Fortitude Runeword

S Tier Armor D Tier Weapon

The Fortitude runeword is created by combining the runes El+Sol+Dol+Lo in 4 socket Weapons or Armor.

Required Runes:
  1. El
  2. Sol
  3. Dol
  4. Lo


The damage bonus when made in Armor is highly sought after for Melee builds and Mercenaries. Don't make Fortitude in a Weapon as it is not worth the Lo rune required.
