It’s a Trap! To Roll or Not To Roll?

I just read that on r/osr and it made me think.

How to deactivate or avoid a trap without making a roll? Is it possible? Of course it is, let’s look at some examples:

Referee: To one side of the road there are bushes with wild berries. They look delicious.
Player A: I approach and start collecting blackberries.
Referee: A snake bites you. You are dead.
Player A: Oh, come on!
Player B: With a ten foot pole I examine the bushes for any dangers.
Referee: When lifting the pole, a snake has curled into it.
Player B: I throw the pole like a javelin and collect berries.

Referee: There’s some haze but you can see the bridge well.
Player A: I advance to the other side.
Referee: You fall and die.
Player A: What?
Player B: I advance slowly so as not to slip.
Referee: You get to the other side without problems.

Referee: In front of you there is a door.
Player A: I open it.
Referee: You activate a trap. You feel the needle, but you are dead before your body hits the ground.
Player A: Fuck you!
Player B: I look at the lock for traps.
Referee: You don’t see anything.
Player B: I use my lockpicks to try to disarm the trap, if there is one.
Referee: You trigger the trap. You are dead.
Player B: Why? It’s not fair!
Referee: Okay, you disarmed it.
Player A: It’s not fair! You killed me, and you let him live!?

There it is. Traps without throwing dice. Lovely, ennit?

In the first two cases, success is automatic if players take some precautions, but then failure is also automatic if they do not. Is it unfair? No. No, it’s not. It’s not unfair but it might seem so and people’s feelings might get hurt. Adjudication made sense in both cases, but from the players’ perspective, it can seem arbitrary.

In the third case it’s more difficult to adjudicate success or failure by just following the fiction, since suspecting that there is a trap and trying to deactivate it, is no guarantee that it will be deactivated. Both success and failure feel arbitrary, unfair, and even like cheating. A referee’s job should be easier.

That’s why baby jesus invented dice rolls

When players fail after making a dice roll, they won’t (usually) blame the referee or believe that their failure is an injustice, but a product of chance—although in reality it is not (only) chance: A failure isn’t the fault of a bad roll but of a bad decision. You can always choose not to cross the bridge, not to collect berries, not to open the door, doing something else instead, and return later, when you have made preparations, purchased potions, or whatever.

If we follow the rules of the game (as we are supposed to), Mr. Player A will have the opportunity to make a Save versus Poison to avoid dying from the snake bite, and a Save versus Paralysis to avoid falling into the abyss. And both players will have the opportunity to disarm the lock trap with a successful Tinkering roll (or equivalent), and to avoid damage if this roll is failed, making a Save versus Poison; they could even have a bonus to the first roll if they have tools (such as Player B).

Last words

Sometimes you really have to throw dice to discover or disarm a trap (like the proverbial poisonous needle in a door lock), and to avoid damage (or dying) if the first roll was failed.

Other times the trap is evident (such as the slippery bridge) and it only requires one roll to avoid its effect, and success can be automatic (at the referee’s discretion) if appropriate measures are taken (such as walking slowly, wearing mountaineering boots, &c).

Finally, at times the trap is discovered and deactivated by performing a specific action (such as the snake between the bushes with a pole), and would only require a roll to avoid the effect if activated.

A little advertising

Get a good book of traps! It’s a collection of a bunch books written by Steve Crompton and others, published by Flying Buffalo back in the 80s and 90s, reprinted here by Goodman Games. The first is also an affiliated link, so I might earn a few silver coins if many of you buy the PDF (which I will use to buy more RPG books).

Old-School Saving Throws Are Rad!

Old-School saving throws tell you against what you are defending; the “how” is left to your imagination.

Like everything in these games, saving throws are a mechanism and not a narrative; the player rolls the dice and the player or referee interprets the result (success or failure) according to the context, or he can ignore the interpretation and it doesn’t matter, the game moves on.

For example, an attack roll doesn’t represent the same in all cases; if successful, it can represent different forms of attack and defense made in a round: thrust, feint, riposte, swing, parry … The important thing is that the dice tell you if you succeed or not, whereas the form of the attack (the “how”) is irrelevant. It’s up to the players to describe it or ignore it and move on with the adventure.

The same applies to saving throws.

