"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!"

"Now that he's slagged, he should be easy enough to finish off - switch to another weapon and hit him again"

"Great! The weapons work, and you're ready to take on Handsome Jack. Now, let's talk about your payment"
