How do you get Arceus on Pokemon sky?

hi, in Pokemon Mystery Dungeon explorers of sky you cannot get arceus thru regular gameplay. However, make as many drinks at spinda cafe as you can becauseyou could unlock destiny tower. Destiny tower has 99 floors and only they leader can go in and i think you will be temporarily level one when you enter but i am not sure. at the top there is an arceus statue, next to it is a space globe wich raises attack power by150%! Wow! it is very useful even though i hacked mine.
