Castlevania Lament of Innocence Q&A

How can i go through the statue at the lab? I have already 3 orbs, where can i get those other orbs? Where can i also get the armor?

I cannot double jump and use my whip now because I learned a new technique. Each time I try I come crashing down so I cannot get to higher up balconies anymore, how do I reset this?

how do you beat the mirage skeletons in 1F pagodaof the misty room, to be able to continue on through the locked doors?
