  • Due to its tremendous damage, this weapon can easily kill even Heavy Zombies and Venom Guards.
  • The special shot can do a headshot but only with its initial impact.
  • Like Hunter X-12 it's unwise to have this weapon out during Zombie Modes....unless you're charging the weapon, do this because if people see you having the weapon out they're going to assume that you have it ready to fire the pillar, this results on very few confrontations in small groups which makes it harder to get kills and harder to defend against.
  • Having a weapon with a high stun and affecting a large surface Gunslinger, Dread Nova, Phantom or Thunder-Ghost allows you to stun a zombie within your pillar, so they won't be able to escape.
  • Always aim for the floor with this weapon, the pillar itself is most likely going to kill the zombie aiming for the zombie has an extreme chance of missing and it's honestly not worth the additional 5-10k damage output, the only exception is if the zombie is stunned...then try to body or even headshot it.
    • After the dragons are summoned, it can kill literally anything within the radius. (even on the slight chance it doesn't a single extra shot should do the job
    • The dragon wave lasts 4 seconds.
