Weapons:
I recommend the M-13 Raptor, a high level Viper, or another burst fire/Semi-Auto Sniper Rifle.

Strategy:
Energy drain is how you stay alive despite 0 ranks in fitness, the 40% boost to resistance in damage means you can survive briefly if someone fires on you, the damage isnt super, but its a guarenteed 100% shields back if your in cover, and in 95% of the time you want to be.

Decoy, is built to handle anything thrown at it from any difficulty, your looking at the best possible health for it, and longest time for its cost, it will be nearly thirty seconds of time, with only a 2.5-2.75 second cooldown. That adds up time for powers like energy drain and incinerate. It is a hard power to master well, but used well, this can net you a complete and utter shutdown of one avenue of attack. Letting your team focus where it matters as you hold the fort against banshee’s, primes, and phantoms and atlas’s. Shock is there to stop swarmers, and make sure that you catch geth hunters that you might have missed, or ensure a husk isn’t trying to grab you, which can easily lead to death when you couple them with swarmers.

Incinerate: This is both your anti-cerebus power, and your anti-reaper bread and butter. It helps burn down the geth pyro’s, since this power has a travel time, always try to shoot at your target with your weapon as it travel, so often you can land both a tech burst, and then leave them to die of the extra burn damage.

Salarian Operator: This is to prioritize the semi-auto/burst fire snipers, so you have a mattock-like rifle, that is capable at any range, it wont be as strong as the infiltrator, but because you can afford to body shot with it, or headshot as needed. It opens options for you, but you need a high level semi-auto to do this. The viper can do in a pinch, but it does leave you much more vulnerable early on to melee.

N00b Rating: (scale 1-5, 1 is easy for everybody!)
4.5. This build is very high risk, you are very fragile, and because you are using just one weapon, a semi-auto sniper at usually close to medium range (Map depending), scoped and not, that you need both high awareness, and very good dodge skills to hit the fastest cover possible when anything so much as starts firing at you. If someone gets into melee range with you, you have few options, and are very likely to be tasting concrete. Lacking fitness, is painfull for a while, and takes alot of getting used to. Decoy’s range is short, so if your not carefull, you can be easily shot if your decoy drops unexpectly, or you are moving up when you start taking fire.
