  • The user can inflict self-damage within the harpoon's explosion radius.
  • The harpoon can be set to explode manually by clicking alternate fire button (Default: Right Click Mouse Button) after the harpoon is launched. The damage dealt is also significantly higher.
  • You can avoid receiving fatal damage from falling off using the harpoon's explosion knockback; just before making contact with the ground, detonate the harpoon pre-maturely. The user would negate the fall damage, only losing a bit of health from the harpoon's explosion.
  • There's a trick whereby a player can perform a headshot no matter where the harpoon hits. To achieve it, the player must have previously shot the enemy with a secondary weapon in the head and then proceed to use the Gae Bolg.
  • You can access unreachable spots by taking advantage of its explosion knockback.
  • Before exploding, harpoons are able to drag anything that are caught by them.
  • Harpoon's explosion deals only 10 damage to nearby enemies. However, it can do instant kill in direct hit.
Zombie Scenario
  • Harpoons explodes upon hitting bosses and mini-bosses.
  • Gáe Bolg's harpoon deals around 14000 ~ 21,000 damage to bosses on mostly any part of the body, as long as you have the firepower maxed out.
  • 30 rounds of the Gáe Bolg's harpoon deals 420,000 ~ 630,000 damage to bosses, provided that the firepower has been maxed.
  • Since it has a long reload time, try to avoid incoming zombies.
Zombie Infection
  • A harpoon of Gáe Bolg can deal around 1700 ~ 13000 damage towards a zombie while the explosion inflicts around  200 ~ 400 damage against a group of them. 
  • The harpoons possess quite powerful push power that it can take out up to two zombies away with ease.
  • If friendly fire is allowed, you can use it to push your teammates away too. If there's no friendly fire allowed, harpoons simply passed through their bodies until it explodes or make contact with a surface.
  • Do not spam shot due to its low magazine capacity.
