What is thorns in diablo 4?

In Diablo 4, thorns is a defensive attribute that reflects a percentage of damage taken back to the attacker. Thorns damage is a passive effect that triggers whenever the player is hit by a melee attack. The amount of damage reflected back to the attacker is based on the player's total thorns value, which can be increased by equipping items with thorns affixes or using skills that boost thorns damage.

Thorns can be a useful stat for tanky builds or for players looking to add some additional damage output to their defensive setup. It can help deter enemies from attacking you directly and provides a way to deal damage even when you are not actively attacking.

Overall, thorns is a strategic attribute that can complement a variety of playstyles in Diablo 4 and is worth considering when planning your character's build.
