reducing attrition during sieges

[godfather_77]

Is there a technology that I can research to reduce the amount of attrition when trying to starve out a an enemy during a siege? Any suggestions welcome! I am playing Rome and using Radius’ total war mod

The barbarian factions have a lot of those in the siege part of their military research chain. The other factions should have some too.

Should be in your siege tree. Different for almost every faction, so I can't give you the exact tech, since I don't know your exact faction.

It's in the siege technology tree. I think it's the last one but it reduces attrition by almost 60% to the point that when it occurs you barely notice it.
