Stamp of the Betrayer

[camelotcrusade]

This magical item has a short description, saying only "+20% damage of the soldiers." Sounds good to me, so I bought one. It didn't change the damage numbers on my display screen, though, so I reloaded it (cost me 21k).

The info text makes it sound like "soldiers" should take 20% more damage. That could be it, but my next question is what qualifies as a soldier? Any old troop?

Wondering if anybody has used this item and/or can confirm what it does...

PS. Here is some code where I found it, but I don't know all the places to look.
