As Daemon Sultan, you need to react to what’s going on. Because of this nature of your faction, you can’t just make a plan from the start and stick with it. You have to be able to respond to the situation. This is really obvious right from the start, while you are placing your first, free, cultists using Psychosis. Where do you put them?
And when do you get your spellbooks? This is core to any faction. So let’s examine your spellbook requirements, and when you can take them.
One of each type of larva. There are three types, all of which cost 1 Power each. Since you need a gate to summon them, you can’t get this in the first turn.
An abandoned gate is on the map during Gather Power. In theory you could do this in the first Gather Power – if you are the last player, you can just abandon your gate. I wouldn’t recommend it though because you’ll be starting turn 2 with a bad power differential. And then someone will steal your gate first thing next turn. Instead, wait till you have Chaos Gates, and abandon one of them.
During the Doom phase, each other player gets either 1 Power or 1 Doom, and you get what they get. Again, you can’t get it the first turn, but you could kick off your second turn with this boost.
Awaken your Great Old One – you have three to awaken. Sadly, you can’t awaken any the first turn. Do the math. Building a Gate costs 3 Power. Summoning a Larva Thesis costs 1 Power. Now you’re out, and can’t take any more actions. Exception: if you can talk Sleeper into giving you a Power boost in the first turn, you can awaken Avatar Thesis. Lots of luck.
The bottom line is you’re at most going to have one spellbook as your second turn starts (the one where everyone gets Doom and Power). Early on, you can awaken Avatar Thesis, for 0-2 Power easily enough, for a second spellbook. Then build from here. But let’s check this out turn by turn. Let’s say it’s a 5 player game.
You have 4 Power and 0 Doom.
You recruit a cultist somewhere free, and keep doing this until you have at least 4-5 cultists in play. One or more might get captured. Obviously it’s good to avoid this if possible, but c’est la vie. It’s cheaper to recruit a new cultist than to defend one. You need to build 1 gate and summon 1 Larva Thesis this turn. That’s all four of your Power. Don’t do it till the end of the turn, when the other players are low on Power, so they don’t know where you’re going to be setting up.
You have 1 gate, and let’s say 5 cultists out. This gives you a start of 7 Power and 1 Doom. In the Doom phase you get your “everyone” spellbook. Let’s assume two of the other players took Doom and 2 took Power. This bumps you to 9 Power and 3 Doom. A logical spellbook to take is Animate Matter.
Animate Matter (Action: Cost 1) Flip this spellbook face-down. Move a controlled Chaos Gate from its Area to an adjacent Area, taking its cultist along. You cannot move to another player’s Start Area. If the new Area has an existing physical Gate, replace that Gate with the Chaos Gate.
As one of your first actions, you then create a Chaos Gate for 1 Power, following up with a Larva to guard it. You have 7 Power left, and now two guarded gates. You can now awaken Avatar Thesis to whichever gate seems more threatened. If you think you need more monsters & cultists, get a cost 0 Thesis. If you want a tougher Thesis, spend 1-3 Power on it. Say you get a 2 Power thesis. Now you have 5 Power.
