How can I get through the 3rd room of the sceptre of hamara?

In the 3rd room you have to search for an obelisk. When you turn it, a gate opens, which gives you access to a room full of lava. Search for the room. When you're there, a voice will whisper something like "let thy heart guide thee". You have to just jump in the lava, if you do that in the middle, the ground will appear under you (remember to save your game in case it doesn't work, 'cause you have to fall in the middle or the ground won't appear). You can walk on to the other side like this, there you'll have to defeat an enemy (some kind of skull) to get to the scepter.

In 3rd room I turn obelisk but gates don't open try it many times:((((what to do?

There are two obelisks that you must turn.

1-you must turn an oblesik
2-another hate will open inside it another oblesik
3-oblesiks are like switches
4-when you activate both switches(obleskis) a gate will be opened to boss
5-Al last a room full of lava will be in front of you
6-save game(in cause it doesnt work)
7-you will find some words(belive in your heart)something like that
8-pass and a road will come as if you r jumping on something(you must walk in mid)(you will lose a little hp)

The last guest is correct but remeber, the obelisk are nit very far from the gate that they lift up so don't go to far from the gate. U dnt need to go way back through the maze. Try not to get confused and you dnt have to back track to hard to find the obs.
