Relic Nexus Question

[Felis]

I'm just waiting for someone to start the rumor that the drop rate is higher if you go on the job you're collecting for. But only when the moon is full. And you have to face west while killing the final boss of the dungeon. And have to be wearing at least one level 1 piece of gear. Doing all this will increase drop rates by 5%!!! It must be true, cuz I heard a guy, and that guy, you know, totally got the drop when he did this!

There is an easier way.
Do the dungeon as a Ninja and use Mug on the endboss as the last hit.
