Use Oops! to deal damage against enemies with: High value; Retaliate; Aloof; or who are engaged with another player. Engage with and attack another enemy with a lower Fight value (the ideal would be a Fight of 2, since it would be impossible to fail the attack by more than 2), without Retaliate, or who are not Aloof.

Do so without bonuses of s / icons, preferably using an attack with a natural Damage bonus (i.e. not one that depends on the attack being successful), and better still not using your investigator's better skill-values. Thus favourable choices (when available for the investigator's deck) are: Backstab; .32 Colt and Shrivelling [also Knuckleduster though this will result in the initial 'phoney' target doing its own Retaliate damage to you].

Since damage dealt by Oops! is not the result of an attack on the "target", failure now results in damaging the higher Fight-value enemy/bypassing its' Retaliate/avoiding risks of injuring another player already engaged with it.

This can be a directed tactic or merely to hedge bets facing multiple enemies. It is more practical cooperating with fellow players; and when your deck and/or that of a team-mate includes cards apt for bringing weaker and stronger enemies together and/or engaged with the attacker (e.g. Shortcut; "Let me handle this!"; On the Hunt; Taunt; Heroic Rescue).

Not a review or anything, but having mentioned this via the GutHub link at the bottom of the page, which seems to have gone unnoticed, I'll mention this here in the hope of correcting an error.

The encounter set included in Carnevale of Horrors, is actually called 'Carnevale of Horrors', not Venice as listed here on arkhamdb.

This card actually says: You lose an action. Other investigator may take an additional action.

Well i don't know if this is good or bad card to include it to your deck. As a seeker in multiplayer you need every action to gather those clues so i'm kinda meh...

I was extremely excited when I first saw this card. I thought I was going to immediately buy it in every Rogue deck I ever played. XP is incredibly powerful and fun in this game, after all. But the more I play with this card, the less I like it.

The odds that your character dies at some point in missions 2-7 of your campaign (if they die in mission 1 or mission 8, that's not really relevant for the Obol) are just way too high. Even if you run "I'm outta here!" and Cheat Death, I just think the risk is too great. Starting over midway through a campaign at 0 XP is a truly terrible feeling. In solo, maybe it doesn't feel quite so bad, but I really would not recommend this in multiplayer.

Note that "I'm outta here!" is far from a perfect failsafe here. Many scenarios don't have a resign space or have one that doesn't show up until the final Act. It won't save you then.

Moreover, Charon's Obol can also hurt you even if you don't die. This is because the Obol makes you play scared. Vastly increasing the consequences of dying makes it harder to play effectively. A very common situation in this game is the following: your investigator is severely hurt, down to 1 or 2 health or sanity remaining, but only a couple of turns away from a potential victory. What should you do? A normal investigator can go for the win. Sure, you might take a trauma, but that's not really a big deal at all. And you might win! With the Obol, you can't really do that any more. The consequences of defeat are too high to take otherwise profitable risks.

Furthermore, playing the Obol can force you to stuff your deck with durability cards (like the aforementioned "I'm outta here!" and Cheat Death), at the expense of better cards that actually help you win the scenario directly. This hurts your deck and can mean that your deck's power level isn't that much higher than a deck that doesn't run the Obol, but also doesn't have to run these cards.

Still, I can see the temptation here. If you like the thrill of risk and are OK with a strong chance of having to starting over, go ahead. But personally, I find the game much less fun when I'm running the Obol. And setting considerations of fun aside, if I were just trying to maximize my odds of winning the campaign, I do not think I would take it.

This card gets very broken with Sefina especially when combined with pickpocket lvl 2. One of the best combos we've found so far for it. Keeping elite enemies locked down whilst the team gets work done
