Question about modding the religious talisman

[Silent Sorrow]

I went into components.txt and changed the entries for the talisman to:

Ability 1 Type:= Combat To Hit Offense Plus
Ability 1 Descr:= Gives a 10% attack bonus in combat (only 1 component per ship effective).
Ability 1 Val 1:= 10

So this means I'm trying to make the talisman give you a 10% bonus to hit.

Now here's my question: Does the Talisman normally override other bonus components such as combat sensors?

Meaning, if a ship has combat sensors III for a 65% to-hit bonus and then has a Talisman (of the 10% kind above) added, would the total to-hit bonus be 85% or does the Talisman override and give 10%.
