Osmium Mail is a campaign-exclusive technology in Age of Mythology that is only available at the Dwarven Forge, which in turn is only featured in The Dwarven Forge, a scenario in Fall of the Trident. Once researched, it decreases the hack vulnerability of infantry, cavalry, and heroes by 20%.

History Edit

"By mining the strongest ore and using special forging techniques that only the Dwarven forge offers, the Dwarves have perfected special armor to protect them during their constant struggle against giants in the Norselands."
