Where to get acerus in Pokemon diamond?
Enter this code into your Action Replay (if you dont have one
then i guess your screwed. u can buy one on Amazon.com tho.):
D2000000 00000000 When you activate this code and turn ur game
on, just hold down L and R while you walk into a pokemart, and a
little green dude will give u an Azure flute. go up to spear pillar
and play the azure flute and arceus will apear at trhe top of some
glowy stairs. Arceus is at lvl 80, so be prepared!!! Good
