  • Trespass only affects the actual bullet damage of a weapon (this value is the "Damage" heading shown on a weapon's stats). Elemental proc damage and DoT will degenerate an enemy's shield before affecting his health. For this reason, it is most effective to use a high-power, non-elemental weapon, such as Whitting's Elephant Gun, for the maximum benefit.
  • Trespass is highly effective against Guardians, due to the fact that it allows Mordecai's bullets to penetrate their powerful shields and directly damage their fragile health.
  • This skill can essentially eradicate the need for Shock weapons/grenades, allowing Mordecai to focus more on his affinity for Corrosion.
  • Although technically not bullets, scattershot projectiles from shotguns and Masher revolvers also gain the benefit of this skill.
  • Since the shield penetration chance becomes guaranteed on level 5 and the damage increase is marginal, skill points can be saved through the use of Peace Keeper class mods.
