Interesting, are there any other cases where force weapons performed in a less than amazing fashion?
Its worth bearing in mind that Khanjar the Sharp was built by a Tech-Priest reknowned for his specialisation in materials science, and that what sentience /soul Khanjar had wasn't going to be present in that body.
As I posted earlier, Angron wasn't particularly bothered about manhandling the blade of one, and it should have burnt his fingers off wielded by a GK like Aurillan.
I wonder what the diffrence of the machine would make in the running of the "machine spirit" considering these things are considered sentient, so a Warhound might have a limited spirit but with a diffrent mentality governing it like giving it behavior more suited to scouting where as a Warlord would take a much wider perspective on the battle as it has more destructive power at its disposal, and on the extreme end the Warmonger whitch could be far more active the the Warhound as it only has a single pilot for the whole Machine.
The machine spirits are "imprinted" initially with animals from ancient earth, Warlords usually got Grizzly bears IIRC, Warhounds got wolves/pack hunters, it was even mentioned that possibly other aggresssive alien beasties might be used for future titan designs. (obviously a fairly early feature)
Then the titan would continue to gain experience as it bonded with various pilots.
From what I've heard the Orks sometimes use their Alpha-level psykers as capital ship lance-analogs. Is this true?
I think it was an upgrade, a Strength 1 or 3 lance battery, resulting from a Weirdboy tower being added to your ship.
So its probably not a single ork, but a bunch of Weirdboyz chained together. That appears to how they operate, the short story Liberation day features a load of Weirdboyz chained together being used as a Navigation system by an Orkish spacehulk.
What happens if two power weapons hit each other?
What if they're of exactly the same model of weapon, wielded by warriors of equal strength?
Usually its has been posted, lightsaberish clash, flash of energy and sparks flying etc.
There is one example in Crusade for Armageddon or its sequel where a power sword and power claw briefly overload after a sustained and violent clash, but they flicker back on again almost immediately.
