Piège Rudimentaire


(from the official FAQ or responses to the official rules question form)

Q: If Parallel Ashcan Pete owns a copy of Makeshift Trap with Explosive Device, and he chooses to trigger his reaction ability when the card would be discarded, does the Explosive Device damage still happen? A: Parallel Ashcan Pete’s reaction ability triggers when an attached card “would be discarded,” which has a higher timing priority than “is discarded,” and replaces the discarding of that card. As such, Parallel Pete adding Makeshift Trap to his hand would make it so the Explosive Device upgrade does not trigger. (Rules Q&A, August 2023)

I am working on a Patrice Hathaway deck right now that uses the new difficulty 0 archetypes, and I am considering this card. I couldn't really make myself an opinion after 5 minutes of checking every option, so I thought I'd go for a deeper analysis of the possibilities offered by this card and share it here so that others can benefit from it too.

The Effect:

Enemies at your location are easier to evade/fight. This costs an action and therefore provokes attacks on opportunities.

The only way to make this card playable is then to plan on having an enemy at your location next turn. There are many ways to do so, including: Gloria Goldberg and her encounter deck manipulation, Parallel Fates, On the Hunt, Kicking the Hornet's Nest, Nine of Rods, First Watch, Scroll of Secrets, especially the one and we can go as far as mentioning Predator or Prey and hunter enemies.

The -1 difficulty makes it a good candidate for the difficulty 0 archetype. It synergises well with Impromptu Barrier and Flashlight (3) to bring down evasion tests to 0 and use Exploit Weakness.

Overall, as with some other customizable, this is an underpowered effect, and I doubt anyone will play this 0xp.

The Upgrades

  • □ Improved Timer:

    • Increasing the timer increases the chance to play it on a location and see it used before it is discarded. It is interesting in combination with Net to gather more enemies at the same location and with Poisonous to deal more damage to enemies trapped.
    • Decreasing the time, on the other hand, only synergises with Explosive Device.
  • □ Tripwire:

    • Do not waste it anymore. This is super useful for making a landmine with Improved Timer and Explosive Device. Formidable against hunter enemies.
  • □□ Simple:

    • Let's face it, Makeshift Trap actually costs 1xp since you will always want Simple. means no Attack of Opportunity while playing it, allowing you to keep it in hand and play it defensively.
  • □□ Poisonous:

    • Adds DOT (Damage On Time) to your trap. It is half the experience of Explosive Device, doesn't attack allies but is much slower and does not have the AOE (damage to every enemy at the location).
    • This will mostly see use in evading investigators as the damage is given after the Enemy Phase, and so you will not kill any enemy before you are attacked.
    • To compare it: if it is Simple and Poisonous, you are paying 4xp to have a 1-cost Cheap Shot that wouldn't add your but just give +1 instead. That is quite bad...
  • □□ Remote Configuration:

    • Attaching it to a revealed location doesn't bring anything by itself since you are usually evading/fighting enemies at your location. A few exceptions exist, like Marksmanship, Telescopic Sight, Springfield M1903, Onyx Pentacle and probably others, but I don't see this combo being used in any of these situations.
  • □□□ Net:

    • If you have Simple, you can now play your trap and just move location, leaving any enemy behind. This also deals with hunter enemies.
    • Add Poisonous and Improved Timer to deal with a 3-health enemy without spending an action other than the normal move.
    • That makes the evade and fight bonus a little bit irrelevant as you can now just ignore enemies completely.
  • □□□□ Explosive Device:

    • The flashy upgrade looks like Dynamite Blast but takes a lot of xp. The main disadvantage is that it explodes at the end of the round, so after the enemy phase.

