I'm currently around 69 turns deep into a getai missions and I'm a bit stumped on the missions. The new player guide has been helpful and I have taken a peek on the campaign script, unfortunately the techno mumbo jumbo is too much for my smoothbrain. So I hope somebody can help me figure things out and we can craft some sort of a complete guide similar to the baktrian reforms.
Here's what I've gathered so far:
1. Keeping Our Word
Obtainable from: The start of the campaign
Condition: Take Klepidava, Region: Tyragetia (the region north of getia)
Required for reform?: No
Rewards: 1 skythian HA, 1 getai HA, and moskon will not defect
Notes: If you still haven't took klepidava after 30 turns, you'll receive a reminder to finish the mission. And I think if you still fail to do so after certain turns moskon (your FH) will rebel with a large army
2. A Cry For Help
Obtainable from: Taking Zikideva, Region: Moisia (directly south of the getai capital)
Condition: Take Singidunon, Region: Landa Skordiskoi
Required for reform?: YES
Rewards: 2 galathraikes
Notes: After you took Zikideva (and received the cool new "Liberator of Moisia" trait), a rebel celtic army would spawn simulating the scoridici raids, I believe they will appear from time to time until you finish the mission. Moving your army near or besieging Singidunon would also trigger a garrison script.
3. Becoming Protectors
Obtainable from: ???
Condition: ???
Required for reform?: YES
Rewards:???
Notes: I'll be real dawg, the next couple of missions confuse the heck out of me. It either has something to do with killing enough skythian raids that would spawn on histrie, triggering a large scale invasion, or taking histrie and triggering a scripted unrest event? Either way beat the large skythian stack and you'll get this.
P.S. taking olbia and skythiapolis would end the skythian raids, so don't be dumb and misread the script like me, leave those horsey bois alone.
4. The Northern Invasion
Obtainable from: Sacking Streuinta (Boii capital, region: Boiotergion), or Noreia (Region: Etunorikoi) while holding Kapidava and Zikidava
Condition: Beat the two scary large bastarnae stacks
Required for reform?: YES
Rewards: The reform, Duh.
Notes: Thankfully this mission isn't that hard to read to my untrained eyes. Unfortunately I haven't made it this far to the campaign and I can only tell you what I think I saw. I'm not too sure on Noreia but the option is nice so you can choose your final boss for the reform to be either the boii or the bastarnae.
P.S. to unlock the reform you also need your FL to have either the living legend trait (7 authority I think?), but at this point if your starting FL is still alive he'll easily pass through the bar with flying colors.
