Engineer
You will unlock the engineer when you reach character level 50. With the engineer can inspect, upgrade and equip your war machines and set up your battle formation. The engineer building has the following three parts:

Engineer level
Your engineer levels-up by gaining engineer xp. Whenever one of your war machines gains a level, the engineer gets 100 engineer xp. The xp requirement to level-up the engineer starts at 600 xp for level 2 and increases by 50 xp per level. Each engineer level increases all attributes of all your war machines multiplicatively by 5%:
engineer bonus = 1.05(engineer level – 1) - 1
Every six hours you can claim tools from the engineer. The amount of tools you can claim increases with the engineer level as follows:
tools = 225 + 25 × engineer level
Squad
In order to fight in battles you need to select a squad of war machines. You can set up three different squads and select one of them as active for use in the Warfront Campaign and in the Arena of Kings. Each squad contains up to five war machines. Each war machine in your squad can also have a crew of heroes. The maximum number of crew members per war machine is determined by the engineer level:
| Maximum crew | Requirement |
|---|---|
| 4 members | - |
| 5 members | engineer level 30 |
| 6 members | engineer level 60 |
Each crew member increases each attribute of the war machine according to the hero's specialization and the hero's jewels:
crew member bonus = (1 + specialization bonus) * jewel bonus
The specialization bonus is 40% if the hero's specialization matches the attribute (damage specialization matches damage, healer specialization matches health and tank specialization matches armor) and 0% else. The jewel bonus is the sum of all the hero's jewel effects for the attribute. If the hero doesn't own any jewels for the attribute, the jewel bonus is 40%. The crew bonus of each attribute is then the sum of the crew member bonuses for the attribute:
crew bonus = crew member 1 bonus + crew member 2 bonus + ...
Favored war machines
When you open a jewel chest, the drawn components will be distributed in such a way that your current war machines will roughly have an equal amount of total components in the end. This means that after you unlock a new machine that machine will get nearly all components until it has caught up in total components with your older machines.
By selecting favoured war machines, you can better control the way components from jewel chests are distributed. 80% of the drawn components will go to your five favoured war machines while the remaining 20% of drawn components will be distributed among all your war machines. In both cases, the same catchup mechanism as described above will take place among the war machines getting the components.
Unlocking war machines
New war machines are unlocked with the help of arcane conduits. There are three types of arcane conduits, all of which are obtained by opening jewel chests:
| Icon | Arcane conduit | Description |
|---|---|---|
|
Chaos Turbine | Used to unlock new war machines |
|
Energy Core | Used to unlock new war machines |
|
Mana Reactor | Used to unlock new war machines |
Once you have collected a certain number of arcane conduits of each type you will automatically unlock a new war machine:
