Natural 1 Table — Strength Saves and Checks, d100

A free d100 table for a natural 1 on a Strength save or check in 5e. 100 outcomes, graded by severity.

Fifth edition does not critically fail saving throws or ability checks either: a natural 1 is just a 1, and on a check it can still succeed if the modifier is high enough. This table is for DMs who want the genuinely bad roll to land as something, and it is graded so that most results cost very little.

Written for Strength specifically. A blown Strength roll should fail in a way that has something to do with Strength — which is why this is six tables and not one.

Roll d100 when a player rolls a natural 1 on a saving throw or ability check and you want the moment to land.

Severity tiers

Each result names its tier, so you can see at a glance how bad a roll was without decoding a colour.

Slip 1–20 — A moment's failure. It costs you nothing but composure.
Stumble 21–40 — A real but minor cost — tempo, position, or grip.
Lapse 41–60 — The attempt is gone, and so is your turn or your footing.
Debacle 61–80 — You are now measurably worse off than before you tried.
Ruin 81–95 — Real loss. Someone is going to remember this one.
Infamy 96–100 — Rare, spectacular, survivable. Describe it in loving detail.

The table

100 results. Roll d100.

d100	Result	Tier	What happens
1	Grunt of Effort	Slip	No mechanical effect. Everyone present heard exactly how hard you were trying.
2	Slipped Grip	Slip	Your hand skids and you catch it again immediately. No effect.
3	Popped Seam	Slip	A seam in your clothing gives out audibly. Entirely cosmetic.
4	Scraped Knuckles	Slip	No mechanical effect. It stings out of all proportion to the damage.
5	Boots Skid	Slip	You slide on loose ground and recover. Cosmetic.
6	No Leverage	Slip	No effect — you simply never had the angle for it, and now you know.
7	Red-Faced	Slip	No mechanical effect, but the strain is written all over you.
8	Cramp	Slip	No effect now. You shake it out and set yourself again.
9	Dropped Something Small	Slip	One light item you were carrying falls into your space.
10	Ringing Strain	Slip	Your ears sing with the effort. No mechanical effect.
11	Overcommitted	Slip	The first 5 feet you move on your next turn costs double.
12	Sweat in Your Eyes	Slip	You have disadvantage on your next Perception check.
13	Torn Glove	Slip	Your glove or bracer splits along the seam. Cosmetic.
14	Audible Strain	Slip	Anything within 30 feet that can hear knows someone is working hard here.
15	Pulled Muscle	Slip	You have disadvantage on your next Strength check.
16	Reset Your Stance	Slip	No effect. You take a breath and plant your feet properly this time.
17	Winded	Slip	You can't take a bonus action this turn if you haven't already used it.
18	Splinter	Slip	No mechanical effect, and it will bother you for the rest of the day.
19	Lost Your Place	Slip	Whatever you were bracing against settles back to where it started. No other effect.
20	Learned the Trick	Slip	The failure shows you where the leverage actually is. No penalty, and you have advantage on your next Strength check.
21	Slipped Backward	Stumble	You're moved 5 feet in a direction the DM chooses.
22	Grip Fails	Stumble	You drop whatever you were holding in one hand.
23	Wrenched Shoulder	Stumble	You have disadvantage on your next attack roll.

28	Jarred Loose	Stumble	A piece of your visible gear falls into your space.
29	Hand Numb	Stumble	You have disadvantage on your next attack roll made with that hand.
30	Gasping	Stumble	On your next turn you can move or take an action, not both. Bonus actions still work.
31	Braced Wrong	Stumble	You have disadvantage on Dexterity saving throws until the end of your next turn.
32	Into the Open	Stumble	You lurch out of position and lose the benefit of any cover until you move again.
33	Torn Strap	Stumble	Your pack sags badly. Spend 5 feet of movement righting it, or leave it behind.
34	Overexerted	Stumble	You take 1 damage.
35	Committed Too Far	Stumble	You can't move for the rest of this turn.
36	Loud Failure	Stumble	One nearby creature of the DM's choice comes to see what the noise was.
37	Blistered Hands	Stumble	You have disadvantage on the next check you make using tools.
38	Shook Something Loose	Stumble	A piece of the surroundings shifts. Cosmetic for now — the DM should make a note of it.
39	Fouled an Ally	Stumble	An ally within 5 feet is put off balance. Their next attack roll is made with disadvantage.
40	Down to One Knee	Stumble	You aren't prone, but you're low and awkward. Standing fully costs 5 feet of movement.
41	Flat on Your Back	Lapse	You fall prone.
42	Dropped Everything	Lapse	You drop everything you're holding into your space.
43	It Gets Away From You	Lapse	An object you were holding or moving lands 10 feet away.
44	Turn Spent	Lapse	The whole effort comes to nothing. Your turn ends immediately.

47	Legs Gone	Lapse	Your speed is 0 until the end of your next turn.

50	Pack Torn Open	Lapse	Your pack splits and one item spills into your space.

52	Shoulder Out of Line	Lapse	You have disadvantage on all attack rolls until the end of your next turn.
53	The Handhold Fails	Lapse	Whatever you were relying on — rope, ledge, harness — gives way. The DM decides where you end up.
54	Blinded by Sweat	Lapse	You're blinded until you use an object interaction to clear your eyes.
55	Cracked Something	Lapse	A non-magical item you carry is damaged, DM's choice. It still works, badly.

