Improvised Damage

HazardDMGp. 2492014

In some cases you need to determine damage on the fly. The Improvising Damage table gives you suggestions for when you do so.

Improvising Damage

DiceExamples
1d10Burned by coals, hit by a falling bookcase, pricked by a poison needle
2d10Being struck by lightning, stumbling into a fire pit
4d10Hit by falling rubble in a collapsing tunnel, stumbling into a vat of acid
10d10Crushed by compacting walls, hit by whirling steel blades, wading through a lava stream
18d10Being submerged in lava, being hit by a crashing flying fortress
24d10Tumbling into a vortex of fire on the Elemental Plane of Fire, being crushed in the jaws of a godlike creature or a moon-sized monster

The Damage Severity and Level table is a guide to how deadly these damage numbers are for characters of various levels. Cross-reference a character's level with the damage being dealt to gauge the severity of the damage.

Damage Severity and Level

Damage sufficient to cause a setback rarely poses a risk of death to characters of the level shown, but a severely weakened character might be laid low by this damage.

In contrast, dangerous damage values pose a significant threat to weaker characters and could potentially kill a character of the level shown if that character is missing many hit points.

As the name suggests, deadly damage is enough to drop a character of the level shown to 0 hit points. This level of damage can kill even powerful characters outright if they are already wounded.
