Alright, let's talk about the Sentinel class in Mass Effect. These guys are pretty solid all-around, especially when it comes to personal defense. They can handle Barrier, Shield, and Armor pretty effectively even without special training, and they eventually get access to the awesome Warp ability. The downside? Their starting weapons aren't the greatest, and they don't get any natural ammo powers, meaning you'll have to invest points to unlock Warp.

For a Level 30 build, I'd recommend something like this:

• Throw: Level 2
• Heavy Warp: Level 4
• Power Armor: Level 4
• Overload: Level 3
• Cryo Blast: Level 0
• Raider: Level 4

When it comes to Advanced Training, you've got a couple of good options. Squad Armor Piercing Ammo (4) or Squad Warp Ammo (4) are both solid choices. Since Sentinels don't have their own ammo powers but tend to rely on their weapons more than Adepts or Engineers, getting an ammo ability is a really good idea. Warp Ammo is especially useful on higher difficulties because enemies have so much defense. With Warp Ammo, you can just keep firing and get that bonus damage. Armor Piercing Ammo gives a bigger damage boost, but you'll need to strip shields with Warp first before AP ammo really shines. It's a trade-off, really.

As you're leveling up, your main focus should be on maxing out Warp, your passive class ability (Raider), and Tech Armor. You can get by with fewer points in your Advanced Training and Overload early on, but having a few points in those abilities can make you more versatile from the start.
