Experience modder need help locating a few .scr files

[dovapix]

Hi guy's

 

Just want to make a small mod that change 3 simple things :

 

1-Where is the.scr that deal with skills since i want to make the camouflage skill last 5 min instead instead of 45 sec?

 

2-I also want to change the detection radius of the volatiles so i am not constantly playing the mini game on the mini map.

 

3- I would also like to change virals spawning to a more reasonable level for players who like to have the time to explore locations?

 

I don't want to make the game too easy just less annoying for players who would like to have time to explore without being constantly chase by something.

I have found this in the xml files but i am not sure about certain values specially the one highlight in yellow since i don't understand the 30 value since it doesn't look like second :

 

<skill id="StatusCamouflage" cat="status" tier="11" max_level="1" desc_params="camouflage;M:StatusCamouflage" skill_points="1" skill_points_type="Status">
<level_req type="Status" value="9"/>
<skill_req id="craftingexpertise"/>
<effect id="CamouflageEnabled" change="1"/>
</skill>

<skill id="StatusCamouflage2" cat="status" tier="21" max_level="1" desc_params="camouflage_attack;P;M:StatusCamouflage2" skill_points="1" skill_points_type="Status">
<level_req type="Status" value="12"/>
<skill_req id="StatusCamouflage"/>
<effect id="CamouflageDuration" change="30"/>
<effect id="CamouflageLooseOnGiveDamage" change="x-1"/>
</skill>
