Marcus: Now, let's try out these new slag weapons! Slag is a bit more complex. If you slag your enemy, all non-slag damage will hurt even more! Here -- slag this chump.
Shoplifter: This planet belongs to HYPERION, you savages!
(If any other than slag weapon is used ...)
Marcus: No, no, no -- slag him first!
(Vault Hunter fires at the target with a slag weapon.)
Marcus: Now that he's slagged, he should be easy enough to finish off. Switch to another weapon and hit him again.
(If slag weapon is used again ...)
Marcus: To do full damage, you'll want to switch to another weapon once your enemy has been slagged.
(Vault Hunter switches to another weapon and fires at the target.)
Marcus: Great! The weapons work, an you're ready to take on Handsome Jack. Now, let's talk about your payment.
(Vault Hunter turns in the mission to Marcus.)
Marcus: If you want to purchase any elemental weapons like these, you could always buy some from your friendly neighborhood arms dealer.
