Specialist is a Class or Specialization in XCOM 2. You can train a Soldier to be a Specialist in the Guerrilla Tactics School in 10 Days. Specialists are your technical experts in the field. They employ advanced robotic drones that can hack systems or heal players.
"Operating some of our most advanced equipment. Specialists deploy robotic drones on the battlefield that can be outfitted for combat or field medic duty."
Specialist are perhaps the most versatile of all the Soldier Classes. Because they can specialized in healing or offense, it is highly recommended that you take 2 on every mission after you've acquired at least one more squad member space per mission. It is recommended that you make a couple Battle Medics and a couple Combat Hackers, so that you can deploy one of each for every mission, and have backups in case one or both of them get wounded.
- If possible position your Battle Medics in the center of your field of vision, meaning, don't put them on your right or left flanks, but try to keep them towards the center if you can.
- Make sure your Battle Medics always have a Medkit. The Field Medic ability will allow them to get 3 uses per Mission, making them the most efficient Soldiers to carry them.
- Combat Hackers generally shine later on in the game then they do at the beginning, as enemies tend to get more and more Armor. Their Combat Protocol ability bypasses this Armor and it deals DOUBLE damage to Robots, MECs and Turrets (which usually have the most Armor of all units).
- Target enemies with Combat Protocol that you know you can kill, or that other squadmates most likely won't be able to hit because the hit chance is too low. This abilitiy is a gauranteed hit and has extremely long range.
- Use Aid Protocol LIBERALLY. This is one of the best defensive skills in the game (if not the best) and it will help keep your front-line troops from being killed when they are being attacked by several enemies. The cooldown on it is relatively short, so use it whenever you think someone might be under attack, and especially if they aren't in Full Cover.
- Avoid hacking if the chances of failing are above 50% because failing Hacks can often make situations DRASTICALLY worse for your squad. The exception being if the reward is a permanent +20 Hacking increase for your Specialist. ALWAYS attemp those.
- Some Missions require you to hack a terminal as part of the objective. Your Specialists can do this from afar with their Gremlins if they have line of site. It's a good way to Hack them without endangering a squadmate needlessly. You can also be rewarded with other goodies if your Hack skill is high enough (including +20 Hack permanently), so when possible always use your Specialist to do this.
- For Personal Combat Sims, just about any will do. This Class will probably benefit the least from any, so make sure to slot your other Classes with them first.
- For Upgrades, just about any will do. It's always a good idea to get one that increases Mag size or gives you a free reload or two, however; it can make all the difference.
