Damage resistance¶
Resistance to a damage type halves damage of that type against you, rounding down. Multiple sources of the same Resistance do not stack. Resistance does not normally alter the attack roll or saving throw.
Order of damage adjustments¶
Apply other damage adjustments first, then Resistance, then Vulnerability. Resolve different damage types separately. For example: 28 Fire damage, reduced by 5, becomes 23; Fire Resistance halves that to 11; Fire Vulnerability doubles that to 22. Resistance and Vulnerability therefore do not always cancel exactly because of rounding.
Immunity and Vulnerability¶
Immunity to a damage type means you take none of that damage. Immunity to a condition prevents that condition, not all damage associated with its source. Vulnerability doubles damage of its type and applies only once per instance. Resistance to Poison damage and immunity to the Poisoned condition are distinct benefits.
Finding your resistances¶
Check species traits, active class/subclass features, spells, equipped and attuned items, and their conditions. A resistance can be permanent, temporary, or conditional; equipping an item alone does not establish that every activation requirement is met.
