Horus Heresy 3e Review: Contemptor-Osiron Dreadnought

Warpstone Flux Rating: 
⭐️⭐️⭐️
3/5 stars. The result of putting psykers in dreadnoughts!

Background.
The result of Magnus The Red's magnificent mind to solve the problem of interring a psychic warrior inside a dreadnought to serve still. The Thousand Sons legion was the first to field them and freely gave the tech away to the other legions who appear to have spurned the gift. Maybe not the Alpha Legion though?

Strengths. 
Rule of cool applies: psychic dreadnoughts for the win!

Alongside all the usual dreadnought upgrades, you also get to buy 1 psychic discipline and have a force sword that has reaping blow.

Weaknesses. 
Costs lots of points already and you're only getting WP+1 and a force sword (which to be fair is very very good) compared to the baseline dreadnought which is why it gets 3/5 stars from me. It is over-costed. But it is still very cool! 

Builds.
Osiron, Kheres Assault Cannon, Divination (235 points).
Dakka combined with preternatural foresight. 

Osiron, Melta Cannon, Melta Gun, Telekinesis (250 points).
Why not? Because of the points cost is the likely answer here to be fair. 

Osiron, Conversion Beam Cannon, Havoc Launcher, Pyromancy (235 points).
Lots of bits to play with. Not necessarily all overlapping though - NB.
