Welcome to my brief primer on how to win all 3 scenarios as O'Toole. This description contains SPOILERS in the descriptions below.

General Overview:

Skids is pretty average at everything, which makes me great for taking on all 3 scenarios solo:

Money: Emergency Cache, Burglary, and his broken Elder Sign trigger.

Damage: Machete, Vicious Blow, Backstab, Dynamite Blast, and Sneak Attack, mean you are a damage dealing machine. Don't use any of the other weapons. Machete is the best.

Health: Generally you will not take very much damage with Dodge, and Elusive and some damage absorption on Leo De Luca. Your high evasion keeps you safe. Low Willpower is dangerous, so 2x Physical Training will ensure you don't go insane to Treacheries.

Investigation: Skids has decent investigating at 3, and most scenarios do not need more than a Flashlight and Perception to beat solo.

Mulligan Strategy: Hard mulligan for Leo De Luca. He wins games by himself. Other cards I keep are Emergency Cache, Flashlight, and Machete. Everything else can go back except for in Scenario 3 (explained later).

Scenario 1: Generally a cakewalk for Skids. No real strategy needed. Save a Backstab or Sneak Attack for the priest and you will be fine. Save Flashlight for the Cellar.

EXP: Spend on 2x Leo De Luca, 2x Hot Streak (or 1 if you can't afford both). Replace Leos and Emergency Cache or Burglary.

Scenario 2: Now the real game begins. Try to get out Flashlight, Machete, and Leo De Luca. Our main goal for this scenario is to kill the dude who comes out of the first agenda, and maybe 1 or 2 other cultists. I have found that killing all 6 is completely impossible solo, unless you get incredibly lucky. This will not affect us in scenario 3, so don't worry about it.

Once you've killed the cultist who comes out of the agenda, it is CRITICAL that you resign before hitting the requisite amount of doom on the second agenda. You do not want to let it trigger, as it causes you to lose 2 cards at the beginning of scenario 3.

EXP: Personally, I only killed 2 ghouls here and received 2 EXP after my failed Hospital Debts. I had one EXP remaining from the previous scenario and opted to get 1x Sure Gamble for scenario 3. I replaced a Burglary.

Scenario 3: Here we are. The main event. Hard mull for Leo De Luca, Dynamite Blast, Vicious Blow, and Machete. Nothing else matters very much. Physical Training is nice to see early on.

My strategy for this scenario is as follows: Phase 1: Stay in the starting location and draw cards, gain resources, and play assets. Do NOT move around and look for clues. It is a waste of time and will just spawn more enemies. You are looking for 2x Dynamite Blast, 2x Vicious Blow, 1x Machete in order to win the game. Then, you need to save up resources to be able to play all of those cards. It also helps to have Dodge or On the Lam for the final turn.

You will draw enemies and horrible treacheries. Try to float some cash and play Physical Training to counter the terrible Willpower treacheries. Evade and move to any Woods when you draw an enemy. If it has hunter, kill it instead.

Phase 2: Make sure you get Physical Training for the horrible trigger of Agenda 2. You do not want that to happen.

Phase 3: Once enough doom accumulates (along with some acolytes in random forests), you will trigger the spawning of the boss. At this stage you need to have the cards in your hand and enough resources to play them. You also need to be in a Woods (preferably with no enemy). You now have one more turn to prepare while he moves into the main path from the ritual site. Once he moves into the main path, you are going to do the following:

Play 2x Dynamite Blast for 6 damage. Move into the Main Path. Attack with Machete and use 2x Vicious Blow. Ideally, you will also have Sure Gamble to ensure a win here. If you draw a Tentacle Chaos Token and auto lose, then the Elder Sign gods are not with you.

This will deal a total of 10 damage in 4 actions (which you should have with Leo De Luca or by using your ability).

If you made it this far, congratulations! If something ruined you in Scenario 3, just try it again.

Final note: If you have the weakness that discards all your resources or your hand, you can try this strategy, but you will probably fail. Bad luck!

I hope I helped some people beat Scenario 3. Good luck everyone! Let me know your thoughts in the comments. Love this game!
