• If you have two of these, you can use both on the same test
• However Counter Ritual can only clear one of these
• Permanent cards cannot leave play, so you can't ged rid of the doom by discarding the Bloodletting
• Use Hollow eyes or coffee to spy the mythos deck, to avoid advancing the agenda too early
• Counter spell also works against Ancient Evils
• If the player leaves (defeat or resign), the doom is removed

I played hollow eyes in my caster daisy deck in a 2 seeker game (rex was using the insecticist) and i really like her, for her static boost and ability. Knowing what encouter card is coming and preparing for it can save you.

• Compared to Scrying, activating her is a free action and she does not have charges.
• In multiplayer, you can look at the next encounter card during any player window (if she is not exhausted). So if a player draws an encounter card with a skill test, you can look at the next card. This may be helpful to protect a specific player. However if the player before him does not open a player window, her ability may be wasted for that turn.
• Tr"Ashcan" Pete's smelling salts also work on her.
• Her bonus is a good for Jim Culver's balanced stats, so he saved charges on Rite of Seeking for higher shroud locations
• Her bonus does not help agnes so much, as her is rather low. You can compensate this, with other cards, like Perception, Flashlight, "Look what I found!" or Rise.

Dealing with her doom:

• Moonlight Ritual can remove all doom on her. As a spell, her friend can find it (use Charisma to have both hollow eyes and her friend in play at the same time).
• Her ability does not advance the agenda, so her doom does not matter, if the agenda would advance the next turn anyway.
• If you discard her before the agenda advances, her doom will not matter. However she costs many ressources to play, so this is a waste. Smoking Pipe is a quick way to dispose her or her friend. You can also show her some Forbidden Knowledge to make her run away.

I completely agree with Bronze, who said:"I don't think that these protective cards are getting enough love." Just take a glance at this happy detective bragging in the office how closely he escaped a domestic dispute with his wife, and you know what i mean.

Alongside Bulletproof Vest, only two other assets are worn on the body. But the other vestments are cheaper in xp and play cost. The question emerges if and when the investment of 2 resources and 3xp pays off. For the sake of simplicity, i do not count any sanity bonuses in the ongoing comparison.

A look at the competitors for the body slot discloses the vest's shortcomings:

• Leather coat protects 2 health lesser for 2 resources less.
• Fine Clothes protects 3 health lesser for 1 resource less. And grants you a special ability.

Of course, there is the strategy of reallocating damage to other assets, so Bulletproof Vest has to be evaluated against...

• Guard Dog protects 1 health lesser for 1 resource more. Grants an additional trait.
• Hired Muscle protects 1 health lesser for roundabout the same cost as the vest. Grants an additional trait.
• Beat Cop(2) protects 1 health lesser for 1 resource more. Grants an additional trait.
• Leo De Luca(2) protects 2 health lesser for 3 resources more. Grants an additional trait.

You can play other assets to heal damage....

• First Aid heals 1 health lesser for the same cost. Requires 3 additional actions to spend.

...or events...

• Emergency Aid heals 2 health lesser for 2 resources less. Can be used on others, too.
• "I've had worse…" heals up to 1 health more for 2 resources less.
• Dodge prevents up the the same health for 2 resources less. Can be used on others.

To sum things up, under the key aspect of health protection, Bulletproof Vest is the second to best economical choice for permanent health protection available. On top, it can be combined with all other methods of health reallocation/protection/recovering. If your investigator has a low base Health or suffers from severe physical trauma, Bulletproof Vest is the card for you!

Non-body-assets in the first place give you additional, powerful abilities to cope with a variety of situations. If you plan to start a killing spree and have to tank away massive hits, the vest makes you fit for survival. It's a tool for a special role and should be valued in this scope only. Guardians can, of course, rely on their more powerful events instead or complementary. Just keep in mind that the vest is permanently there, while events are often bound to certain triggers.

