Hair Trigger Buff
This mod simply increases the probability of Hair Trigger being activated to 20% (from 10%). If you have also enabled Advanced Hair Trigger and Superior Hair Trigger, this mod also changes those upgrades to 25% and 30% respectively. Should you want to tweak this, look at the GameCore config file:
Bsc = Basic
Adv = Advanced
Sup = Superior
This mod should apply to campaigns started after the mod was applied, but might not apply if you load into a mission that was started before the mod was applied.
