C&C ancients, Tactic card text vs Terrain tile rules.

Hi,

I kindly ask if there is a general logic to whether tactic cards always overrule terrain tiles or vice versa?

E.g does the "clash of shields" enable + 2 dice i CC in forest terrain or does the text for the forest tile "maximum 2 dice in CC" overrule?

best regard

the general logic is that the terrain limit applies, but cards add the bonus.

so as an example, a Heavy Infantry attacking a unit in a Forest rolls 2 dice because of the terrain. Using Clash of Shields, it would be 4 dice (2 +2)