Pros

• Bulletproof vest endows you with the best health bonus available, only one other card, Leather Coat, competes.
• Good play cost.
• Combines well with Scavenging.
• Great click compression, only Guardian events are better.
• -icons can alternatively boost skill tests.

Cons

• Protects the wearer only.
• Should be played before enemies appear, during a fight it's useless.
• Pretty tough xp cost, viable only for special decks.

I am just adding my review to Django's, because of a linguistic feature in the German translation of this card. German players, please beware that FFG translated "spawn" with an unspecific term (~"appear") and that Think on Your Feet does not work on enemies who just moved to your location.

Think on your Feet is pretty similar to Elusive. It takes a bit of finesse to use, you want to make sure you are ending as few turns as possible in locations you want to spend more time at. In the ideal application, this event moves you to a better location and spares you multiple actions dealing with the spawned monster. If you are unarmed and draw a monster, you can play Think on Your Feet to step away, which gives you one whole round to properly prepare for fighting.

The benefit of this cards mainly depends on the scenario goal and the player count. In solo play or with 2 players this is a close to mandatory include for Jenny and Wendy, who both prefer to not habitually fight every last enemy that spawns on them. In larger groups, you stick together more, and more often you want to stay and, depending on your role, help fighting/tanking enemies, so your specialised buddies get freed up.

A small explanation of Think On Your Feet timing could be helpful for Lola players. Her innate free triggered ability may be triggered as a player ability during any player window. The first player window during the Mythos Phase would be after Step 1.4 Each investigator draws 1 encounter card. Since the triggering condition on Think On Your Feet begins with the word "when...", it may be used after the specified triggering condition (an enemy is about to spawn) initiates, but before its impact upon the game state resolves. In other words: there is typically no opportunity to switch roles while you are drawing encounter cards from the encounter deck, so she’d have to switch to Rogue sometime before the Mythos phase in order to play Think On Your Feet. But whenever there is a skill test, (e.g. if by chance another player draws a treachery card before Lola,) Player Windows open up before and after cards are committed to the skill test (as depicted on RR page 26). So Lola could switch to Rogue during that time.

Pros

• Great click-compression. Gain two actions for the cost of none!
• Fast cards aren't subject to Attacks of Opportunity, so in case you are engaged (by another enemy) when playing this card, that (non-Massive) enemy stays in your threat zone and moves with you, but does not attack out of opportunity.
• Guaranteed result. This card is very likely to be used during a scenario, you can also flee from Weakness enemies like Mob Enforcer with it.
• Works on Elite spawns, also!
• In hard/expert difficulty the speed gain adds greatly to this event's value.

Cons

• Befits not in every situation. If you want or have to fight for some reason, the event is to no end.
• The enemy does not count as defeated for combo purposes.
• Only helps the investigator who plays it.

Recommendations

• spoiler Flee from unpleasant roamers in Undimensioned and Unseen.
• spoiler Greatly speed up convincing a zealot in The Gathering.
• It is not so useful in The Devourer Below and in The Essex County Express.

The basic version of Emergency Cache is included in a majority of decks. There must be a reason why the upgrade has to be searched with magnifying glasses, it is rarely included by Arkhamdb players.

Considerations about the value of this card are found under the basic version of Emergency Cache(0).

The cost of 2xp have to be put into relation to the additional effect that the upgraded version gives you.

Which is... "Draw 1 card." I still do not think that this effect is worth the additional 1xp. I just wonder about people who include Lucky!(2) during the course of a campaign but not Emergency Cache(2). Or why it is not found more frequently in Roland Banks decks. This investigator is so beggarly, he can use a cash injection at any time during a scenario and would be thankful for the extra card!

For Roland, Emergency Cache(2) has the same power level as Police Badge(2) or even Beat Cop(2).

Pros

• Saves one action, you gain another card.

Cons

• There is a small danger of drawing a Weakness from your deck which could meddle with your plans.
