In Dungeons & Dragons 5th Edition (5e), damage resistance allows a character to take less damage from certain types of attacks. There are several ways to gain damage resistances, including wearing armor, casting spells, or using magic items.
Damage resistance is important because it can help characters survive longer in combat. By reducing the amount of damage they take, characters can stay in the fight longer and deal more damage to their enemies. Damage resistance can also be useful for protecting characters from specific types of damage, such as fire or poison.