The synergies:

  • The Dynamite Blast: Remote Configuration + Explosive Device_ + Improved Timer = 7xp

    • Pros: 1 resource instead of 5, have less ways to deal great amount of damage than .
    • Cons: Dynamite Blast is great for 0xp, but 3.5xp for the same effect, even cheaper, is too much to be worth it. If you add Simple, you get Dynamite Blast (3), which is not a great card and still costs +1.5xp per copy, and it doesn't explode before the enemy phase.
  • The Land Mine: Explosive Device + Improved Timer + Tripwire = 6xp

    • Pros: it's fun to drop a 3-damage mine at one location. It becomes increasingly interesting if you know the scenario and can plan in advance where some enemies will spawn. It is great to deal with a hunter enemy while you need to move. Add Simple, and it works amazingly with Track Shoes, as you can drop it during the test triggered by the shoes. This last use is probably my favourite of them all.
    • Cons: It is a rather big amount of experience.
  • The Net: Simple + Net + Improved Timer = 5xp

    • Pros: Cheap and reactive way to protect yourself against enemies. It gives time to your enemy manager to potentially come and finish the job.
    • Doesn't work on Elite enemies, so you'll need another way to deal with them.
  • The Remote Net: Net + Remote Configuration = 5xp

    • Pros: Block hunter enemies. Protect a cluever from AoO and gives them time to move out.
    • Con: Quite situational, and the customizable mechanic prevents you from only getting 1 copy.
  • The Poisonous Net: Net + Simple + Poisonous + Improved Timer = 8xp

    • Pros: Deal with a 3-hp non-elite enemy , test less and for 1 resource. It can also trap other enemies. It helps your enemy manager with finishing the enemies trapped.
    • Cons: It's a lot of experience for this.
  • The versatile bomb: Simple + Remote Configuration + Explosive Device_ + Improved Timer + Tripwire = 10xp

    • Pros: This trap can be both a land mine and a remote bomb. As often run out of upgrades, that is a fun way to spend your extra experience points while creating more opportunities for yourself.
    • Cons: Obviously, 10xp is a big ask for something that will not win you the game nearly as much as other 5xp cards will.

Who's that for?

So, now that we've seen some of the uses we can make out of this, the question becomes: who'd be interested?

  • Rita Young will like a Simple and Explosive Device trap as she can evade and leave the enemy behind or add an additional damage. Disguise also helps with leaving a hunter enemy in a Poisonous trap for a little longer. She can also spice it up with cards Bait and Switch (3) to bundle enemies.

  • Any investigator planning on using Flashlight (3) and Impromptu Barrier to use Exploit Weakness will appreciate a Simple trap. Patrice Hathaway will add Tripwire and just drop a trap as she'd drop an Open Gate when it arrives in her hand.

  • Any high that has the Track Shoes and is happy to drop a Land Mine and run away.

  • Patrice Hathaway can use Power Word to move enemies to the trap before it explodes and leave a Summoned Servitor at the location of a trap to evade the enemy and make sure that it stays until the grand finale.

  • Calvin Wright as a way to do a kamikaze device dealing 3 damage to himself as well as killing enemies in the process.

  • Minh Thi Phan and Preston Fairmont could have liked a Simple Net, but they cannot spend 5xp on it... There do not seem to be any 4xp combination that is worth considering for them or any other non-main .


I think it's a bit of a miss with this customizable card. It could have a spot in the Difficulty 0 deck, but it takes a bit of XP to start being worth it, and the better upgrades hardly see any play at all. There are so many good cards nowadays that it's hard to justify a spot for the trap as is, but there is definitely a couple of investigators that could use it.

I wish the non-elite close were limited to Net and that Net did not prevent AoO while being 1 or 2xp instead of 3, making it usable for 0-2 access.

Great review! I agree this is a tough card to slot in since it seems to take some XP just to get it on par with existing level 0 effects. — housh · 164
3 box upgrades can be used by 0-2 access investigators. A customizable card's level is half it's checked boxes (rounded up), so 0-2 access investigators can put up to 4xp into those customizable cards. — Death by Chocolate · 1394
His point is that Makeshift Trap is not very playable without Simple, leaving at most 2 lackluster upgrade boxes for you. On the other hand, if there is a location Minh and Preston knows they'll be at for a while (the quintessential 4 shroud, 2i clues, Victory 1 location for example), Improved Timer/Tripwire plus Net is a nice insurance to make sure they can still do stuff while waiting for the fighter to come rescue them. Not sure if it's worth the investment though. — koaexe · 27

Crazy good in Innsmouth, especially in Horror in High Gear with Net. Enemies get stuck at a location for so long you have time to get to Falcon Point. One of the main ways the Encounter deck makes the scenario hard is by triggering Hunter abilities during the Mythos. When they're trapped in a net, they still don't move. Thus, even the Encounter deck is mitigated by this card.

