Claptrap the Fragtrap

Balanced • Subroutine

PLAYSTYLE

Claptrap can be one of the more intimidating choices in Borderlands The Pre-Sequel because of the randomness associated with not just his action skill, which can be assigned a random action package, but also his subroutines that randomly swap out for different effects. This sounds complicated on paper, but it’s a lot of fun in practice, and this build focuses on all his trees to ensure that he gets a lot of damage despite the randomness factor along with health.

The game plan is pretty simple, you want to go in, start doing damage, and if you aren’t happy with a subroutine, you can switch it out outside of combat encounters by slamming to the ground, and changing and deducting your frag stacks which will then target a different weapon type.

SOLO

This is a great build for solo play because it turns Claptrap into a killing machine that does a ridiculous amount of explosive damage, and since we have a variety of weapons in our gear, we can switch to a different weapon type based on the current subroutine in place. This build also provides room for flexibility, so you’re never stuck with one strategy that’s forced down on you due to the randomness factor. Claptrap also gets tons of healing thanks to our investment in the I Love You Guys! tree.

COOP

Similarly, this Claptrap build introduces a decent amount of randomness that can contribute to a very fun playthrough, especially if someone is willing to experiment and adapt to the randomness thrown at Claptrap during combat encounters. He will need some healing from time to time, but inversely, Claptrap will provide bonuses to the entire team as well thanks to his Action Skill.

SKILLS

Second Wind (by Tediore) throws out a digistructed Claptrap that explodes near an enemy when you enter Fight for Your Life. Tripleclocked multiplies your active Subroutine bonuses and Penalties by up to 3 while Fuzzy Logic increases your critical damage by 30% for 5 seconds and resets every time you get hit.

Drop the Hammer increases Claptrap’s fire rate and reload speed by 25% while reducing accuracy by 10% whenever you reload, and All The Things are Awesome also increases his fire rate by 15%.
