Controls how many actors the projectile is allowed to pierce through.
If set to true, the projectile will pierce through breakable objects.
If set to true, the projectile will not pierce objects with healthHaver components (usually referring to enemies).
If set to BEAST_MODE_LEVEL_ONE, then upon impacting a major breakable object that is not a secret wall and does not have 'ImmuneToBeastMode' set to true, 1000 damage will be dealt to the major breakable.
Upon impacting a boss actor, if this variable is set to true 'm_bossImpacts' increments by 1. If the amount of stored boss impacts exceeds the maximum defined in 'MaxBossImpacts', then the projectile loses all ability to pierce or, interestingly, bounce.
Determines the maximum amount of times the projectile is allowed to impact a boss actor if 'UsesMaxBossImpacts' is true.
