Troop Upgrades and Bonuses... do they stack

[svensven]

EX: If a +50% against Melee Units has a +20% City Attack upgrade, and it attacks a city which is defended by a melee unit, does it get both bonuses?

Yes.

They also keep the upgrade after you upgrade it to another troop type.

 

[Pragmatic]

But how do they stack? Do they stack arithmetically (i.e., do +50% and +20% give you +70%)? Or do they stack geometrically (i.e., do +50% and +20% give you 150%x120% = 180% = +80%)?

 

[Brota]

They stack on the base strength modifier I believe.

The game adds the percentages together then multiplies the strength by the percent, I believe.

For example, an Axeman with Combat 2 would be strength 8.5 vs a melee unit.
