Leveling engineering for faster sieges and better engines.
Engineering Skill Leveling
Leveling Engineering can feel like a grind if you rely solely on building siege camps. However, with the right tactics—specifically in siege defense—you can power-level this skill from 0 to 200+ in a handful of battles.
The XP Formula
You gain Engineering XP from:
Construction: Successfully building a siege engine (Campaign Map).
Operation: Dealing damage and getting kills with siege engines (Battle Map).
Projects: Completing buildings in a settlement (Governor).
The Active Operation method is by far the fastest.
Manually operating a ballista or catapult yields significantly more XP than letting the AI do it.
Method 1: The Siege Defense Farm (Fastest)
This method requires you to wait in a town or castle that is about to be besieged.
Break In: Enter the settlement before the siege begins (or break in, sacrificing some troops).
Build Engines: Prioritize Fire Onagers or Ballistae.
Take Control: When the battle starts, take control of an engine.
Target Clusters: Aim for the enemy battering ram or siege towers where troops cluster.
Result: You can get 50-100 kills in a single siege, granting massive XP.
Defenders have infinite ammo, allowing you to farm XP until the enemy retreats.
Method 2: The Campaign Loop (Passive)
If you prefer playing the map:
Besiege a town.
Build 4 Trebuchets.
Move each to "Reserve" as soon as it finishes.
Once all 4 are done, deploy them to destroy enemy walls.
Do not attack. Lift the siege and repeat on another town, or let the engines be destroyed and rebuild them. Note: This is slower and costs influence/food.
Optimizing Your Character
To level fast, you need Intelligence.
Attribute: Put at least 5-7 points into Intelligence.
Focus Points: Max out Engineering focus points (5/5).
With high Intelligence and Focus Points, you can learn Engineering at a accelerated rate.
Summary
Don't rely on your companion for everything. If you want to be a master builder, jump on that Fire Onager and rain destruction on your enemies. It’s the most fun you’ll have leveling a skill in Bannerlord.
