Vanilla Human Sentinel
Unique feature: Good durability combined with the ability to prime and detonate their own biotic explosions versus any target.
Powers:
Tech Armor 6 (Durability, Power Damage, Durability)
Choices here are pretty cut and dry. At rank 6, Power Recharge might be the more attractive option for heavier weapons.
Warp 6 (Detonate, Expose, Pierce)
My standard Warp spec. Detonate at rank 4 is a must while Expose and Pierce soften the target for your weapon damage. And unlike some other power users, weapon damage is an important component of the Human Sentinel’s offense.
Throw 6 (Radius, Detonate, Force & Damage)
Throw isn't going to stagger anything big whether or not you take Force at rank 4; I find it more useful to take Radius in order stagger a group of mooks. Detonate at rank 5 is a must. Power Recharge at rank 6 is useless since Throw already has an incredibly short cooldown.
Passives 0
Most of your power damage will come from Biotic Explosions, which don’t benefit from passive bonuses. Weapon damage passives are a legitimate option, but given the choice between a 65% bump to health and shields versus a 30% bump in weapon damage, I’ll take the health and shields please.
Fitness 6 (Durability, Shield Recharge, Fitness Expert)
Easy choices here. The Human Sentinel is not a melee character, so all skill points go towards durability. Having more health and shields will give a nominal boost to damage output since you'll be able to stay out of cover longer with your finger on the trigger. Spending more time on your feet as opposed to taking a nap also improves overall damage output.
Weapons:
Vindicator w/ Piercing Mod + Extended Barrel
As a Human Sentinel, you have the toughness to exchange fire with enemy troops; you need a real weapon, not a toy gun just to mount a Power Amplifier on. Any of the basic assault rifles that have decent damage and aren't too heavy will do the trick: Avenger, Vindicator, Phaeston, Mattock, Collector, Valkyrie. Since you don't really need any Armor Bonus equipment to do your thing well, it frees up that slot for a Stabilization mod, which is why I went with the Vindicator.
Acolyte (optional) w/ Magazine Upgrade + High-Caliber Barrel
Great for stripping shields, which is the only defense this character is weak against. I prefer not to switch weapons a lot though, so I usually leave my Acolyte at home.
Equipment:
Warp Ammo for the bonus damage to targets affected by Warp
Stabilization Mod to control Vindicator recoil.
Shield Booster because more shields is more better.
Strategy:
Activate Tech Armor
Warp > shoot > Throw (biotic boom) > shoot > repeat
Use Warp to prime targets and soften them up for weapon damage. If the target is still alive after Warp cools down, hit them with Throw to detonate a biotic explosion. Throw is also handy for staggering enemies who get a little too close for comfort or for sending a Husk ragdolling across the map.
Pro Tip: When enemies are clustered together, make sure you let the one you hit with Warp live long enough for you to detonate a biotic explosion. Shoot his buddies, the floor, a teammate, or just hide, whatever, it doesn't matter. The point is to take advantage of power combos whenever possible; let them do the work for you.
