Fortitude is the rune word 'ElSolDolLo' for weapons or body armor in Diablo II: Lord of Destruction.

It can be made both in weapon and armor and in both cases it increases both damage and defense, with even more defense stacked on top of that thanks to the auto-cast Chilling Armor. The damage bonus when made in armor makes it a popular choice for any build centered about physical damage or as a Hireling armor.

Note that +X% Enhanced Damage only works on weapons; on any other item it's converted to Damage +X% instead.
