Hi, all! I worked out what I believe to be a solid journey to Mythic and to become a solid contributor to my guild's raids. I only recently got my act together in Tacticus, though, so I thought it made sense to post my plan here and see if anyone could punch holes in it that I might have missed. 

The Goal: To have a mythic D1 Neurothrope raid team of Neuro, Ahriman, Abraxas, Archimatos, Eldryon, and Z'Kar. I admittedly do like this team for somewhat sentimental reasons, as I play Thousand Sons on tabletop and love psychic Tyranids, but it also seems to be the ideal meta raid team for me based on my roster. My best campaigns so far are Saim-Hann, Saim-Hann Mirror, and Fall of Cadia, so Abraxas, Eldryon, and Archimatos are already 3 of my best characters. 

Stage 1: Level the core 3 characters (of my plan, not the raid team) to blue star D1. 

Side Goals: Unlock Ahriman, Thaddeus Noble, and Mephiston. Due to a combination of codes, pulls, and questionable past decisions, I will be able to finish unlocking Ahriman as a result of the 4th anniversary event. Thad is needed to unlock Fall of Cadia Mirror. Use Guild War tokens and Anniversary event shards to unlock Mephiston over time.

Also, get more Neurothrope shards from the anniversary event. It's the easiest source of shards, and it'll pay off later.

Step 1: Focus on Eldryon to blue star D1. I need Eldryon at a high level anyway as the campaign carry for Saim-Hann, and I need to 3-medal Saim-Hann Elite in order to efficiently farm Abraxas and Ahriman shards later. In addition, I have his Elite stage 3-medaled and he can be bought in the Guild Raid shop, so his shards are by far the easiest to farm of the core 3. 

Step 2: Level Astra Militarum, Bellator, and Calgar enough to 3-medal Archimatos's Fall of Cadia Mirror Elite node. Selecting Bellator and Calgar specifically will pay off later.

Step 3: Focus Archimatos in the same manner as Eldryon. He's useful as a Book holder as well as a campaign carry in Fall of Cadia and Saim-Hann Mirror, and at this step his shards are as easily farmed as Eldryon's. 

Step 4: Level Calandis and Aethana enough to 3-medal Abraxas's Saim-Hann Elite node. 

Step 5: Focus Abraxas in the same manner as Eldryon and Archimatos before him.

At the completion of this stage, the core 3 cast are at blue star D1, if not yet Mythic, and serve as a powerful Psyker core as well as sources of easily-farmed Archeotech. 

Stage 2: Level Neurothrope and Ahriman to Mythic D1.

Step 1: Level Orks to advance Octarius Elite. Large swathes of necessary Tyranid upgrades lie in this campaign, and the Orks are key to getting there. If I recall right, I need to 3-medal up to node 26 for all needed Tyranid upgrades to be efficiently farmed. Regardless of the specific node, though, this is where I need to go. 

Step 2: Level Incisus, Bellator, Titus, Calgar, and Mephiston to D1. This team is needed to clear out and 3-medal CE Tyranids Extremis, giving me access to efficient Neurothrope farming and a Norn Crown. 

Step 3: Level Neurothrope to Mythic D1. At this level, I will have a functioning (if suboptimal) raid team of Neurothrope, Abraxas, Archimatos, Eldryon, and Yazaghor while I level Ahriman.

Step 4: Level Calandis and Aethana enough to 3-medal Ahriman's Saim-Hann Elite node for efficient farming. 

Step 5: Level Ahriman to Mythic D1. Fairly self-explanatory based on the rest. Bring Ahriman up to become a functional and highly contributing member of the raid team. 

Step 6: Level Z'Kar to Mythic D1. Fairly self-explanatory based on the rest. Bring Z'Kar up to become a functional and highly contributing member of the raid team. 

  
As of now, I believe this to be a fairly solid long-term plan based on my own knowledge of the game, but want to post here to see if I missed anything. Comments and criticism are not only welcome but greatly appreciated!
