Natural 20 Table — Survival Skill Checks, d20

A free d20 table for a natural 20 on a Survival check in 5e. Twenty outcomes, from solid to legendary.

A natural 20 on a skill check is not a critical success in fifth edition — criticals apply to attack rolls only, and a 20 on a check is simply a 20. Which is why a legendary roll so often feels like nothing happened. This table gives it somewhere to land.

Twenty results written for Survival specifically. A legendary Survival roll has nothing in common with a legendary roll at anything else, which is why there are eighteen of these and not one.

Roll d20 when a player rolls a natural 20 on a skill check and succeeding quietly would be a waste.

Severity tiers

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

Solid 1–10 — Cleanly done, with something small to show for it.
Impressive 11–17 — Better than anyone expected. Momentum, or an obstacle gone.
Legendary 18–20 — Scene-shaping. The kind of success people repeat afterwards.

The table

20 results. Roll d20.

d20	Result	Tier	What happens
1	Clear Trail	Solid	You follow it without hesitation. No extra effect.
2	How Many	Solid	You determine the number, size, and direction of what you're tracking.
3	How Long Ago	Solid	You know exactly how far ahead they are, and whether you can catch them.
4	Good Camp	Solid	You find shelter that is genuinely safe. The party rests undisturbed.
5	Fed Everyone	Solid	You provide food and water for the whole party for the day.
6	Covered Your Own	Solid	You hide the party's tracks as you go. Nobody is following you.
7	In Your Element	Solid	You have advantage on your next Survival check this scene.
8	Read the Sky	Solid	You know what the weather will do for the next day and can plan around it.
9	Showed the Party	Solid	Every ally has advantage on their next Survival check in this terrain.
10	One Was Injured	Solid	You learn something specific about what you're following — a wound, a limp, a burden.
11	Shortcut	Impressive	You find a route that cuts the journey substantially, or gets ahead of what you're chasing.
12	Where They're Going	Impressive	You work out the destination without needing to follow the whole trail.
13	Set an Ambush	Impressive	You can position the party to intercept. The DM grants surprise if the encounter happens here.
14	Through the Hazard	Impressive	You bring the party through dangerous terrain with no checks and no cost.
15	The Old Path	Impressive	You find a route nobody has used in years — and it goes somewhere useful.
16	Provisioned	Impressive	You gather enough that the party doesn't need to forage again for a week.
17	Never Lost It	Impressive	You cannot lose this trail. Rain, stone, water, or misdirection — you keep it for the rest of the pursuit.
18	Found What Was Lost	Legendary	You track something the party had given up on entirely — a person, a caravan, a place off every map.
19	The Land Reads Back	Legendary	You reconstruct everything that happened along this route: who came, what they did, and what they were running from.
20	The One They'll Talk About	Legendary	You bring the party somewhere nobody has reached in living memory, by a route that shouldn't exist. The journey chapter is over — you're there.

Questions

Is a natural 20 a critical success on a skill check?

Not by the rules. Criticals apply to attack rolls. A 20 on a check is a 20 — which is why a spectacular roll so often produces a shrug. This table is the house rule that fixes that.

Does a natural 20 automatically succeed?

No. On an ability check there is no automatic success — if the DC is 25 and your total is 22, you failed with a 20.
