It's da truth, bro.

For an explanation of what's going on, this is the second fight against Doopliss while having Double Pain and Return Postage (from doing a PreHooktail Pit of 100 Trials run) equipped, as well as having a bunch of Spite Pouches.

Conveniently, Spite Pouches stack with Return Postage. This lets me do a lot of damage by not attacking... at all... :3
