Pros

• Fast and cheap
• Will help you recover at least 1, often 2 Sanity
• Can heal other investigators at your location; so spread the love around. Remember, you can take your investigator turns in any order, so it's easy to set up
• Has both a Combat and a Willpower skill token, so it's never useless
• Gruesome artwork. What did you DO to that creature?

Cons

• You need to kill a monster, and preferably one with a medium to high horror value

This is a card clearly designed to help low sanity guardians (Zoey and Roland) survive their romp through the horrors of Arkham. The added bonus of healing your friends is just icing on an already delicious cake and fits with the guardian theme of leading from the front.

How is "If it's bleed..." compared to other sanity restoring cards? First Aid takes 4 actions to heal 3 Horror for 2 resources, but can also heal Stamina damage. Moment of Respite (sort of the opposite to this card) restores 3 sanity and a card, but costs both Xp, 3 resoruces and an action. Smoking Pipe restores up to 3 Sanity, but at the cost of stamina and one action.

This card is superior, I'd say, as long as you kill 2 horror value monsters. Which I bet you do twice, before breakfast. =)

"Fire in the hole.”

Rita was awed by the psychologist’s flat affect. It has been kind of upsetting, that Peter would hang out with her instead of a fellow Squid, but she could understand it now.

Joe Diamond, no stranger to these types of cases, ducked behind the couch. Sure, it all started as “stick to the plan”…But he saw those red sticks peeking out of Carolyn’s purse.

“You know Di is in there, right?”

The explosion was a hell of an answer. Whatever ghoul the circle had dreamt up was now decorating the parlor.

As Diana emerged, her robe slightly singed, Dr. Fern lectured the group on witchcraft and its role in protofeminist gatherings.

Everyone felt better that they weren’t her.

Not a fan, has too many things going against it.

1. You need to defeat a Monster enemy only. You won't always find one of those.
2. You need to defeat the enemy, not another investigator.
3. You need to have card in hand, and 1 resource at the time (guardian's tend to run low on resources)
4. The enemy must have horror value, there are some that don't (but fortunately, most Monsters do, maybe 75%)
5. You only heal 1-2 horror on average. Usually only bosses give 3 and if you're killing a boss you probably don't need the horror heal anymore.

If you can/own the cards, you're probably better off playing Book of Psalms, Hallowed Mirror, or Medical Student
Out of faction, you can try Logical Reasoning, or Fearless
