While I heavily appreciate and am pleased to see that someone enjoys my lore enough to try and take it in a new direction and explore more possibilities, I have to say that I disapprove of this addition. I have many reasons for this, and I'll go into them as follows:
Cognatism in and of itself is a 'Self Roleplaying Magic'. It is supposed to be purely developmental and internal, and provide no benefits to combat outside of enchanting capabilities. This is made this way because we felt that there were too many combat orientated magics and wanted one that was purely designed to function and enhance the individual's and those within the vicinity of the Cognat's roleplaying experience with Magic. It is a staple of Scholarly pursuits and should remain that way.
Months ago, I attempted to write and submit an addition to Cognatism known as 'The Mind of the Horror' which expands upon the nature of the Horror, the interactions one has with the Horror, and a Prismal Loop that essentially allows for a character driven story which can be written and posted on the forums for Character Development in the same vein as the new Arcane Displacement/Shunting lore. The reason that this was denied was because Cognatism, in a nutshell, is way too large to even really be considered a feat.
Cognatism should, for all intents and purposes, be a full-slot magic. The only reason this is not the case was due to the fact that no one wanted Cognatism as they focused more on SoyBoy Magical Nutbags who had all kinds of devastating combat magic as opposed to those which enhanced the roleplaying experience. We settled on keeping Cognatism a slot because that is where it will shine best and people will actually take up the Art due to it not taking one of their precious slots. Any form of addition will certainly bump it up in power and force it to become a slot magic once again.
After reading over the Lore, and having a conversation with someone who cares about Cognatism and the way that is is roleplayed, we came to the conclusion that if this Lore was to be submitted or accepted, that instead it should be an addition or post-feat to Arcane Displacement/Shunting. Should the new submission by Zarsies (Bae) get accepted, this could act as an additional feat which requires Displacement/Shunting as a prerequisite to acquire. Both act in forms of altered dimensions, one from a very individual character driven standpoint and one from a combat one.
As I said before, Cognatism is a very internal magic. Not just in the ways of Self-Roleplaying, but in the way that it interacts with the world. Cognatism is supposed to be an enhancement and aid to the mind of a character, not to their magical or physical capabilities. The Horror never actually teaches the Cognat something, it simply soaks the information in response for an optimised mental state. The Horror does not, and will never really care about the Cognat enough to actually give them more command over spells or the void in this way because they can simply find someone else to feed them that knowledge. Horrors are not like the Shade Parasite, and they do not die if their 'host' dies. They live on, and are able to select another to establish a connection with.
As I said before, to see that someone cares about my lore enough to make an addition is warming and I appreciate that, however this lore does not fit into what Cognatism was, is, or should be. For that reason, I am against this addition and believe that it should, as suggested above, be it's own individual feat unrelated to Voidal Horrors, or instead be involved with Arcane Displacement/Shunting. If you really wish to work on an update to Cognatism or an addition which provides nothing too extensive to bump it from it's shaky ground as a feat to a full-slot magic, then feel free to contact me and I will gladly work with you on such.
TL;DR, this is not what Cognatism is about, and should not have any kind of combat advantage. -1
