Ogryn’s main role in any game is to protect the team, take the bulk of the attention from enemies, and deal with all melee/hordes upfront and personal. Ogryn comes with a vast amount of health and wields some of the biggest weapons available. The typical role of an Ogryn is to keep their team safe from all melee enemies, to take a few hits and quickly replenish your toughness through various skills and weapon perks. This build however, while it is still having a very strong melee potential, it was built with the grenadier gauntlet in mind, and throwing explosions as much as possible.
The Power Maul is a strong weapon to use with hordes, and a good alternate power mode to deal one hit of powerful damage, and really good stagger potential.
Confident Strike provides toughness on chained hits, dealing back to back hits against hordes or single target enemies will increase your survivability. Brutal Momentum makes dealing with hordes much easier, aiming for the head will ignore the enemies mass and allow your weapon to continue it’s swing into further enemies.
Elites and Flak cover the tougher enemies that you’ll want extra for, you can also go for Maniacs instead of Elites to have higher damage increase, but covering less enemies.
The Grenadier Gauntlet is a versatile weapon, more often then not will be used with it’s braced attack to launch grenade projectile into elites of middle of hordes.
Gloryhunter is a big toughness benefit for every Elite kill, able to keep your toughness easily capped so long as you have a steady stream of Elites. Shattering Impact reduces enemy armor on direct impact. This works great for the grenadier gauntlet since the initial impact will weaken the enemy, and the explosion will take advantage of that weakness and deal extra damage.
Carapace and Flak help this build deal with any armoured target. Reducing the armor value of carapace enemies makes them much easier to deal with. Both these modifiers come recommended.
Curios are really flexible, with only a couple perks that really benefit builds. In this case, Health can be substituted for Toughness if required, but health is still recommended. You will want at least 1 Curio to have 1 Wounds on it, wounds increase the amount of health bars you have. This is beneficial, especially on higher difficulties, as it allows some leeway if mistakes happen, or you get overwhelmed.
Stamina Regen is really important and should be the only modifier you go for one each Curio you use. Block Efficiency is great to have to further extend the capabilities of your melee weapon.
