Natural 1 Table — Wisdom Saves and Checks, d100

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

87	Startled It	Ruin	Whatever you were tracking, treating, or calming reacts violently. Every creature within 5 feet must succeed on a DC 13 Dexterity saving throw or take 2d6 damage.
88	Attracted Attention	Ruin	A wandering monster or reinforcement of the DM's choice arrives in 1d4 rounds.

96	Set It Off	Infamy	Whatever you disturbed reacts all at once, and takes part of the room with it. The DM introduces a hazard or a countdown. You take 2d6 damage and fall prone.
97	Gone Entirely	Infamy	Your kit, tools, or holy symbol leaves the scene entirely. Recovering it is a side quest, not an action. A magical one is always recoverable eventually.
98	Hurt the One You Meant to Help	Infamy	Your treatment, your warning, or your reassurance does the opposite. The ally nearest to you takes 4d6 damage, or half as much on a successful DC 13 Dexterity saving throw.
99	Out Cold	Infamy	It's simply too much. You're 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	Your nerve, your judgement, and your footing all go at once, in front of everybody. 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.
