Sometimes, despite our best efforts, we don't always win. But not all failures are equal—sometimes we mess up a little, sometimes we mess up catastrophically. Sometimes, we even have a chance to prevent failure—at a small, extra cost.

This chapter introduces degrees of success, allowing you to judge the scale of success and failure accordingly.

Success & Failure

When you attempt an action that has a chance of failure, compare your result to the DC and check the list below to see just how well you did.

  • Critical Success: You succeeded by 10 or more on a skill check, or rolled a natural 20 on an attack. Things have gone perfectly. You achieve your goal and something else happens in your favor.
  • Success: You achieve your goal.
  • Minor Failure or Success at a Cost: You failed by 1, 2, or 3. You can choose to succeed, but something bad also happens as a consequence.
  • Failure: You failed by 4 or more. Something bad happens—you take damage, gain Stress, lose a hit die, a Condition worsens, etc.
  • Critical Failure: You failed by 10 or more on a skill check, or rolled a natural 1 on an attack. It's all gone badly for you and you suffer a second consequence in addition to the normal failure effects—you take extra damage, lose a hit die, drop an item, etc.

Krazak is critically hit by an enemy. He takes damage for failing to dodge, then additional damage (the crit damage) for critically failing—two consequences.


When a character succeeds with an ability check or attack roll, something good happens and they get what they wanted. The type of this reward is often clear from the context of the character's action—you hit the monster, you unlock the chest, you identify the potion, etc.

But if the reward isn't clear—or you want to give a character an extra boon for a critical success—consider some of the examples below.


d20 Boon
1 You restore some hit points
2 You gain a hit die
3 You find some extra gold
4 You gain a favor from an ally
5 You regain a spell slot
6 You deal extra damage
7 You heal some mental stress
8 You may spend a hit die to recover some hit points
9 You may switch places with a nearby ally
10 You can move to an advantageous position
11 You learn a piece of rare information
12 You (temporarily) lose one level of exhaustion
13 A magic item regains one charge
14 The locals hear about your achievement
15 You apply a condition to your enemy
16 A god notices your achievement
17 A condition improves
18 You gain advantage to your next roll
19 Your enemies are intimidated by you
20 You move your enemy


When a character fails an action, something bad happens. The type of this consequence is often clear from the context of the character's action—you take damage from an attack, you anger the guards, you fall into the pit, etc.

But if the consequence isn't clear—or you want to give a character an extra consequence for a critical failure—consider some of the examples below.


d20 Consequence
1 You or an ally take damage
2 An enemy reacts and takes an action
3 You gain some mental stress
4 Take a notch on your weapon/armor/item
5 You lose an item
6 One of your conditions worsens
7 Your torch goes out
8 An NPC becomes hostile to you
9 You lose some gold
10 You learn some misinformation
11 Your enemy becomes enraged
12 You gain the attention of the local guards
13 You drop your weapon
14 You stop and fall prone
15 You are poisoned or diseased
16 You are imprisoned
17 A crowd turns against you
18 A higher authority learns of your misdoings
19 A god punishes you
20 You lose some ammunition or hit dice

Success at a Cost

When you fail by a narrow margin, you may choose to succeed at a cost instead—you get what you want, but something bad happens to you as a consequence.

This may require some negotiation with the GM—if you can't both agree on the cost, you can't succeed. Check the Offerings table below for some inspiration.


d10 Offering
1 25% or 50% of your total hit points
2 You lose one or more hit dice
3 You lose one or more spell slots
4 An item gains a notch
5 You gain a condition
6 You gain the attention of the enemy
7 You are moved into a disadvantageous position
8 You lose an item
9 You gain a level of exhaustion
10 You lose some gold
11 An NPC is put in a perilous situation
12 You lose renown with a person or faction

Examples of Play

Here are two examples of how to use degrees of success in your game—one to demonstrate Success at a Cost and a negotiation, and another to show critical failure in action.

Chansi is trapped on a collapsing ledge over a dark abyss. Luckily, her friends have thrown down a rope for her to climb to safety.

  • GM:The ground is crumbling rapidly beneath your feet, Chansi—but you see a rope hanging ahead, over the dark abyss.
  • Chansi:I leap out and grab hold of it.
  • GM:Ok, that's a DC 15 Strength check.
  • Chansi:I should be able to use Athletics for this, so that's... (rolls 14) ...augh, so close!
  • GM:Very close indeed, the rope barely slips past your fingers. You have a chance to succeed at a cost...
  • Chansi:Damn, I can't fall into the abyss. Perhaps... something falls out of my bag as I grab hold? Those old mushrooms I picked up earlier maybe?
  • GM:It has to be something precious to you.
  • Chansi:Ah. Well I was really hoping to use this healing potion later...
  • GM:Perfect. For a moment you fall, barely catching the rope at the last second with your other hand. But as you hang, you hear a small rip from your bag and your healing potion tumbles into the abyss below.
  • Chansi:Augh, I really needed that potion...

Viridan, meanwhile, has bluffed his way into a meeting with a local lord—Erasius, Lord of Brekenwell. Viridian hopes to convince the lord to lend his support in the defence of a nearby village.

  • GM:Lord Erasius looks at you coldly, Viridian—he doesn't seem impressed. "And why should I trust you, stranger?"
  • Viridian:Hmm, good question. Can I lie, saying that I'm nobility with access to the king? I'll tell Erasius that—if he will support us—I can put in a few words to boost his reputation with the king.
  • GM:Ok, that sounds like a tricky lie to me. You haven't had time to prepare this, and you don't have any items to back your claim, so it's an off-the-cuff bluff—make a DC 25 Charisma check.
  • Viridian:Can I use History with this?
  • GM:Yes, you know enough about the local lands to throw around a few names.
  • Viridian:Great. That's... (rolls 13) ...eep, not good.
  • GM:No, it isn't—it's a critical failure. Erasius can see right through your lies, and—as a second consequence—he's extremely offended. "You come into my home and dare lie right to my face? Perhaps some time in our dungeons will extract the truth from you. Guards!"
  • Viridian:Son of a...
