[kMS] Lol, medals.

Don't even bother with these... They're near impossible.

One requires you to kill 100,000 monsters in 30 days. Oh, and did I forget to mention that the monsters have to be equal to or greater than your level?
Another requires you to have completed 800 QUESTS. Yeah, you know, I only have *BARELY* over 400, so... that should tell you something.
Yet another needs over 1,000 fame.
One more needs an S rank in at least 5 Party Quests. To get an S in most PQs (ACPQ and CPQ excluded) you need to complete it 100 times. The PQ ranking system only came out a few patches ago, so anyone over 70 is pineappleed.

It doesnt sound like it would be worth it to even try to get one of those then...
