Hmm.....but adding dots does not help more tbh as there are no mechanics attached to it. I mean, narratively, there is no difference between Thalassa having 5 dots and 10 dots as she already has the max knowledge the Cult Mechanicus has, not individuals but the entire Cult.
The reason to do it would be to symbolically represent the heights of knowledge the DAoT reached.
Sure, five dots represents the full knowledge of the Mechanicus in a field, but the Mechanicus only know scraps and are unable to comprehend or even make copies of more advanced DAoT tech; and certainly can't make the better Eldar or Necron tech.
Basically, the way I'd do it is say that there's a new background called Archeotedh, similar to Artifact, that refers to rare technology. A Savant rating would represent the knowledge required to make Archeotech items within a field. I'd make it something like:
Archeotech 1-5: would represent the range of Archeotech the 30K Mechanicus can replicate
Archeotech 6-8: would represent simpler Eldar and the full range of DAoT equipment
Archeotech 9: would represent the peak of Pre-Eldar and post fall Haemonculi conventional tech (like transforming people into sapient beams of light without using psi-tech), most of its high end Pre-Fall psi-Tech, and most Necron tech
Archeotech 10: would represent Old One tech, the peak of Eldar psi-tech like Reality Engines and Deep Warp taps, and the peak of Necron Tech like the Celestial Orrey.
I'd even be tempted, given the range of tech, to stretch this out to 20 rather than 10, and do the same with things like Resources, Followers, Retainers, Spies, etc
I'd do this to represent the vast heights of technology people in the galaxy have reached, much greater than a five point scale represents.
I'd also this to emphasise how much there is to learn and to give something for her to learn once we're on the galactic scene, even if we're capped to granting five dots.
In 40k this may backfire as many things there are powerful enough that they do not need common sense.
I also do not like it as it....
1. Inhibits player choice
2. Puts a burden on my to spoil things
3. I already warn you guys if a choice or write in is safe or not.
So it does not seem that good tbh.
I've said it before, but the people we should grant this to are small children, as a mercy to their parents.
I answered the first before. He is human so no, it cannot form the base of his worldsoul.
For Anathdma, Lorgar has just started on it and does not even know he has it.
That is the extent of what he knows.
Although we can't have it as the foundation for a World's Mythos, can we use it as an ingredient to add a flavour to it, as Lorgar could be a big part of the narrative of the world being cleansed and its propitious redeeemed and the World Soul being reborn
Shame we didn't pick the Destruction and Rebirth aspects for Dharok, as it would fit in very neatly.
Minor, we could have him parry/dodge and attack in the same turn without the dice penalty.
The thing that lets you do more things is the Extra Speed Mutation
Extra Speed
3/6 Points
The fomor can outmaneuver a normal human.
System: For every 3 point (up to a maximum of 6), the fomor may take one extra action per turn without splitting her dice pool. When moving, this allows the character to multiply a normal human's speed by 1.5 for each three points spent.
It literally lets you do more in a single turn.
I doubt it would work on a strategic scale though, and I'd expect space marines to have at least the lower level version and Primarchs probably both based on how quickly they're described as being able to think and act.
It's something I want as part of our own genetor package though.
