Você precisa vir por cima, escorregar na cachoeira até chegar nesta pedra, fica bem no meio da cachoeira (não sei se dá para vir aqui pelos lados)

Two options to get to this knowledge point - you can either try and do a gap closer on a ledge above the Haeam tomb and hopefully not overshoot it, or go from above going past the little Musa home.

I was a lot more successful with the top-down approach. But a short-gap class might be able to close it without issue.

Id suggest from the Kebbichest, zoomed into your mini map, right click and mark the super tiny ledge on the mini map. It is a very very specific ledge to jump on. After you mark it, you'd not have a problem aiming for it when you jump from the Kebbichest at the top
