This runeword can be made only on Ladder but it is obtainable on Non-Ladder via trade because all Ladder characters convert to NLD after reset. There are no Ladder-only runewords in D2R, you can make everything on NLD.

Fortitude grants 20% chance to cast level 15 Chilling Armor when struck (Sorc buff usable by any class). It lasts for 4 minutes, gives 115% bonus defense and launches Ice Bolts towards ranged attackers for 28-38 damage. It will have 100% uptime vs monsters.

You can learn more about game mechanics behind those abilities in our game guide.

Archon Plate (AP) vs Sacred Armor (SA):
Eth AP requires only 93 Strength and has the highest defense from all light armors (they don't slow movement speed).
Eth SA is medium armor and has the highest defense overall but also the highest Strength required (only high level merc can reach 222 Str with items). It will also make him walk/run 5% slower but it is not important for merc, especially if you move around with Teleport.
