Start With a Bang is a tier 4 skill in Claptrap's Boomtrap skill tree.

When firing the first bullet of a gun's magazine, Claptrap emits an Explosive Nova at the cost of 1% of current health.

  • This skill works well with a melee focused Claptrap since the radius of the nova is rather small.
  • It is not advisable to attempt to use this skill with a Tediore build due to the chance of Claptrap destroying himself along with his targets.
  • Start With a Bang's damage is increased by Load 'n' Splode skill, but is not affected by grenade damage bonuses.
  • If Claptrap's shield is not depleted the self damage hits it instead of his health.
