Siege Engineering bonus

[gkmetty]

Hi All,
 
As part of the Siege Engineering trait, Towns and cities attacked (#150 or derivative orders like #160) by a kingdom with Siege Engineering have 10% subtracted from their defense.
 
In the actual battle report this is reflected as fear, Due to the expertise of the Giants siege engineers, the town's defenders were shaken by fear against a possible attack.
 
Does anyone know if this mechanic is part of the maximum fear allowed in battle? Can my group still throw the fear spell for a maximum of 25%?
 
Thanks!

b. Fear is influenced by spells, artifacts, traits, kingdoms, and brigade types. In any battle resolution, the total percent of Fear (reduction in enemy morale) cannot exceed 35 points from all Fear sources for each side. Fear effects to vulnerable brigades are reduces by the percentage of brigades in the group that have immunity via Trait or Ability.

Siege eng. is a trait, so…… part of the max