While, since 3e, the saving throws tell you the “how” (a reflex save meaning that the character throws himself aside to dodge an attack, a fortitude save meaning the character receives the attack but resists it as would a boxer being punched, a willpower save meaning … well, who knows what the hell it means, that your soul is hard as steel, perhaps?*), old-school saving throws are a mechanic to represent what you are defending against and what are your chances of success, leaving you the responsibility to describe the way your character does it (a responsibility, however, completely negligible).

Thus, we have the 5 categories of old school saving rolls, specifically Basic/Expert Sets (B/X, BECMI), and most OSR retrcolcones, like Labyrinth Lord and Old-School Essentials:

  • Death Ray or Posion
  • Magic Wands
  • Paralysis or Turn to Stone
  • Dragon Breath
  • Rods, Staves or Spells

And these are the categories of AD&D 1e:

  • Paralyzation, Poison or Death Magic
  • Petrification or Polymorph
  • Rod, Staff or Wand
  • Breath Weapon
  • Spell

And, just for fun, those of LotFP:

  • Paralyzation
  • Poison
  • Breath Weapon
  • Magical Device
  • Magic

Although the categories vary from one version to another, the mechanics are identical: you make a saving throw when you are in imminent danger. In normal combat, if an enemy attacks you with his sword, your AC protects you, which not only represents your armor, but also your ability to defend in combat.

But in the face of other dangers, such as a dragon that throws you fire, a basilisk that looks you in the eye, ingesting poison or being the target of a spell (or magic wand), your AC (defense capability plus armor, remember?) does not come into play, but you still have a chance, even if it is small, to avoid damage.

Save Versus Something

Save versus Poison. The adventurer probably did nothing to avoid dying poisoned, the roll is passively successful, the reason he didn’t die can be anything from the poison having no effect or the creature failing to inject it to the adventurer being immune to this specific poison, even divine intervention, or maybe those luminous mushroomes he ate that morning neutralized all toxins.

In 3e, this saving throw would be a fortitude save, and in 5e, a constitution save (which come to be the same, actually). This can only be interpreted in one way: the poison didn’t kill the adventurer due to a powerful immune system.

Of course, the old-school allows this same interpretation, but not only this; it gives you the freedom to interpret the numbers as you see fit.**

Save versus Spells. A damn magic-user attacks you with a fireball. To avoid damage (or, well, half the damage), in 3e or 5e you must make a reflex or dexterity save, meaning that you dodge the fireball (the spell’s description makes this interpretation unlikely, though), but in the old-school we really don’t know how you do it other thank making a save versus Spells (i.e. we only know the mechanic, but we are not offered a narrative interpretation***); maybe the agile thief jumps to the side, yes, but think about that heavy fighter with full armor, can he really dodge? Most likely his armor protects him, but if the idea of a hot metal armor not causing severe damage bothers you, then you can say that he used his sword to deflect the explosion, or he punched the ball of fire like those Dragon Ball fighters do all the time.

Now imagine that you are on a cliff, there is no space to dodge without falling from a great height (and no doubt die), but anyway you make a successful saving throw. Did you dodge the attack? I don’t think so. In the case of a magic-user or an elf, it’s easy to imagine that they know a mystical handsign that works to counter or deflect a spell, reducing (or denying when appropriate) its effectiveness.

The thief and halfling are lucky and that strange, outer, chaotic force known as luck interferes with the spell, reducing its effectiveness. A cleric is protected by his faith (which is another form of magic, or anti-magic if you consider magic as something unholy). The fighter, like the dwarf, relies more on his instinct, his strength, his ability, and in general “sheer defiance”, all of these tangible or demonstrable things, not abstract, philosophical things like magic, and that confidence makes them face magic with disdain, reducing its effectiveness.


* It doesn’t matter, the game moves on.

** Of course you can interpret 3e and 5e saves in any way you see fit.

*** To be honest, 1e offers both a narrative option (“Defensive Adjustment refers to the penalty or bonus applicable to a character’s saving throws against certain forms of attack [such as fire ball, lightning bolts, etc.] due to dodging ability.” PHB, p. 11) and the old-school option (“If some further rationale is needed to explain saving throws versus magic, here is one way of looking at it … A character under magical attack is in a stress situation, and his or her own will force reacts instinctively to protect the character by slightly altering the effects of the magical assault … So a character manages to avoid the full blast of the fireball, or averts his or her gaze from the basilisk or medusa, or the poisonous stinger of the giant scorpion misses or fails somehow to inject its venom. Whatever the rationale, the character is saved to go on.” DMG, p. 81)
