just for the record, there are no staged pets, only staged skills... tho staged angel skins are prolly available if you utilize the skin from ToA/ToE dont (remember which) dungeon that has the "staged angels"
It's TOE that has the staged angel, I believe it's only the evo 2 skin but should be possible to use it's model for evo 2 angel in place of the original ^^ as far as server's I'd say go to Redemption or wait for Montes.