Luke/Barricade also breaks the scenario. — MrGoldbee · 1419

I would like to add a new perspective to □ Tripwire. Players might think of a time bomb trip wire with 1 count by combining with □ Improved Timer and □□□□ Explosive Device (additional 5 XP investment). But you can stop at just □ Tripwire. By eliminating any enemy appearing in the same turn they appear utilizing -1 Fight, -1 Evade, the trap lasts indefinitely! If you want to put minimal XP in the trap this is a strong 1 XP wonder.

My friend was attempting to left □□□□ Explosive Device around with some timer and Resign, leaving the rest of the team to lure enemies to the bomb and fight using the reduced fight and evade. It was a cool but unfortunately the rule says the trap must be removed following that player's elimination (resign). (Same for attached Map the Area, Breach the Door, etc.)

Control of Attachments : Player retain control of the card attached to location (which is a scenario/encounter card).

Elimination : The cards he or she controls in play and all of the cards in his or her out-of-play areas (such as hand, deck, discard pile) are removed from the game. Any card that player owns but does not control that is in play remains in play, but if that card leaves play it is removed from the game. (The trap is both owned and in control, so it will not get remain in play.)

Makeshift Trap is amazing card. Sometimes, the game may break due to the single Makeshift Trap. In this review, the upgrades are considered: Improved Timer, Simple, Net. Thus, Makeshift Trap has the following ability:

Uses (3 time). Fast. play during any window. If Makeshift Trap has no time, discard it.

Attach to your location.

Each non-Elite enemy at attached location get -1 fight and -1 evade.

Non-Elite enemies at attached location cannot move or make attacks of opportunity.

Forced - At the end of the round: Remove 1 time from Makeshift Trap.

It's noted that...

  • After the enemy is spawned (and thus engages), Makeshift Trap can be played without AoO.
  • All investigators at that location can move out without AoO. Enemies still stay at that location (including each enemy engaged with the investigators) since they cannot move.
  • The enemy can attack by the default attack during enemy phase. The investigator just moves out of the location to avoid being attacked.
  • Then, the enemy is locked at that location for three rounds. If the location is placed as line segment, Makeshift Trap works as Barricade.

From my interpretation of "cannot move" it means the enemy cannot voluntairily move. But it can BE moved by an investigator. My point of reference is [Formless Spawn](/card/04337), which specifically states that it cannot move and cannot BE moved. Meaning, an enemy trapped in a [Makeshift Trap](/card/09100) cannot move but CAN be moved. — MaleficMarby · 31
I think there is no difference between moving and being moved, similar as engagement. It's too hard to classify whether the enemy moves or is moved. — elkeinkrad · 473
Moreover, the given case is not the enemy is moved but enemy moves according to RR. It states "Each enemy in an investigator's threat area is considered to be at the same location as that investigator, and should the investigator move, the enemy remains engaged and moves to the new location simultaneously with the investigator". — elkeinkrad · 473

The introduction of Survival Technique in the Hemlock Vale set creates new possibilities for all our old favorite traps, especially this customizable beauty. Survival Technique allows you to return one of your cards attached to a location to you hand each turn, which means that you can relocate these traps and keep them going indefinitely. You will definitely want Simple so you don't want actions re-setting them, and may also want the tripwire or improved timer to cut down on the resource cost of frequent replays, although honestly you will probably move around enough that you rarely need to reset one without moving it anyway.

That 1 cost to redeploy could become negligible anyway if you're running Dark Horse or Madame Labranche or On Your Own or The Fool • 0.

If you manage to find both you can even stack them to give all non-elites a -2 difficulty, and if you make them poisonous you can even deal some damage over time to the elites so the guardian can't say you didn't help at all.

At one point there were FAQ answers floating around implying that Survival Technique would boost basic investigates, which I thought might make it enough of a staple to reshape the playing field. As things stand, the difficulty of finding and playing a 2xp talent and then both copies of your ~level 2 trap is significant enough (none of them have easily tutored for traits) that the juice probably isn't worth the squeeze unless you have a lot of other pieces that interact with it.
