In silver and gold too?
VERY effective on gold and silver also. I have my sentinel set up like this and I'll note the evolutions.
Tech Armor: (0)
Warp: (6) I chose Detonate, Expose, and Pierce
Throw: (6) I chose Radius, Detonate and Force/Damage
Training: (6) Damage/Capacity, Power, Weight
Fitness: (6) Durability, Shield Recharge, Fitness Expert
Warp: [Recharge - 2.63 sec] [Duration: 10 sec] [Damage - 387.50]
Throw: [Recharge - 1.31 sec] [Force - 1290 N] [Damage - 270]
This build gives the best health/shields and recharge along with the best capacity. With this built you can theoretically carry a Phalanx and a Hornet with Superlight Alloys and remain at 200% cool down just in case you need to shoot. However the main mantra is to never need to fire a shot. It's all about the biotics and the strength behind them.
To elaborate I chose Detonate for both Warp and Throw. The idea is that both features stack and cause a better biotic explosion. All force and damage of the explosion are at 100%. This will immediately drop any of the enemies that have shields and armor down to health or whatever they have as well as the remaining enemies around them. This sets them up for a quick throw or a few rounds to the head to quickly kill them.
The amount of damage and force is staggering easily doing 1000 damage with the explosion and with the amount of time being under four seconds to throw both warp and throw with a radius effect to better trigger the detonation on throw. In a pinch with weak enemies you can spam throw with impunity at under one and a half seconds and with the radius effect you stop more then one enemy.
Against stronger enemies like the hunters, pyros, atlas, brutes or banshees, this takes down three to four bars of armor, obliterates shields and stops them from recovering and again it will kill surrounding enemies nearby the target. The key is high damage and crowd control and this is one of the best builds for it.
