Natural 1 Table — Dexterity Saves and Checks, d100

A free d100 table for a natural 1 on a Dexterity 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 Dexterity specifically. A blown Dexterity roll should fail in a way that has something to do with Dexterity — 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

d100	Result	Tier	What happens
1	Caught Flat-Footed	Slip	No mechanical effect. You simply didn't move in time, and you know it.
2	Scuffed Landing	Slip	You come down harder than you meant to. Cosmetic.
3	Clattered Something	Slip	Anything within 30 feet that can hear knows someone is moving around here.
4	Fumbled It	Slip	One light item you were handling falls into your space.
5	Twisted Wrong	Slip	A joint complains. No mechanical effect.

81	Ally Hurt Badly	Ruin	An ally within 5 feet takes 2d6 damage in the collision, the fall, or the collapse.
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 Hurt	Ruin	You take 2d6 damage and have disadvantage on attack rolls until you regain any hit points.

93	Made It Impossible	Ruin	This approach can't be attempted again this scene. The party needs another way.
94	Ally Trapped	Ruin	An ally within 5 feet is pinned 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	You go through, into, or under something that was holding the room together. 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, down the grating. Recovering it is a side quest, not an action. A magical item is always recoverable eventually.
98	Hurt the One You Meant to Help	Infamy	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.
100	The One They'll Tell Stories About	Infamy	You end up prone, empty-handed, tangled in the scenery, and perfectly framed for everyone watching. 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.
