Magic and Steam as higher tech

End game really needs power.

First, steam:

Basic items:

• Steam boiler
• Steam pipe (modular)

Utilizing items:

• Steam powered workshops (work much faster)
• Steam heaters
• Steam traps (cook enemy)

Then, magic:

Basic items:

• Magic source (charge crystals with moonlight or ritual sacrifice or something)
• Magic conduit
• Magic storage (a big crystal from the depths of the earth). Magic would be slow to generate but you can compensate with storage?

Utilizing items:

• Magical work benches. These would differ from steam powered ones in that they work better, not faster (higher quality output)!
• Magical lights
• Magical defenses
• Magical space heaters and coolers
• Portals would be cool, to teleport around your base

So the progression would be:

Manual operation -> Steam operation -> Magical operation

With enough differences between steam and magic so both have their place, coexisting in the same kingdom.
