Claptrap Skill Tree 1.png

Boomtrap is Claptrap's first skill tree. This skill tree focuses on explosive damage through guns and skills, with some bonuses to guns in general. His other skill trees are I Love You Guys! and Fragmented Fragtrap.


Tier 1
  • Drop the Hammer - Reloading your weapon increases your fire rate and reload speed by +5% each but makes your accuracy worse by -2% per rank, for a few seconds.
  • Killbot - Killing an enemy heals you for up to 7% of your max health but drains 2% of your max shields per rank. The lower your health, the more healing you receive.
Tier 2
  • Coincidental Combustion - Whenever you shoot an enemy with a non-Explosive weapon, you have a 7% chance per rank to deal bonus Explosive damage. The bonus damage is based on the weapon's damage.
  • Repulsive - When struck by a melee attack, you emit a powerful Blastwave that pushes enemies away and deals Explosive damage; the Blastwave's radius increases with rank. Has a 5 second cooldown.
Tier 3
  • Second Wind (by Tediore) - When you enter Fight For Your Life, you throw a digistructed copy of yourself that explodes like a grenade, and constantly emit Explosive novas.
Tier 4
  • Load 'n' Splode - Whenever you reload your gun, you gain +4% increased Explosive damage per rank for a few seconds. Stacks up to 5 times.
  • I Am Rubber, You Are Glue - Kill Skill. When you kill an enemy, bullets have a 25% chance to reflect off you and towards enemies for a short time. Unlocks the ACTION PACKAGE Torgue Fiesta.
  • Start With a Bang - Firing a fully loaded gun after reloading causes an Explosive Nova centered on you with damage based on your rank, but drains 1% of your current health per rank.
Tier 5
  • Hyperion Punch - Melee Override. Dealing Explosive damage adds a stack of Hyperion Punch. Once you have 5 stacks, press [melee] to throw a punch that deals bonus Incendiary Damage and consumes all stacks. Bonus damage increases with rank.
  • One Last Thing - The last shot in the magazine of any weapon deals +80% damage per rank. Weapons with a magazine size smaller than 8 receive a reduced bonus.
Tier 6
  • Livin' Near the Edge - Increases fire rate and reload speed by up to +100% each. The lower your health and shields, the greater the bonus. Unlocks the ACTION PACKAGE Pirate Ship Mode.
