GetAdditionalHitModifiers
Tracking Issue: #1271
This feature adds a method that can be used by subclasses to apply
additional hit modifiers without having to override and copy paste
the entire GetHitChance() function.
Override this method in subclasses to apply additional hit modifiers.
Using the existing AddModifier() function is recommended, for example:
AddModifier(10, "localized reason", m_ShotBreakdown, eHit_Success, bDebugLog);
