -> +3 Max Endurance -> Warcry CDR -> Defiance.

Leveling skills: Ground Slam -> Sunder until maps

Bandits: Alira. 1 Passive point for 15% ele res is very good value and I usually dont swap from it.