62	Deep Strain	Debacle	You take 1d6 damage.
63	Struck an Ally	Debacle	You lose control of the load or the limb. An ally within 5 feet takes 1d4 damage.
64	Shoulder Dislocated	Debacle	You have disadvantage on attack rolls with that arm until someone succeeds on a DC 13 Medicine check to set it.
65	It's Gone	Debacle	The object you were holding is flung 20 feet in a random direction.
66	Stunned by the Effort	Debacle	You're stunned until the end of your next turn.

69	Burst Vessel	Debacle	You take 1d4 damage and look genuinely unwell for the rest of the scene.
70	Made It Worse	Debacle	Whatever you were trying to move, open, or hold is now jammed harder. The DC to attempt it increases by 5 for everyone.
71	Item Broken	Debacle	A non-magical item you were using breaks. A magical one is merely bent and imposes disadvantage on its use until repaired over a short rest.
72	Pulled Into It	Debacle	You stumble into the nearest hazard or hostile creature's reach and provoke an opportunity attack from everything that can reach you.
73	Cracked Ribs	Debacle	You have disadvantage on Constitution saving throws until you finish a long rest.
74	Brought Others Down	Debacle	Every ally within 5 feet must succeed on a DC 12 Dexterity saving throw or fall prone.
75	Dropped Your Light	Debacle	Your torch, lantern, or other light source falls and goes out — or rolls 15 feet away if it can't be extinguished.
76	Winded and Down	Debacle	You fall prone, and your speed is 0 until the end of your next turn.
77	Spilled Pack	Debacle	One item from your inventory — DM's choice, never an attuned one — falls into your space and may be trampled.
78	Hands Useless	Debacle	You drop everything you're holding and can't pick anything up until the end of your next turn.
79	Something Gave Way Loudly	Debacle	The noise carries. A wandering creature of the DM's choice arrives in 1d4 rounds.
80	Betrayed by Your Own Strength	Debacle	You take 1d6 damage and fall prone.
81	Ally Hurt Badly	Ruin	An ally within 5 feet takes 2d6 damage as the weight, the swing, or the collapse catches them.
82	Item Destroyed	Ruin	A non-magical item you were using is destroyed outright. A magical one survives but is unusable until an hour's work restores it.
83	Badly Torn	Ruin	You take 2d6 damage and have disadvantage on attack rolls until you regain any hit points.
84	Thrown Clear	Ruin	You're hurled 15 feet, land prone, and take 1d6 bludgeoning damage.
85	Exhausted	Ruin	You gain one level of exhaustion.
86	Arm Broken	Ruin	You can't use that arm — or any two-handed equipment — until a lesser restoration or a long rest with proper care.
87	Structural Collapse	Ruin	Every creature within 5 feet, you included, must succeed on a DC 13 Dexterity saving throw or take 2d6 bludgeoning damage. A piece of cover is destroyed.
88	Attracted Attention	Ruin	A wandering monster or reinforcement of the DM's choice arrives in 1d4 rounds.
89	Let Something Go	Ruin	Anything you were holding, restraining, grappling, or bracing shut breaks free immediately.
90	Handed It Over	Ruin	The object you were struggling with ends up in a hostile creature's space, free for it to take.
91	Everything Falls	Ruin	You drop what you were holding, your pack, and one other item, each into a different space within 10 feet.
92	Wrenched Senseless	Ruin	You're stunned until the end of your next turn, and have disadvantage on Strength checks until you finish a long rest.
93	Made It Impossible	Ruin	Whatever you were attempting can't be attempted again by anyone this scene. The party needs another way.
94	Ally Trapped	Ruin	An ally within 5 feet is pinned by the collapse and restrained. Freeing them takes an action and a DC 13 Athletics check.
95	Out of the Fight	Ruin	You fall prone, drop everything, and your turn ends. You can't take reactions until the start of your next turn.
96	Brought It Down	Infamy	Whatever you were straining against gives all at once, and takes part of the room with it. The DM introduces a hazard or a countdown. You take 2d6 bludgeoning damage and fall prone.
97	Gone Entirely	Infamy	The object leaves the scene: over the edge, into the water, through the gap. Recovering it is a side quest, not an action. A magical item is always recoverable eventually — the DM decides how far you'll go.
98	Hurt the One You Meant to Help	Infamy	Your effort goes catastrophically wrong and the ally nearest to you takes 4d6 damage, or half as much on a successful DC 13 Dexterity saving throw.
99	Out Cold	Infamy	You knock yourself unconscious for 1 minute, or until you take damage or an ally uses an action to rouse you. You are not dying — you are simply, comprehensively spent.
100	The One They'll Tell Stories About	Infamy	You fail so completely that you end up prone, empty-handed, and tangled in whatever you were attempting, in full view of everyone. Every creature that can see you has advantage on attack rolls against you until the start of your next turn. You take no damage. Your dignity takes all of it.

Questions

Is a natural 1 an automatic failure on a check?

No. Automatic failure on a 1 applies to attack rolls and death saves. On an ability check or a saving throw, a natural 1 is just a 1 — add your modifier, and a skilled character can still succeed.

When should I roll on this?

Only when the failure matters. A natural 1 on a check nobody was watching is not a story.
