What does luck do exactly?

[Moonwraith]

Hey Sariana, welcome to the forums! As a semi-newbie here myself, I'll let other people tell you what thou shallst not do

Anyways, yeah, Luck affects crits and nothing else. Not rares, not megid, not anything. Just crits.

Second of all, I dunno...I have a pretty high luck rating with my RAmar, and on his game alone I've gotten a total 15 Photon Drops, not to mention several rares. Of course, it might have something to do with his Section ID; I've heard that Purplenums get a lot of rares.

Section ID generally has nothing to do with how many rares you get - just what rares you get. Purplenum is good for mechs, for example. You'll get Photon Drops irrespective of ID though, with the same drop rates for all IDs.

The Megid thing...again, I'm not sure. I've had some instances where Ob Lillies can Megid at me till they're blue in the face, and it doesn't affect me. Other times I get hit once, and I'm dead.

Luck doesn't affect Megid at all - the only things that do are EDK, and Megid level.
