Class Skills / Class Specialization

Jack of all Trades
Learn all skills on a single skill tree in one playthrough

This is best done near the end of the game. I got it by spending at least one point on each of the Cavalier’s possible skills. I tried the same thing with an Apothecary but it didn’t pop.

Core and Advanced Specializations

A Well Rounded Military
Get all Core Class specializations across troops

Military Mastery
Get all Advanced Class specializations across troops

With regards to these 2 achievements:

Core = Basic Classes (Cavalier, Apothecary, Etc)
Advanced = their Promotions

There are 9 Core Specializations:

Cavalier = One-Handed / Two-Handed
Apothecary = Field Medic / Corrosive Concoctions
Warmancer = Path of Flame / Ice / Lightning
Ranger = Bow Mastery / Crossbow Mastery

There are 16 Advanced Specializations (4 Core Classes * 2 Promotions * 2 Specializations):

Cavalier
- Inquisitor = Holy Reckoning / Aura of Light
- Ronin = Wandering Soul / Trance Arts
Apothecary
- Monk = Furious Blows / Arcane Energies
- Shaman = Cosmic Overseer / Darker Paths
Warmancer
- Druid = Nature’s Harmony / Manipulate Earth
- Sorcerer = Wild Magic / Touch of Death
Ranger
- Hunter = Death from Above / Guerilla Tactics
- Reaver = Dagger Arts / Hired Assassin

To get these achievements, you need at least 1 of each Specialization concurrently. You’ll know that a unit is specialized if they have the Specialization text under their respective Class/Job

You can complete both achievements as soon as level 19 since you only need to spend as little as 1 skill point in the Advanced Classes to pick a specialization. This means you’ll need at least 16 differently specialized recruits (Uniques included) to earn Military Mastery.

Overworld

Contracts

Mercenary for Hire
Completed 5 tavern contracts in a single playthrough

Tavern → Chatter

Sword of the People
Completed 10 tavern contracts in a single playthrough

Of Red Pandas and Trash Pandas
Recruit Lefty

In Chapter 3, there will be a contract related to Lefty. Upon completing this Contract’s battle, Lefty automatically joins after a heartwarming cutscene. There’s also a Contract related to Poncho in Chapter 1. I’m not sure if this is required, but to be on the safe side I recommend just completing all available contracts per chapter.

Recruited 5 units in a single playthrough

We’re Going to Need a Bigger Army
Recruited 15 units in a single playthrough

Unit Management

Medal of Honor
Promote your first unit

Despite the description, I got this after spending points 6 times as opposed to 6 points.
