Purple item in first boss fight arena ?

[astranabeat]

How to get to it ? too high to jump and I can't a find a way to get around to it.

Climb the tree, there's another spot to drop down to get it.

Yes, you've to climb the tree, then go left or so pick up an item, and a little more closer to the ground there's another 'rope'
